Your heart gets a lot of attention from poets, songwriters, and storytellers, but today Hank's gonna tell you how it really works. The heart’s ventricles, atria, and valves create a pump that maintains both high and low pressure to circulate blood from the heart to the body through your arteries, and bring it back to the heart through your veins. You'll also learn what your blood pressure measurements mean when we talk about systolic and diastolic blood pressure.

It is the product of STROKE VOLUME – the amount of blood pumped in one heartbeat, and HEART RATE – the number of beats in one minute. An INcrease in either stroke volume or heart rate results in INcreased cardiac output, and vice versa. For example, during physical exercises, the heart beats faster to put out more blood in response to higher demand of the body. It is noteworthy that the ventricles do NOT eject ALL the blood they contain in one beat. In a typical example, a ventricle is filled with about 100ml of blood at the end of its load, but only 60ml is ejected during contraction. This corresponds to an EJECTION fraction of 60%. The 100ml is the end-DIASTOLIC volume, or EDV. The 40ml that remains in the ventricle after contraction is the end-SYSTOLIC volume, or ESV. The stroke volume equals EDV minus ESV, and is dependent on 3 factors: contractility, preload, and afterload. Contractility refers to the force of the contraction of the heart muscle. The more forceful the contraction, the more blood it ejects. PRELOAD is RELATED to the end-diastolic volume. Preload, by definition, is the degree of STRETCH of cardiac myocytes at the end of ventricular filling, but since this parameter is not readily measurable in patients, EDV is used instead. This is because the stretch level of the wall of a ventricle INcreases as it’s filled with more and more blood; just like a balloon - the more air it contains, the more stretched it is. According to the Frank-Starling mechanism, the greater the stretch, the greater the force of contraction. In the balloon analogy, the more inflated the balloon, the more forceful it releases air when deflated. AFTERLOAD, on the other hand, is the RESISTANCE that the ventricle must overcome to eject blood. Afterload includes 2 major components: - Vascular pressure: The pressure in the left ventricle must be GREATER than the systemic pressure for the aortic valve to open. Similarly, the pressure in the right ventricle must exceed pulmonary pressure to open the pulmonary valve. In hypertension for example, higher vascular pressures make it more difficult for the valves to open, resulting in a REDUCED amount of ejected blood. - Damage to the valves, such as stenosis, also presents higher resistance and leads to lower blood output.

Cure High Blood Pressure Stop Heart Attacks Natural : No Medication is a video put together to inform those that are looking for a natural non chemical no medication way to not only lower blood pressure in minutes,but if used continuously along with regular exercise,and healthy diet eliminate it altogether. Read on to learn other facts not put in the video. What is in the video is all about lowering blood pressure quickly. Please share this video with your friends and loved ones. 1) Raw almonds. Eating just a handful of truly raw almonds every day can make a significant difference in keeping your blood pressure levels in check. A key component of the Dietary Approaches to Stop Hypertension Diet, also known as DASH, raw almonds are rich in monounsaturated fats, which have been scientifically proven to help lower blood cholesterol levels, reduce arterial inflammation, and ultimately lower blood pressure levels. Even though they are high in fat and calories, almonds also help promote weight loss and the building of lean muscle mass, which means they naturally promote healthy circulation. When eaten in conjunction with other blood pressure-lowering nuts like walnuts, almonds are one of the most powerful cardiovascular "superfoods" available. 2) Cayenne pepper. Arguably one of the fastest foods to lower blood pressure, cayenne pepper is a powerful vasodilator, which means it helps expand blood vessels and improve blood flow. This effect naturally lowers blood pressure levels by increasing the rate at which blood flows throughout the circulatory system, which in turn takes some of the pressure off arterial walls. Mixing one or two teaspoons of cayenne pepper in either warm water or tea with both honey and aloe vera is a powerful homemade remedy for alleviating hypertension. If this beverage is too spicy for your tastes, taking cayenne pepper capsule supplements is another great option for lowering blood pressure naturally. 3) Coconut water. Rich in potassium, electrolytes, and other important nutrients, coconut water has been shown to help significantly lower blood pressure levels in most of the people that drink it. A recent study published in the West Indian Medical Journal found that drinking coconut water helped 71 percent of participants achieve a significant reduction in systolic pressure, and 29 percent of participants achieve a significant reduction in diastolic pressure. The results were even more amplified when participants drank both coconut water and mauby, a tropical drink made from buckthorn tree bark. 4) Raw cacao. Rich in flavonoids and other anti-inflammatory nutrients, raw cacao is another food-based weapon against hypertension that you will want to keep readily stocked in your health arsenal. Not only do the flavonoids in cacao function as adaptogens to help the body better deal with stress, which is a common cause of hypertension, but they also help regulate stress hormone levels throughout the body, which play a critical role in blood pressure regulation. Numerous studies have also found that cacao flavonoids demonstrably reduce blood pressure levels upon consumption, resulting in an average blood pressure reduction of 4.7/2.8 millimeters of mercury (mmHg). Cacao flavonoids also help protect the body against stroke and heart disease, which are commonly linked to high blood pressure. 5) Turmeric. Modern science is just barely hitting the tip of the iceberg concerning the superfood capacity of turmeric, also commonly known as curcumin. But one of the herb's already known benefits concerns its abilities to significantly decrease inflammation throughout the body, which is a primary cause of high cholesterol and even high blood pressure. By actively reducing inflammation, turmeric helps improve cardiovascular function and maintain healthy blood flow. When taken alongside non-irradiated black pepper, the primary active ingredient of which is piperine, turmeric is a powerhouse at loosening up blood vessels and clearing the buildup that often leads to high blood pressure. Turmeric is also a natural blood thinner, which is another way this powerful herb aids in the fight against hypertension. 6) Garlic. A 2010 study out of Australia found that garlic is another powerful food-based medicine that naturally lowers cholesterol levels and reduces blood pressure. Taking garlic tablets or capsule supplements is a great way to regularly consume the herb in high enough amounts to derive significant benefits.

All rights reserved. Voice by: Sue Stern. Support us on Patreon and get FREE downloads and other great rewards: patreon.com/AlilaMedicalMedia The cycle is initiated with the firing of the SA node that stimulates the atria to depolarize. This is represented by the P-wave on the ECG. Atrial contraction starts shortly after the P-wave begins, and causes the pressure within the atria to increase, FORCING blood into the ventricles. Atrial contraction, however, only accounts for a FRACTION of ventricular filling, because at this point, the ventricles are ALREADY almost full due to PASSIVE blood flow DOWN the ventricles through the OPEN AV valves. As atrial contraction completes, atrial pressure begins to FALL, REVERSING the pressure gradient across the AV valves, causing them to CLOSE. The closing of the AV valves produces the first heart sound, S1, and marks the beginning of SYSTOLE. At this point, ventricular depolarization, represented by the QRS complex, is half way through, and the ventricles start to contract, RAPIDLY building UP pressures inside the ventricles. For a moment, however, the semilunar valves remain closed, and the ventricles contract within a CLOSED space. This phase is referred to as isovolumetric contraction, because NO blood is ejected and ventricular volume is UN-changed. Ventricular ejection starts when ventricular pressures EXCEED the pressures within the aorta and pulmonary artery; the aortic and pulmonic valves OPEN and blood is EJECTED out of the ventricles. This is the RAPID ejection phase. As ventricular repolarization, reflected by the T-wave, begins, ventricular pressure starts to FALL and the force of ejection is REDUCED. When ventricular pressures drop BELOW aortic and pulmonary pressures, the semilunar valves CLOSE, marking the end of systole and beginning of diastole. Closure of semilunar valves produces the second heart sound, S2. The first part of diastole is, again, isovolumetric, as the ventricles relax with ALL valves CLOSED. Ventricular pressure drops RAPIDLY but their volumes remain UNchanged. Meanwhile, the atria are being filled with blood and atrial pressures RISE slowly. Ventricular FILLING starts when ventricular pressures drop BELOW atrial pressures, causing the AV valve to open, allowing blood to flow DOWN the ventricles PASSIVELY.

Many people suffer from heart attacks and high blood pressure. What causes these problems to occur? The first symptom of a heart attack in most cases is death. High blood pressure is considered the "silent killer" because you don't realize you have a problem until the damage has been done. Subluxation's present with no symptoms but do interfere with how the nervous system communicates to the other body systems and affects how they function.

Support us on Patreon and get FREE downloads and other great rewards: patreon.com/AlilaMedicalMedia Venous return is the flow of blood from the periphery back to the heart’s right atrium. Blood from the upper body returns via the superior vena cava, blood from the lower body returns via the inferior vena cava. The rate of venous return is determined by two factors: the pressure gradient between venous pressure and right atrial pressure; and venous resistance. A decrease in right atrial pressure leads to an increase in venous return, and vice versa. Breathing is one of the mechanisms that facilitate venous return. This is known as thoracic pump, or respiratory pump. During inspiration, the diaphragm moves down, expanding the thoracic cavity, resulting in a decreased intra-thoracic pressure and a subsequent expansion of the lungs. Part of this change in pressure is transmitted across the walls of the heart, lowering right atrial pressure and thus facilitating venous return. Another aspect of the diaphragmatic descent is the concomitant increase in abdominal pressure. As the inferior vena cava passes through both abdominal and thoracic cavities, an increase in abdominal pressure together with a decrease in thoracic pressure squeeze the blood upward - toward the heart. On the other hand, left ventricular stroke volume is decreased during inspiration. This is because the expansion of the lungs causes pulmonary blood volume to increase and the blood flow from the lungs to the left atrium to decrease. During expiration, the diaphragm moves up, the pressure in the thoracic cavity reverses. Venous return decreases. Pulmonary blood vessels shrink pumping more blood through the pulmonary veins into the left atrium. Stroke volume increases as a result.

As part of a blood pressure therapy program, regular use of an infrared sauna is good for your heart. In the U.S. alone, one in three adults suffers from heart disease, stroke or some other form of cardiovascular disease in their lifetime. High blood pressure increases your risk of getting heart disease, kidney disease or serious stroke. Only Sunlighten saunas have been clinically determined to provide one of the best, natural ways to lower blood pressure. In a 2005 clinical study by the University of Missouri Kansas City, our sauna was shown to lower blood pressure through a program of 30 minute infrared sauna session 3 times per week. The study concluded that infrared sauna therapy dilated blood vessels and reduced the volume of their inner lining, thus increasing circulation to promote healthy blood pressure. Additionally, a Japanese study published in the October 2008 issue of The Journal of Cardiology examined the clinical effectiveness and safety of infrared blood pressure therapy, as compared to standard therapies for patients with chronic heart failure. The report concluded that far-infrared sauna therapy is both safe and effective at improving clinical symptoms and cardiac function as well as decreasing cardiac size in chronic heart failure patients. Repeated infrared sauna treatments improved impaired blood vessel functions in patients with high blood pressure, diabetes and high cholesterol. This suggests a preventive role for infrared sauna use for arteriosclerosis. All of these benefits can keep you in a healthy, active lifestyle. As with all of our therapies here, that is our goal.

Do you want to clean your blood vessels? How to decrease the risk of heart attacks in the future? Are you ready to improve your overall well-being? Here are 15 food products that can take care of your heart and prevent heart diseases. Our heart is one of the most important organs, but, surprisingly, we take care of it the least, loading it every day with stress and unhealthy diets. And that's too bad because fatty food increases cholesterol levels, which leads to vascular plaques that prevent the heart from working correctly. In this video, you will get familiar with 15 products that perform all these activities! Some of them might surprise you with their health benefits! Watch till the end - as a bonus, you will find a recipe for a special drink for healthy blood vessels. And remember to press the like button in appreciation of our work! TIMESTAMPS Fatty fish 1:05 Oatmeal 1:51 Berries 2:30 Dark chocolate 3:19 Nuts 4:00 Extra virgin olive oil 4:45 Red wine 5:23 Green tea 5:53 Broccoli and spinach 6:35 Avocado 7:39 Pomegranate 8:13 Cinnamon 8:43 Watermelon 9:14 Garlic 9:43 Apples and pears 10:28 SUMMARY - Salmon, mackerel, herring, haddock, and other fatty fish decrease the risk of arrhythmia and atherosclerosis. They also contain lots of vitamins as well as minerals. - Rich in fiber, porridge decreases the levels of "bad" cholesterol and improves digestion. Coarse oatmeal is the healthiest. - Blueberries and strawberries are very good at lowering blood pressure and dilating blood vessels. Strawberry-lovers also get fiber, folate, antioxidants, and potassium from their favorite berries. - Dark chocolate provides the anti-stress effect as it increases the production of serotonin which is known for its calming effect. Cocoa, the main component of dark chocolate, also helps to prevent memory decline. - Nuts contain protein fibers that are useful for the heart. They also have vitamin E as their ingredient which helps to decrease the levels of "bad" cholesterol. - Olive oil is very high in oleic acid which reduces blood pressure. It is interesting that when the olives are crashed, oil leaves them naturally; therefore, beneficial ingredients and vitamins are not harmed by chemicals or preservatives. - French scientists have also found out that red wine contains some elements which can prolong a human lifespan for about 60 percent! Saying this, it still should be consumed in moderation. - Green tea makes the brain function better. This drink may decrease the risk of different types of cancer (such as prostate and breast cancer). - Broccoli, in particular, has a lot of medicinal benefits, such as prevention of some kinds of cancer, digestive system improvement, detoxification of the body. It also resembles a vitamin injection, filling you with numerous vitamins and minerals. - Avocados are packed with fiber, which can be useful for weight loss, blood sugar reduction, and other health-benefitting processes. - Pomegranates contain antioxidants, lower blood pressure, normalize blood circulation and increase hemoglobin levels. - Cinnamon can protect you from heart diseases and atherosclerosis. It also boosts metabolism and helps you to lose weight. - Watermelon plays an important role in vascular health. It stabilizes the cholesterol levels and contains antioxidants. It provides hydration, which is a great thing for your body. - Garlic dilates the vessels, lowers blood pressure, alleviates vasoconstriction, and prevents atherosclerotic plaques from appearing. It improves digestion as well, assisting in the functioning of the intestines. - Apples and pears are rich in fiber that helps your heart. They normalize blood circulation and are cheaper and more readily available alternatives to pomegranates. Besides, apples will help to maintain white and healthy teeth.

www.DanHammerHealth.com This is a recording of a live webinar entitled "How to Take the High Out of High Blood Pressure!" It contains valuable information that can help you find a natural solution to your high blood pressure concerns. In this video we provide you with information about the endothelium and nitric oxide. Your endothelium lines all of your cardiovascular system and controls your blood pressure through various biochemicals that it releases into the bloodstream. One of which is nitric oxide -- the master signaling molecule of your entire cardiovascular system. Nitric oxide performs 3 specific functions one of which is to relax the smooth muscle of the vascular wall to help keep your blood pressure in a normal range. In this video we talk about what damages the endothelium and how to nourish and repair the endothelium. This organ and its ability to properly produce nitric oxide is critical in helping you maintain a normal blood pressure. If you have any questions or concerns, then please contact me at 1-800-966-3012 or email me at firstname.lastname@example.org Dan Hammer www.DanHammerHealth.com

Ingredients mentioned in this video with their descriptions: Taurine 500mgs - Taurine may facilitate the transport of Potassium into and out of the body's Cells and may help to prevent and treat Cardiomyopathy. Taurine concentrates in the Heart references and (5000-6000 mg per day of supplemental Taurine) may alleviate Ischemic Heart Disease. By normalizing Potassium flow into and out of Cardiac Muscle cells, Taurine normalizes the electrical excitability of the Cell Membranes of Cardiac Muscle and enhances the contractile strength of the Cardiac Muscle. Taurine modulates the activity of cyclic AMP within Cardiac Muscle. Persons who have experienced a Heart Attack often exhibit very low Taurine levels subsequent to their Heart Attack (indicating that supplemental Taurine may be highly advisable for persons who have experienced a Heart Attack). Taurine may also help to prevent a Heart Attack as it may help prevent potentially lethal Arrhythmias after Heart Attacks. Taurine is the most abundant and most important Amino Acid in the Heart (it is present in the Heart in greater quatities than all other Amino Acids combined). Taurine (6000 mg per day) may lower Blood Pressure in Hypertension patients (by suppressing Renin-Angiotensin). It usually requires four weeks of daily supplementation with Taurine before its Blood Pressure lowering effects occur. Magnesium Citrate or Malate - Magnesium may exert antispasmodic effects on Blood Vessels. Magnesium supplementation may improve Heart function in Cardiomyopathy patients. It may also be beneficial for the treatment of Dilated Cardiomyopathy. Magnesium may prevent and treat most types of Cardiovascular Diseases. Approximately 85% of Mitral Valve Prolapse patients exhibit Magnesium deficiency and oral Magnesium supplementation (600-1800 mg per day) may alleviate many cases of Mitral Valve Prolapse. Magnesium supplementation may provide significant protection against Strokes (the Blood Vessels that supply the Brain are prone to vascular spasm during Magnesium deficiency and these vascular spasms that occur during Magnesium deficiency may result in a Stroke. With Magnesium supplementation, the Cerebral Arteries may relax and Blood Circulation to the Brain may improve). Magnesium (administered within six hours after the occurrence of a Stroke) may reduce the after-effects of Strokes. 100mgs and Potassium citrate 99mgs--this will regulate the heart and initially use each dose of each 3 times per day. Potassium is a very important mineral for the proper function of all cells, tissues, and organs in the human body. It is also an electrolyte (a substance that conducts electricity in the body) along with sodium, chloride, calcium and magnesium. Potassium is crucial to heart function and plays a key role in skeletal and smooth muscle contractions making it important for normal digestive and muscular function. Other studies show that increasing potassium intake reduces the risk of dying from cardiovascular disease. Researchers suspect that this is largely due to potassium's blood pressure lowering effects. Hawthorn Leaf - may improve the utilization of Oxygen by the Cardiac Muscle and improves Blood Circulation to the Cardiac Muscle. Hawthorn may prevent and treat many Cardiovascular Diseases. Hawthorn (pretreatment) may minimize the Brain damage that occurs after the occurrence of an ischemic Stroke. It may also protect the Heart against Hypoxia. Hawthorn may alleviate Congestive Heart Failure (CHF) by increasing the strength of Cardiac Muscle contractions and increasing blood circulation to the heart and by reducing the resistance of blood circulation in peripheral tissue. Hawthorn may also improve the production of energy within the heart and may improve the contrations of the heart muscle wall (the Myocardium) allowing it to more efficiently pump blood through the body and also protects the heart against Hypoxia. Hawthorn and Ginger Root may increase the contraction strength of the heart and may improve Energy production in the heart (due to its ability to increase the production of Adenosine Triphosphate (ATP) by the heart. Recipe: to make a tea, take about a 3 inch slice of ginger--peel and chop--and add equal amounts of either Hawthorn Berry or Leaf and bring to a boil. Or, you can percolate this or take the same portions and and extract them in alcohol. Olive Oil - Visioli and Galli reported that Oleuropein shows anti-athergenic activity. In 2003, Carluccio MA et al. reported that oleuropein reduces monocytoid cell adhesion to stimulated endothelium as well as vascular cell adhesion molecule-1. Reflow in ischemic hearts was accompanied by a prompt release of oxidized glutathione in ischemic hearts pretreated with oleuropein. This release was significantly reduced and was accompanied by prevention of membrane lipid peroxidation, which is considered a key factor in the pathogenesis of atherosclerosis.

The cardiovascular system is subject to precise reflex regulation so that an appropriate supply of oxygenated blood can be reliably provided to different body tissues under a wide range of circumstances. The sensory monitoring for this critical homeostatic process entails primarily mechanical (barosensory) information about pressure in the arterial system and, secondarily, chemical (chemosensory) information about the level of oxygen and carbon dioxide in the blood. The parasympathetic and sympathetic activity relevant to cardiovascular control is determined by the information supplied by these sensors. The mechanoreceptors (called baroreceptors) are located in the heart and major blood vessels; the chemoreceptors are located primarily in the carotid bodies, which are small, highly specialized organs located at the bifurcation of the common carotid arteries (some chemosensory tissue is also found in the aorta). The nerve endings in baroreceptors are activated by deformation as the elastic elements of the vessel walls expand and contract. The chemoreceptors in the carotid bodies and aorta respond directly to the partial pressure of oxygen and carbon dioxide in the blood. Both afferent systems convey their status via the vagus nerve to the nucleus of the solitary tract, which relays this information to the hypothalamus and the relevant brainstem tegmental nuclei (located in brain stem). The afferent information from changes in arterial pressure and blood gas levels reflexively modulates the activity of the relevant visceral motor pathways and, ultimately, of target smooth and cardiac muscles and other more specialized structures. For example, a rise in blood pressure activates baroreceptors that, inhibit the tonic activity of sympathetic preganglionic neurons in the spinal cord. In parallel, the pressure increase stimulates the activity of the parasympathetic preganglionic neurons in the dorsal motor nucleus of the vagus and the nucleus ambiguus that influence heart rate. The carotid chemoreceptors also have some influence, but this is a less important drive than that stemming from the baroreceptors. As a result of this shift in the balance of sympathetic and parasympathetic activity, the stimulatory noradrenergic effects of postganglionic sympathetic innervation on the cardiac pacemaker and cardiac musculature is reduced (an effect abetted by the decreased output of catecholamines from the adrenal medulla and the decreased vasoconstrictive effects of sympathetic innervation on the peripheral blood vessels). At the same time, activation of the cholinergic parasympathetic innervation of the heart decreases the discharge rate of the cardiac pacemaker in the sinoatrial node and slows the ventricular conduction system. These parasympathetic influences are mediated by an extensive series of parasympathetic ganglia in and near the heart, which release acetylcholine onto cardiac pacemaker cells and cardiac muscle fibers. As a result of this combination of sympathetic and parasympathetic effects, heart rate and the effectiveness of the atrial and ventricular mycoardial contraction are reduced and the peripheral arterioles dilate, thus lowering the blood pressure. In contrast to this sequence of events, a drop in blood pressure, as might occur from blood loss, has the opposite effect, inhibiting parasympathetic activity while increasing sympathetic activity. As a result, norepinephrine is released from sympathetic postganglionic terminals, increasing the rate of cardiac pacemaker activity and enhancing cardiac contractility, at the same time increasing release of catecholamines from the adrenal medulla (which further augments these and many other sympathetic effects that enhance the response to this threatening situation). Norepinephrine released from the terminals of sympathetic ganglion cells also acts on the smooth muscles of the arterioles to increase the tone of the peripheral vessels, particularly those in the skin, subcutaneous tissues, and muscles, thus shunting blood away from these tissues to those organs where oxygen and metabolites are urgently needed to maintain function (e.g., brain, heart, and kidneys in the case of blood loss). If these reflex sympathetic responses fail to raise the blood pressure sufficiently (in which case the patient is said to be in shock), the vital functions of these organs begin to fail, often catastrophically.

How to Prevent Heart Disease. About 610,000 people die from heart disease each year in the U.S. alone. There are tons of factors that can cause a person to develop heart problems, but most of them come down to poor lifestyle choices. Your body gives you warning signs early on so that you can catch an illness in its early stages or even prevent it altogether and save your life. Here are 10 of the most common red flags that indicate bad heart health. #heartproblems #healthyheart #bodysigns A cough that won't quit 1:38 A persistent cough can be a symptom of all kinds of health issues, and cardiovascular disease is one of them. For instance, a chronic cough that produces a pinkish bloody liquid is very common in people with heart failure. Despite what it sounds like, heart failure doesn't mean that the heart completely stops beating. It just means that a person’s heart isn’t pumping blood as well as it should be. As a result, the body doesn't get enough oxygen since it’s carried to all the tissues by the blood. Nausea and loss of appetite 3:07 A lot of heart disease patients show a lack of appetite, nausea, or both, even if they've had just a couple bites of food. The reason for that is built-up fluid around the liver and intestines that interferes with proper digestion. These symptoms are usually accompanied by abdominal pain, upset stomach, or feeling bloated. In fact, abdominal cramps that come and go in short spurts are extremely common right before a heart attack. Your skin becomes paler or takes on a bluish tint 5:28 Being naturally pale doesn’t necessarily mean you have a heart condition. But sudden paleness can be a result of reduced blood flow due to a heart that’s not pumping blood as effectively as it should be. Shock, which can be caused by any condition that prevents the blood in your body from circulating properly, is the main reason why people who are suffering from a heart attack or heart failure turn pale all of a sudden. Chronic or sudden fatigue 7:02 Fatigue can be one of the main symptoms indicating an impending heart attack. Women are more likely to experience heart-related fatigue than men, with 70% of female heart attack patients reporting that they’d felt extremely tired before their episode. Physical or mental activity isn't the reason for such exhaustion, and it increases by the end of the day if it’s due to a failing heart. It’s really hard for this symptom to go unnoticed. Sometimes it's exhausting just to perform even the simplest tasks, like making the bed or taking a shower. Music: The 126ers - Darkness of My Sun Density & Time - City of Jewels https://www.youtube.com/audiolibrary/music TIMESTAMPS 10. Pain that spreads to the arm 1:01 9. A cough that won't quit 1:38 8. Swollen legs, ankles, and feet 2:25 7. Nausea and loss of appetite 3:07 6. Extreme levels of anxiety 3:47 5. Lightheadedness or fainting 4:26 4. Your skin becomes paler or takes on a bluish tint 5:28 3. Skin rashes or unusual spots 6:20 2. Chronic or sudden fatigue 7:02 1. Increased perspiration 7:45 SUMMARY -If their heart isn’t working properly, a lot of men feel pain in their left arm, while women experience the same pain in either or both arms. -A persistent cough can be a symptom of all kinds of health issues, and cardiovascular disease is one of them. -When your heart isn’t pumping enough blood through the body, fluid from your blood vessels leaks into surrounding tissues. Your lower extremities are the most affected simply due to gravity. -A lot of heart disease patients show a lack of appetite, nausea, or both, even if they've had just a couple bites of food. -People who suffer from extreme anxiety from a very early age or most of their life are more prone to developing coronary heart disease. -Feeling lightheaded and experiencing temporary loss of consciousness, also known in the scientific community as “syncope”, is super common among heart patients. -Sudden paleness can be a result of reduced blood flow due to a heart that’s not pumping blood as effectively as it should be. -People with eczema were found to have a 48% chance of suffering from high blood pressure and a 29% possibility of having high cholesterol. -Sometimes it's exhausting just to perform even the simplest tasks, like making the bed or taking a shower before a heart attack. -People experience flu-like symptoms, have clammy skin, and sweat regardless of the air temperature or physical exertion.

Contribution of the Arterial System and the Heart to Blood Pressure during Normal Aging - A Stimulation Study By: By Maksuti E, Westerhof N, Westerhof B, Broomé M, Stergiopulos N [CC BY 4.0] Article: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4920393/ Conclusion: This study shows that both the arterial system and the heart contribute to the blood pressure changes in normal aging and quantifies the arterial and cardiac contributions to blood pressure over a wide age range (20 to 80 years). The changes in arterial properties initiate a systolic pressure increase, which in turn initiates a cardiac remodelling process that further augments the systolic pressure and mitigates the decrease in diastolic pressure. The close agreement between simulated pressure changes and published data supports the idea that the approach presented may be applicable to the analysis of arterial and cardiac changes in both health and disease. More data on arterial and cardiac function in aging would help future refinement of the model and application to other conditions.

Congestive Heart Failure Congestive heart failure is sometimes simply called “heart failure”. It is the leading cause of hospitalization in people over 65 affecting about 670,000 Americans annually. Currently nearly 6 million persons in the United States have a diagnosis of heart failure. Heart failure doesn’t mean that the heart has “stopped” working, but, that its pumping ability is weaker than normal. With heart failure, the pressure in the heart increases because the blood moves through the heart and body at a slower rate. As this happens the chambers of the heart may slowly change by stretching to hold more blood to pump through the body or by becoming stiff and thickened. This helps to keep the blood moving for a while, but eventually the heart muscle walls become weakened and then unable to pump efficiently. The next thing that usually happens is the kidneys respond by causing the body to retain fluid (water) and salt. The body becomes congested as this fluid builds up in the arms, legs, ankles, feet, lungs, or other organs. This condition is described now as “congestive heart failure”. Congestive Heart Failure (CHF), is a usually a chronic illness that affects the chambers of the heart. There are four chambers in the heart. The upper half of the heart is known as the atria which is divided into 2 sides, the left and the right side, and the other lower half is the left and right ventricles. A healthy normal heart is a strong, muscular pump somewhat bigger than a clenched hand. It pumps blood continuously through the circulatory system. The right atria takes in deoxygenated blood from the systemic circulation and sends it back out to the lungs through the right ventricles where the blood gets to be oxygenated. Oxygenated blood leaves the lungs, travels to the left atrium, then on to the left ventricles, which pumps it to the systemic circulation to provide oxygen and nutrient rich blood to the different organs and tissues. The heart pumps blood to the lungs and to all the body’s different organs and tissues by a sequence of highly organized contractions of the four chambers. For the heart to function properly, the four chambers must beat in an organized way. With heart failure, the heart muscles becomes weak for various reasons, making the heart slowly lose the capacity to pump enough blood throughout the body to meet the body’s demand of oxygen and nutrients. As the heart’s pumping turns out to be less effective, blood may back up into different zones of the body. Fluid may build up in the lungs, liver, gastrointestinal tract, and the arms and legs. Thus, it is called Congestive Heart Failure (CHF). There are two fundamental issues in congestive heart failure: Systolic dysfunction – when the heart can’t pump enough blood supply to meet the body’s demand. Diastolic dysfunction – when the heart cannot accept all the blood being sent in. Sadly, many people suffer with both systolic and diastolic heart failure. Causes: CHF is often a chronic condition, yet it may come on all of a sudden. It can be brought about by various heart problems. The condition may affect just the right side or just the left half of the heart. But more often, both sides of the heart are involved. The most common causes of CHF are: Coronary artery disease (CAD) – a condition wherein cholesterol and other types of fatty substances blocks or narrows the arteries that supply the heart with blood. This can weaken the heart muscle over time or suddenly. High blood pressure – persistent/not well controlled/untreated hypertension forces the heart to pump against higher pressure, causing the heart muscles to weaken over time. Less common causes: Heart valves disease – heart valves that are not properly working by being too narrow or leaky Endocarditis or myocarditis – infection causing inflammation of the heart muscles Arrhythmias Heart attack Excessive use of alcohol or drugs Diabetes Being obese or overweight High blood cholesterol Heart muscle disease of unknown cause Kidney conditions that increases blood pressure and fluid buildup Other medical conditions such as thyroid diseases or anemia

Hypertension nursing NCLEX review about pathophysiology, treatment, nursing interventions, and pharmacology. Hypertension is the amount of resistance of blood pumping through the body/arteries. It affects organ systems of the body such as the cardiovascular, brain, kidneys, and eyes. A normal blood pressure is less than 120/80 (systolic blood pressure/diastolic pressure). Nursing interventions include assessing hypertension risk factors, obtaining blood pressure readings, evaluating medication compliance, and monitoring for side effects of pharmacological medications used for hypertension.

The low quality of the food will make your body have something damaged, and it won’t work properly. Consumption of large amounts of sodium is the key reason for poor health and serious problems. Because of this, you need to avoid these 16 foods and keep your health on point . Table salt: in case you are consuming more salt from that it is necessary, you will have problem with your vision and circulations. When you have a problem with the circulation your heart, kidneys and brain are in danger. Fast food French fries: when you are consuming French fries, you are putting your health on a risk. Pop: a lot of studies showed that sugar is found in sodas and similar products. These drinks will cause hypertension. Liquor: a lot of studies showed that consuming alcohol will decrease the blood supply levels. Red meat: this ingredient will increase the risk of making health problems and impair the veins function. Processed meat: Many health problems for the heart arrive from meat products such as bologna, wieners, bacon, frankfurter and other pre-prepared meats. To avoid hypertension and keep your heart health on point, steer clear from processed meats and try consuming low-salt meat such as chicken, turkey bosom or incline hamburger. Pickles: we know that they are very low in calories, but they are high in sodium. This is something which we may say it is made of sodium. Sugar: sugar is not used at all, especially the ne which is processed. Doughnuts: these are very delicious, but they are full with calories which will make a damage on our organism. Margarine: it is used in everyday cooking, but it is so bad and unhealthy which everyone can see it. Canned Chicken Noodle Soup: Chickens are very bad, especially in the soups. No matter that is the easiest and the fastest meal, it is not healthy and it is not good. Canned biscuits are quite changed before becoming what we see in the stores. This means that they are full of processed substances and seasoned excessively. Check up the names of the ingredients on the label when buying biscuits and make sure they do not contain any hydrogenated oils. Also, keep in mind the sodium content. Ramen noodles: This is shockingly but one bundle of ramen noodles has 14 g fat and 1580 mg sodium. Accommodation foods like frozen pot pies: One sweet pie contains around 1300-1400mg of sodium and around 35 g of fat. This is far beyond the allowed daily limit. So, steer clear of these seemingly healthy desserts for good. Pizza: No matter it is the best meal ever and everyone are in a mood to eat pizza, it is very unhealthy and you need to take care of you. In addition we are going to present you the ingredients which are going to lower your blood cholesterol. Natural products we recommend for reducing hypertension are, beans, peas, veggies, grain oats, rice, pasta, and breads. You also need to eat sweet potatoes (squashed or prepared), spinach, lima beans, bananas, oranges (and squeezed orange!), and tomatoes.

This animation focuses on the renin angiotensin aldosterone system (RAAS), a classic endocrine system that helps to regulate long-term blood pressure and extracellular volume in the body. Many aspects of cardiovascular disease progression can be directly linked to the RAAS system. Mechanisms such as vascular inflammation, generation of reactive oxygen species and alterations of endothelial function are all known to play a role in atherosclerosis.

Are High Blood Pressure Medications Healthy For You? Besides lowering blood pressure, all antihypertensive drugs can produce undesirable side effects. This is not surprising since they alter basic body functions not only in the blood vessels. But in the nervous system and kidneys as well. Since they alter basic functions, all drugs must have several effects. Even if a drug acts on only one type of molecule in the body. Because all systems in the body are interconnected it certainly will produce other effects. Some examples. By limiting the ability of the heart to beat faster. Beta blockers reduce the ability of a person to exercise. And thiazide diuretics produce changes in the composition of body fluids. Including blood cholesterol. So by altering basic bodily functions. Drugs affect the ability of the body to adapt to different situations. Typical side effects of some of the more commonly used antihypertensive drugs include. Urinary loss of potassium, fatigue, gastric irritation, nausea, vomiting, abdominal cramps, diarrhea, dizziness, headache, rash, weakness, nasal congestion, impotence, congestive heart failure, mental depression, short-term memory loss, and in the case of beta blockers, reduction of ability to exercise. In fact, the reduction in blood pressure is associated not with improvement in the function of the cardiovascular system. But rather with a suppression of cardiac function. Sometimes other drugs are added to treat these side effects. In addition, antihypertensive drugs may adversely affect other diseases. How common are complications due to these drugs? Well, in a government-sponsored study of over five thousand patients being treated. With drugs for high blood pressure. It turned out that the drug-treated group had fewer strokes. But a worse outcome in coronary disease. In fact, after ten years of treatment. Death due to coronary heart disease was significantly greater in the drug-treated group than in the untreated group. However, no significant effect upon overall rate of death was observed. Altogether, these studies were seen to justify the assumption. That antihypertensive drug treatment saves lives and reduces fatal and nonfatal complications. Of this threat to health. So in spite of the fact that some physicians had begun to worry about. The increasing number of totally unexpected adverse effects for the last forty-five years. Almost all people diagnosed as having primary hypertension have faced the prospect of a lifetime of treatment with drugs. Subscribe Now And leave a comment below! Thank you for watching!

Why is it so important to keep cholesterol at the normal levels and how to maintain it within the health limits? Cholesterol is a vital, fat-like substance that is contained in each cell of our body, as well as in our blood. Most of the cholesterol is produced by the liver, and the rest is procured through food. Please subscribe, click the bell and watch this video until the end to know the complete information. Cholesterol has extremely important reasons for our body and functions: it participates in the construction of cell membranes and in the formation of sexes and adrenal hormones; without cholesterol, the body can not synthesize vitamin D, which is indispensable to healthy bones, nor produces bile acid, without which fat in the body cannot be processed properly. When an excess of cholesterol accumulates in the body, it can not be broken down and this increases the risks to our health. The main danger is the onset of atherosclerosis, which in turn is the cause of most cardiovascular diseases such as a heart attack for example. The causes of increased levels of cholesterol in the blood are different: hereditary predisposition, chronic liver disease thyroid gland and diabetes. A sure way to maintain a normal cholesterol level is regular testing. Specialists recommend except for total, to monitor still poor (LDL) and good (HDL) cholesterol, as well as triglycerides. It is known that 20 years is the age in which the first examination for determining the values of cholesterol should be done. Revealed in time, increased cholesterol can be overcome and can not lead to serious health problems later. Here are 6 signs that you may have high cholesterol. 1. yellow growths on your eyelids. Did you know that yellowish eyelid can be a sign of high cholesterol? Take a good look at the eyelids, if you notice yellow spots, make a doctor’s appointment, check your cholesterol levels and your heart’s health. Also, do you notice painless yellow growths of the upper and lower eyelids? This phenomenon is called “xanthelasma” and it is a clear indication that you have high blood cholesterol levels. 2. gray-colored ring around your cornea. Often this is a sign of aging, so it should not be a cause for worry. But if you are far from retired, the gray circle around the iris may indicate high cholesterol and blood fat, which very often means a risk of heart attack or stroke. This gray colored ring or lacquer is actually composed of cholesterol that collects in the deeper parts of your cornea. 3. tingling sensation in the hands and feet. The tingling sensation of the hands and feet may indicate a problem in your body. This should be taken seriously because these symptoms can be caused by serious health problems. If the blood vessels are blocked by cholesterol, it is likely that you will feel tingling in your hands and feet, because your peripheral nerves are not getting do enough blood oxygen and nutrients for their proper functioning. 4. pain in the neck and back of the head. Because cholesterol levels that are too high can cause some of your blood vessels to block, it’s very possible that your circulation is obstructed. Such can leave your neck sensitive and deteriorate from time to time. The shoulder can also be felt in the same way. Medical practitioners say that high blood cholesterol levels can also make you have a headache, especially in the back of your head. 5. rapid or pounding beating of the heart. When a person says that she has heart palpitations, she thinks of the inner feeling that her heart beats something different from the usual one. Or, it simply has the awareness of the heartbeat. Most of the time, heart palpitations are harmless and they are often experienced after exercise or engaging in the intense physical activity. Sometimes they are due to anxiety, stress, and the intake of certain drugs. Palpitations may also indicate problems with the cardiovascular system, but and high cholesterol levels are one of them. Clogging the blood vessels due to cholesterol can lead to an accelerated operation of your heart. 6. unhealthy diet and lifestyle. If you eat plenty of fatty foods and avoid fruits and vegetables that contain a lot of fiber if you are a smoker and if you drink alcohol in excessive amounts, if you are overweight and do not exercise regularly, then there is a great chance that your cholesterol level is already high. But sometimes high cholesterol depends on our genes. About 1 in 500 people have a specific genetic mutation that leads to the accumulation of cholesterol in their blood. These people suffer from high cholesterol regardless of their lifestyle. if you suspect that you may have high cholesterol then please start eating a healthy diet and get levels checked out at the hospital.

Let's talk about what is high blood pressure aka hypertension and dangers of have high blood pressure. An optimal blood pressure level is 120/80mmHg or lower, and high blood pressure or hypertension is 140/90 mmHg or higher, whatever your age. The lower your blood pressure the lower your risk of heart attack, heart failure, stroke and kidney disease will be. The top number refers to the amount of pressure in your arteries during contraction of your heart muscle. This is called systolic pressure. The bottom number refers to your blood pressure when your heart muscle is between beats. This is called diastolic pressure. There are no signs or symptoms of high blood pressure which is why it is called the silent killer. High blood pressure can be controlled through lifestyle changes or medication. Some of the dangers of high blood pressure are atherosclerosis, heart failure, stroke, and aneurysms. Atherosclerosis hardening and narrowing of the arteries silently and slowly blocks arteries, putting blood flow at risk. It’s the usual cause of heart attacks, strokes, and peripheral vascular disease -- what together are called cardiovascular disease. What Causes Atherosclerosis? Atherosclerosis begins with damage to the endothelium. It’s caused by high blood pressure, smoking, or high cholesterol. That damage leads to the formation of plaque. When bad cholesterol, or LDL, crosses the damaged endothelium, the cholesterol enters the wall of the artery. That causes your white blood cells to stream in to digest the LDL. Over years, cholesterol and cells become plaque in the wall of the artery. Plaque creates a bump on the artery wall. As atherosclerosis progresses, that bump gets bigger. When it gets big enough, it can create a blockage. That process goes on throughout your entire body. As a result, not only is your heart at risk, but you are also at risk for stroke and other health problems. Atherosclerosis usually doesn’t cause symptoms until middle or older age. But as the narrowing becomes severe, it can choke off blood flow and cause pain. Blockages can also rupture suddenly. That’ll cause blood to clot inside an artery at the site of the rupture. https://www.webmd.com/heart-disease/what-is-atherosclerosis#1 Aneurysms can also occur due to high blood pressure. An aneurysm occurs when an artery’s wall weakens and causes an abnormally large bulge. This bulge can rupture and cause internal bleeding. Although an aneurysm can occur in any part of your body, they’re most common in the: brain aorta legs spleen An aneurysm may occur anywhere in your body, but the most common locations of aneurysms are: Aorta The aorta is the largest blood vessel in the body. It begins at the left ventricle of the heart and travels down the abdomen where it splits off into both legs. The aorta is a common site for arterial aneurysms. Aneurysms in the chest cavity are called thoracic aortic aneurysms. Abdominal aortic aneurysms are the most common type. In rare cases, both the chest and abdomen can be affected by arterial damage. Brain Aneurysms in the brain can be any size. These often form in the blood vessels that lie deep within the brain. They also may not present any symptoms or signs. You may not even know you have. ymptoms of an aneurysm vary with each type and location. It’s important to know that aneurysms that occur in the body or brain generally don’t present signs or symptoms until they rupture. Aneurysms that occur near the surface of the body may show signs of swelling and pain. A large mass may also develop. The symptoms of ruptured aneurysms anywhere in the body can include: bleeding increased heart rate pain feeling dizzy or lightheaded Serious complications from aneurysms can cause death if you don’t get emergency care. https://www.healthline.com/health/aneurysm#symptoms #3 danger of high blood pressure is heart failure or heart attack. More than a million Americans have heart attacks each year. A heart attack, or myocardial infarction (MI), is permanent damage to the heart muscle. "Myo" means muscle, "cardial" refers to the heart, and "infarction" means death of tissue due to lack of blood supply. If you have coronary artery disease, those arteries become narrow and blood cannot flow as well as they should. Fatty matter, calcium, proteins, and inflammatory cells build up within the arteries to form plaques of different sizes. The plaque deposits are hard on the outside and soft and mushy on the inside. When the plaque is hard, the outer shell cracks (plaque rupture), platelets (disc-shaped particles in the blood that aid clotting) come to the area, and blood clots form around the plaque. If a blood clot totally blocks the artery, the heart muscle becomes "starved" for oxygen. Within a short time, death of heart muscle cells occurs, causing permanent damage. This is a heart attack. https://www.webmd.com/heart-disease/guide/heart-disease-heart-attacks#1

Eventually, we realized that these thumping organs serve the vital task of pumping clean blood throughout the body. But how? Edmond Hui investigates how it all works by taking a closer look at the heart's highly efficient ventricle system. Lesson by Edmond Hui, animation by Anton Bogaty.

For more videos please visit: http://www.meritnation.com Have you heard your heart beat? What is the sound like? Yes, it sounds like 'lubb-dubb', 'lubb-dubb'! This sound is produced when the heart produces a pressure when it beats. Now, what causes the beating of the heart? The sequence of events that take place during a single heart beat is known as the Cardiac Cycle. It is not so simple. It is a complex process which involves a sequence of activities and that too within 0.8 sec. The cardiac cycle consists of a systole and a diastole. The cardiac cycle begins with a joint diastole (relaxation of all four chambers of the heart). This is followed by an arterial systole (contraction of left and right atria) stimulated by the generation of an action potential by the Sino-Auricular Node (SA node). As a result of the arterial systole, the blood from the atria drains into the ventricles. The impulse produced by the SA Node is then picked up by the Atrio-Ventricular Node (AV node) and is conducted throughout the ventricles leading to the ventricular systole. During the ventricular systole, the blood from the ventricles is drained into the aorta and the pulmonary artery. This is followed by closing of the AV valves which produces the sound 'lubb' and the closure of the Semilunar valves causes produces the sound 'dub'.

In this Video Lecture, Professor Fink describes the 2 major factors that affect Total Peripheral (Vascular) Resistance [TPR]:  overall degree of arteriolar vasoconstriction &  vascular stenosis [atherosclerotic plaque]. In addition, arterial Blood Pressure is "broken-down" into how the heart [Stroke Volume] is the principal factor that determines the Systolic BP and how TPR is the principal factor that determines the Diastolic BP. Reference is also made to Pulse Pressure, mean (average) arterial BP. Finally, Professor Fink describes the 4 major factors that facilitate Venous Return [VR] of blood in the veins:  the presence of valves;  the "Thoracic Pump" effect of inhaling;  contraction of skeletal muscles &  venoconstriction.
