The thyroid is a gland which is found in the neck, which produces thyroxine, which is an essential hormone for heart functioning, i.e., gives contractility, oxygen supply and oxygen consumption to the heart. So some conditions of the thyroid or hypothyroid or hyperthyroid will cause heart enlargement, which is again not good for the patients. So if a patient has both heart failure and thyroid he should go for the treatment for the thyroid condition so that his heart condition is also improved..

Heart Failure and the Critical Role of Coenzyme Q10 http://kirkspoweraging.com http://prescription2000.com Heart failure is the number one cause of hospital admissions over the age of 65. More than 5.8 million Americans have heart failure in the U.S. and more than 310,000 deaths are caused by heart failure. A recent study in the American Journal of Cardiology: Heart Failure, (JACC Heart Fail. 2014 Dec;2(6):641-9) http://www.ncbi.nlm.nih.gov/pubmed/25282031 showed the following with 100 mg of CoQ10 (ubiquinone form) three times per day or two years in heart failure patients compared to placebo: 44% reduction in cardiovascular mortality 42% reduction in all-cause mortality 45% reduction in the number of hospital stays 29% improvement in the number of patients who had positive changes on their New York Heart Association classification of heart failure severity. These findings if extrapolated to the U.S. population would be 120,000 lives saved each year. Heart failure comes from the heart’s inability to pump blood effectively around the body leading to a "back-up" of fluid and eventual "suffocation" from one's own body fluids. An energy deficit within the heart muscle (mitochondria in the heart cells) can make heart failure worse and progress rapidly. Coenzyme Q10 is a compound made in the body from cholesterol. The use of statin drugs blocks the body's production of cholesterol which can lead to muscle pain and dysfunction, reduced hormone production and possibly cognitive problems. The wide spread use of statins may increase the risk to heart failure because of its effect on CoQ10. Research by cardiologist and heart failure and CoQ10 expert Peter Langsjoen, MD (my interview with Dr. Langsjoen) suggest keeping CoQ10 blood levels above 3.5 ug/ml to optimize heart function in heart failure patients.This will generally take at least 400 mg of CoQ10 as the ubiquinol form (antioxidant form) taken with food, preferably with some fat. Then one should retest for an adequate CoQ10 level above 3.5 ug/ml and adjust accordingly.

Hi, this is Larry Hobbs @ FatNews.com. http://fatnews.com/ https://twitter.com/fatnews Mark Starr, MD tells how his fathers congestive heart failure was cured with desiccated thyroid. Mark Starr is the author of the wonderful book "Hypothyroidism Type 2: The Epidemic". Mark Starr, MD defines Type 2 hypothyroidism. "Type 1 Hypothyroidism I’ve defined as failure of the thyroid gland to produce sufficient amounts of thyroid hormones necessary to maintain normal blood levels of those hormones and normal blood levels of the thyroid stimulating hormone, the TSH, produced by the pituitary gland." "Type 2 Hypothyroidism is peripheral resistance to thyroid hormones at the cellular level." "It is NOT due to a lack of thyroid hormones." "Normal amounts of thyroid hormones and thyroid stimulating hormone (TSH) are usually detected by blood tests." "Therefore, blood tests do NOT detect Type 2 Hypothyroidism." "Type 2 Hypothyroidism is usually inherited however, environmental toxins may also cause or exacerbate the problem." "Type 2 Hypothyroidism has yet to be recognized by mainstream medicine, but is already epidemic." "There is a lot of ‘Subclinical Hypothyroidism’ but I can guarantee you that it is anything but subclinical." Mark Starr, MD 21st Century Pain & Sports Medicine 10565 N.

HORMONES OF HEART, KIDNEY AND GASTROINESTINAL TRACT : HEART : Atrial wall of heart secretes peptide hormone called atrial natriuretic factor ANF which decreases B.P when B.P is increased, ANF is secreted which causes dilation of blood vessels. This reduces B.P. KIDNEY : The juxtraglomerular cells of kidney produce 2 hormones erythropoietinstimulates bone marrow to produce more RBC's and Renin acts on protein angiotensinogen to form angiotersin. Angiotensin raises B.P to increase ultra filtration. Gastro -- intestinal Tract : Endocrine cells present in different parts of gastro intestinal tract secrete 4 major peptide hormones. Gastrin : acts on gastric glands and stimulates the secretion of Hcl and pepsinogen. Secretin -- acts on exocrine pancreas and stimulates secretion of water and bicarbonate ions. Cholecystokinin : acts on both pancreas and gall bladder and stimulates the secretion of pancreatic enzymes and bile juice. Gastric inhibitory peptide : inhibits gastric secretion and motility. Several non endocrine tissues secrete hormones called growth factors. These factors are essential for normal growth and tissues and their repairing / regeneration.

The heart is one of the main muscles of the body that responds to nutrition very quickly. Arrhythmia is a problem with the pacemaker of the heart, a neurological thing that keeps the heart rhythm requires electrolytes. Not having enough electrolyte would create all sorts of abnormal heart rhythm happen in the body. Calcium - it helps contract muscles. Calcium deficiency could cause tetany, muscle twitch and too much calcium could create a rhythm problem with the heart. Vitamin D3 increases the absorption of calcium by 20x in the small intestine and Vitamin K2 helps avoid buildup of too much calcium in the arteries or other soft tissues. Magnesium – Deficient in magnesium could cause leg cramp. Magnesium is involved in relaxation of muscles and it is very important for muscle cramps prevention. Sodium – low in sodium will cause feeling weak and too much sodium would cause high blood pressure. Potassium – The body needs 4,700mg of potassium daily. It is needed for the electrical connectivity of the nervous system and the muscles, it also helps lower blood pressure and lower the pulse rate. Insulin resistance is a condition where the cell can’t absorb the minerals well anymore and it’ll start developing all sorts of issues in the arteries. Plaquing in the arteries develops after a lesion or oxidative problem with the artery wall. Heart attacks occur during a stress events because the adrenal triggers it. The adrenal hormone called adrenaline has one function of vasodilation the coronary artery, the main blood supply to the heart itself. Vitamin B1 is really important in preventing the heart from enlarging. Respiratory and breathing problems will occur when you are deficient in vitamin B1. Some of the B vitamins helps the arteries constrict and some helps with vasodilation.

Serelaxin, a synthetic version of the naturally occurring hormone human relaxin-2, has improved acute heart failure symptoms in clinical trials. Considered to be the first treatment breakthrough for acute heart disease in two decades, the drug increases blood flow throughout the body, which helps a poorly functioning heart work more effectively. It is also an anti-inflammatory, which means it can help prevent the damage heart failure does to the kidneys, liver and heart.

Heart failures can be due to an inability to PUMP effectively during systole - SYSTOLIC heart failure, or inability to FILL properly during diastole - DIASTOLIC heart failure. Heart failure can be right-sided or left-sided . In systolic heart failure, ventricular contraction is compromised. This may be caused by any condition that weakens the heart muscle: - Coronary artery disease/Ischemic HD: - Dilated cardiomyopathy - Hypertension: - Valvular heart disease: Damage to the valves, such as stenosis The effectiveness of ventricular contraction is measured by the EJECTION fraction. The normal range of the ejection fraction is between 50 and 70%. In systolic heart failure, it drops below 40%. In DIASTOLIC heart failure, the ventricle is filled with LESS blood. This may be because it is smaller than usual, or it has lost the ability to relax. The ejection fraction may be normal, but the blood output is reduced. The ejection fraction is therefore commonly used to differentiate between SYSTOLIC and DIASTOLIC dysfunction. Examples of conditions that can lead to diastolic heart failure include: - Hypertrophic cardiomyopathy - Restrictive cardiomyopathy: - Hypertension Regardless of being systolic or diastolic in nature, left-sided heart failures share a common outcome: LESS blood pumped out from the heart. As a result, blood flows back to the lungs, where it came from, causing CONGESTION and INCREASED pulmonary pressure. As this happens, fluid leaks from the blood vessels into the lung tissue, resulting in PULMONARY EDEMA, a hallmark of left-sided heart failure. Accumulation of fluid in the alveoli IMPEDES the gas exchange process, resulting in respiratory symptoms such as shortness of breath, which worsens when lying down, and chest crackles. RIGHT-sided heart failure is most commonly caused by LEFT-sided heart failure. This is because the INCREASED pulmonary pressure caused by left-sided heart failure makes it harder for the right ventricle to pump INTO the pulmonary artery. This results in SYSTOLIC dysfunction. In compensation, the right ventricle grows thicker to pump harder, which reduces the space available for filling, eventually leading to DIASTOLIC dysfunction. Other common causes of right-sided heart failure include chronic lung diseases which also raise pulmonary blood pressure. As the right ventricle pumps out less blood, the blood, again, backs up to where it came from, and in this case, the SYSTEMIC circulation. This results in abnormal fluid accumulation in various organs, most notable in the feet when standing, sacral area when lying down, abdominal cavity and liver. The fluid status can be assessed by examining the distension level of the jugular vein. Heart failure is usually managed by treating the underlying condition, together with a combination of drugs. ACE inhibitors, beta blockers are used to reduce blood pressure in patients with systolic dysfunction. Diuretics are used to reduce water retention.

3D Medical Animation, This is one of ASK Visual Science most complex animations to date. With a total runtime of over 8 minutes across three modules, the program incorporated over 50 separate models, from the molecular (Angiotensin I, BNP, Endothelin), to the microscopic (red blood cells, platelets, endothelial cells), to whole organs (heart, lungs, kidney, liver, vascular system) and even a whole body. Creating, managing, and animating all of these digital assets into a coherent program with a strong narrative using a team of 4 modelers and animators working concurrently - was a challenge. Our client also had a specific tradeshow in mind to premiere the final movie, which was only 12 weeks from project initiation and gave us a fixed deadline. We managed to bring the whole program in on time and on budget - an innovative achievement.

Have a question? Send it to: email@example.com 04:45 -- Nerve regeneration & pain. 10:53 - Youtube and Facebook Birthday wishes. 13:22 - Georgia -- I have two questions for you. The first one is, can a person regain lost memories by being on a raw vegan lifestyle? The second question is about drinking water. Marcie told me I should submit this question to you. In your books you say that distilled water or using R/O system is best and yet they both have no minerals or anything in them. They are basically dead. I drank distilled water only for several years thinking that this was better and easier on my Kidneys. She suggested I drink spring water and that is what I am doing now. Do you feel one is better than the other? 25:00 - Mark -- Happy Birthday Dr. Morse! I wish you endless, cool out of body travels and awesome experiences in many different realities. I can't thank you enough from the bottom of my heart! 25:11 - Malcolm -- I have been having heart problems for around 3 years now - Congestive Heart Failure. I have been admitted to the hospital twice with breathing difficulties, &shortness of breath. I get heart palpitations and high blood pressure. My doctor has now referred me to a heart specialist here in the UK. I have been told that I may need to have a pacemaker fitted, and I'm not happy about that. I would rather go a natural route for healing. Also, my stomach bloats and fills with gas like a basketball, I was given Omeprazole for that. Could you please give me some advice on what herbs I should order from your site? 30:06 - NJanf -- Can you explain why some blue eyes maintain the blue color, even when the person is extremely toxic, while some people will have their blue eyes turn brown within a few years of birth? 32:01 - FlyingWithHorsesUK - I hope that you are all well! I'm still loving your videos & thank you for inspiring so many people to keep reaching ever higher into nature's realm of health & goodness! I'm hoping you can help provide an alternative to the medical way of 'treating' a tooth abscess, as their first port of call is always antibiotics followed by a root canal or extraction. As this is such a painful infection right on the nerve, is there a fast acting remedy which can be used for this alongside the all-important detox herbs & raw fruit diet? Medics remove the nerve after an abscess but I am sure the nerve can be regenerated... do you have any experience with healing this painful infection?

Edema is another feature that is tissue fluid, fluid around the cells in various tissues and this usually occurs in the dependant parts and body cavities when you are walking about that means around your ankles when you are lying in bed that means in your limbo sacral region so you must not expect patients lying in bed to show much ankle edema because they are likely to have this in their dependant parts and the most dependant part in bed is the lumbar Sacral region/ Fluid can also occur in the body cavities so that the chest can fill up a pleural effusion fluid in the pleural cavities outside the lungs but next to the chest wall that can occur in heart failure the abdomen can swell because of the retained fluid Ascites, and sometimes very rarely fluid retained in the pericardial cavities Now the cause of the edema is perhaps we should say a word or two about, because you may say to your self its just because the venous pressure rises the cappliiary pressure in the skin rises and fluid exudes out as starling said it would starlings law but it is not as easy and that is the important reason why patients with HF get edema is that they have renal abnormality the circulation to the kidneys is impaired and if you remember the kidneys respond to that by secreting excess aldesterone which is a very potent sodium and therefore fluid retaking hormone and therefore patients who develop impaired blood flow to the kidneys send out a message saying for goodness sake retain fluid because we are suffering and they overdo the job and the patient becomes oedematous as a result so is not just a question of raised venous pressure Patients may notice not the swelling but the end result, they may notice that they are not passing as much urine we call that oliurea and if you were to ask Mrs smith are you passing less water and the answer will come yes they are passing less water because they are retaining it in the tissues, and the other interesting thing that happen is that they tend to pass more water at night so they have noturia there is a reversal of the normal rhythm which makes you pass more water in the day than at night but in heart failure the opposite occurs

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

Mark Starr is the author of the wonderful book "Hypothyroidism Type 2: The Epidemic". Mark Starr, MD defines Type 2 hypothyroidism. "Type 1 Hypothyroidism I’ve defined as failure of the thyroid gland to produce sufficient amounts of thyroid hormones necessary to maintain normal blood levels of those hormones and normal blood levels of the thyroid stimulating hormone, the TSH, produced by the pituitary gland." "Type 2 Hypothyroidism is peripheral resistance to thyroid hormones at the cellular level." "It is NOT due to a lack of thyroid hormones." "Normal amounts of thyroid hormones and thyroid stimulating hormone (TSH) are usually detected by blood tests." "Therefore, blood tests do NOT detect Type 2 Hypothyroidism." "Type 2 Hypothyroidism is usually inherited however, environmental toxins may also cause or exacerbate the problem." "Type 2 Hypothyroidism has yet to be recognized by mainstream medicine, but is already epidemic." "There is a lot of ‘Subclinical Hypothyroidism’ but I can guarantee you that it is anything but subclinical." Mark Starr, MD 21st Century Pain & Sports Medicine 10565 N.

Hello Everyone, here is a Cardiovascular lecture on Congestive Heart Failure made easy to understand to help aide in your study sessions. I have gathered all of the important information from my Med- Surg Book (Brunners and Suddarth 12th edition) and NCLEX review (Saunders 6th edition) that will prepare you for your nursing test whether it is for school or NCLEX. Part 2 of this lecture will be located under the Pharmacology section as it continues with cardiac meds that will further explains MOA, side effects, etc. Here are some Extra information that may help and guide you... Two major types of HF are identified by assessment of left ventricular functioning, usually by echocardiogram. The more common type is an alteration in ventricular contraction called systolic heart failure, which is characterized by a weakened heart muscle. The less common type is diastolic heart failure, which is characterized by a stiff and noncompliant heart muscle, making it difficult for the ventricle to fill. An assessment of the ejection fraction (EF) is performed to assist in determining the type of HF. EF is calculated by subtracting the amount of blood present in the left ventricle at the end of systole from the amount present at the end of diastole and calculating the percentage of blood that is ejected. A normal EF is 55% to 65% of the ventricular volume; the ventricle does not completely empty between contractions. The EF is normal in diastolic HF but severely reduced in systolic HF. Although a low EF is a hallmark of systolic HF, which is the most common type of HF, the severity of HF is frequently classified according to the patient’s symptoms. Pathophysiology: Systolic HF results in decreased blood volume being ejected from the ventricle. The decreased ventricular stretch is sensed by baroreceptors in the aortic and carotid bodies. The sympathetic nervous system is then stimulated to release epinephrine and norepinephrine. The purpose of this initial response is to increase heart rate and contractility and support the failing myocardium, but the continued response has multiple negative effects. Sympathetic stimulation causes vasoconstriction in the skin, gastrointestinal tract, and kidneys. A decrease in renal perfusion due to low CO and vasoconstriction then causes the release of renin by the kidneys. Renin promotes the formation of angiotensin I, a benign, inactive substance. Angiotensin- converting enzyme (ACE) in the lumen of pulmonary blood vessels converts angiotensin I to angiotensin II, a potent vasoconstrictor, which then increases the blood pressure and afterload. Angiotensin II also stimulates the release of aldosterone from the adrenal cortex, resulting in sodium and fluid retention by the renal tubules and stimulation of antidiuretic hormone. These mechanisms lead to the fluid volume overload commonly seen in HF. Angiotensin, aldosterone, and other neurohormones (eg, endothelin, prostacyclin) lead to an increase in preload and afterload, which increases stress on the ventricular wall, causing an increase in the workload of the heart. A counterregulatory mechanism is attempted through the release of natriuretic peptides. Atrial natriuretic peptide (ANP) and B-type (ie, brain type) natriuretic peptide (BNP) are released from the overdistended cardiac chambers. These substances promote vasodilation and diuresis. However, their effect is usually not strong enough to overcome the negative effects of the other mechanisms. As the heart’s workload increases, contractility of the myocardial muscle fibers decreases. Decreased contractility results in an increase in end-diastolic blood volume in the ventricle, stretching the myocardial muscle fibers and increasing the size of the ventricle (ventricular dilation). The increased size of the ventricle further increases the stress on the ventricular wall, adding to the workload of the heart. One way the heart compensates for the increased workload is to increase the thickness of the heart muscle (ventricular hypertrophy). However, hypertrophy results in an abnormal proliferation of myocardial cells, a process known as ventricular remodeling. Under the influence of neurohormones (eg, angiotensin II), large myocardial cells are produced that are dysfunctional and die early, leaving the other normal myocardial cells to struggle to maintain CO. The compensatory mechanisms of HF have been called the “vicious cycle of HF” because the heart does not pump sufficient blood to the body, which causes the body to stimulate the heart to work harder; thus, the heart cannot respond and failure becomes worse. Diastolic HF develops because of continued increased workload on the heart, which responds by increasing the number and size of myocardial cells (ie, ventricular hypertrophy and altered cellular functioning). These responses cause resistance to ventricular filling, which increases ventricular filling pressures despite a normal or reduced blood volume.

Hyperparathyroidism nursing review lecture of hyperparathyroidism symptoms, pathophysiology, causes, and nursing interventions. Hyperparathyroid is the excessive production of parathyroid hormone by the parathyroid gland. This parathyroid disorder leads to hypercalcemia and hypophosphatemia. Signs and symptoms of hyperparathyroidism include bone fractures, renal calcui, constipation, excessive urination, nausea, vomiting, epi-gastric pain, EKG changes (shorten QT interval) and lab values that reflect hypercalcemia and hypophosphatemia. Causes of this parathyroidism include primary hyperparathyroidism and secondary hyperparathyroidism. Primary hyperparathyroidism is caused by a malfunctioning parathyroid due to an adenoma, hyperplasia, or cancer. Secondary hyperparathyroidism is caused by a disease that affects the function of the parathyroid such as chronic kidney disease, hypocalcemia, and vitamin-d deficiency. Nursing interventions include monitoring vitals, straining urine for possible renal calcui, monitoring EKG, and administering medications as prescribed by the doctor. The goals of medication treatment in hyperparathyroidism are to decrease the calcium and PTH levels, and maintain hydration.

In the body, most calcium is located in bones, only about 1% is in the blood and extracellular fluid. The amount of calcium in circulation is regulated by 2 hormones: parathyroid hormone, PTH, and calcitriol. When serum calcium level is low, PTH is UPregulated. PTH acts to PROMOTE calcium release from bones and REDUCE calcium loss from urine. At the same time, it stimulates production of calcitriol, which promotes absorption of calcium in the small intestine while also INcreases RE-absorption in the kidney. Together, they bring UP calcium levels back to normal. The REVERSE happens when calcium level is high. This feedback loop keeps serum calcium concentrations within the normal range. HYPOcalcemia refers to ABnormally LOW levels of calcium in the blood and is generally defined as serum calcium level LOWER than 2.1 mmol/L. Because the total serum calcium includes albumin-bound and free-ionized calcium, of which only the LATTER is physiologically active, calcium levels must be corrected to account for albumin changes. For example, DEcreased albumin levels, such as in liver diseases, nephrotic syndrome, or malnutrition, produce LOWER serum calcium values but the amount of FREE calcium may STILL be normal. On the other hand, in conditions with high blood pH, albumin binds MORE calcium; leaving LESS FREE-ionized calcium in the serum while the total calcium level may appear normal. The most common cause of hypocalcemia is PTH deficiency resulting from DEcreased function of the parathyroid glands, or HYPOparathyroidism. HYPOparathyroidism, in turn, may be caused by a variety of diseases and factors. These include: - accidental removal or damage of the parathyroid glands during a surgery - autoimmune disorders - congenital disorders: mutations that set the “normal calcium levels” to a lower value - other genetic disorders that produce underdeveloped or non-functional parathyroid glands - magnesium deficiency Other causes of hypocalcemia include low vitamin D intake/production, and excessive loss of calcium from the circulation such as in kidney diseases, tissue injuries or gastrointestinal diseases. While chronic moderate hypocalcemia may be Asymptomatic, ACUTE and severe hypocalcemia can be life-threatening. Most symptoms of acute hypocalcemia can be attributed to the effect it has on action potential generation in neurons. Because extracellular calcium INHIBITS sodium channels, and consequently DEpolarization, REDUCED calcium level makes it EASIER for depolarization to occur. Hypocalcemia therefore INCREASES neuronal excitability, causing neuromuscular irritability and muscle spasms. Early symptoms often include numbness and tingling sensations around the mouth, in the fingers and toes. As the disease progresses, muscle spasms may manifest as tetany, wheezing, voice change, and dysphagia. Seizures may occur in severe cases. Effects of hypocalcemia on cardiac function include long QT interval due to prolonged ST fragment, congestive heart failure and hypotension. Acute hypocalcemia should be treated promptly with intravenous calcium. Chronic hypocalcemia is usually treated with oral calcium and possibly vitamin D supplementation.

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.
