Know more about your Heart!
Heart works for many years without tiring and rests between beats. It gets a very good supply of blood so that it has a lot of energy available. It is made of a special kind of muscle that is very strong and is called cardiac muscle. It can contract quickly and strongly without getting tired. The muscle cells in the heart seem to run together so that they look like one giant cell. This allows the heart to “pull together.” The heart is made up of two halves because it is really two pumps connected together. Each pump has arteries taking blood away and veins bringing it back.
One of the pumps sends the blood to the lungs. The blood picks up oxygen there. When this blood returns to the heart, the second pump sends it out through arteries to the cells in the body. It picks up carbon dioxide, a waste product of the cells. When you cut, bleeding comes from capillaries and blood soon form clot. Sometimes people are born with blood that cannot form clot. They have a disease called hemophilia. For them even a small cut is dangerous. Each half of the heart has two kinds of chambers. There is a thin-walled chamber at the top. It is called the atrium, from the Latin word for “entrance hall.” The blood enters the atrium first. Under the atrium is a ventricle, which means “little hollow.” It has thick, muscular walls. There are four chambers in the heart : a right atrium, a right ventricle, a left atrium, and a left ventricle.
During its trip through the arteries, the blood delivers oxygen to the rest of the body. It passes to the liver. In the liver, it picks up glucose. The glucose is supplied to the body’s cells. And the body’s cells give their wastes to the blood. This exchange of materials always occurs through the capillaries. The capillaries then join into small veins, which join into larger veins, and so on. The largest veins bring the blood back to the right atrium. By now, the oxygen is all used up and the whole cycle is gone through once more.
The valves in the veins of the legs are especially important Blood must flow up the legs toward the heart, against the force of gravity, which pulls the blood downward. The valves in the veins keep the blood from falling back down. This is one reason why walking is good exercise. The working of the leg muscles keeps the blood moving in the leg veins. When a person stands a lot and has little exercise, the blood may not move fast enough. The blood may collect in the veins and cause them to swell up.
If a vein is cut, the bleeding that results can be controlled without much trouble. Blood flow from a vein is slow. And the thin walls of a vein can be easily pressed shut. But when an artery is cut, that is dangerous indeed. The blood gushes out forcefully with each heartbeat, and it is hard to close the artery’s muscular walls.
Five Steps Towards A Healthy Heart
Posted on May 9th, 2009 by guideheartdisease
The heart is an extraordinary organ in our body. Our life and death depend on our heart. Our live begins when we have our first heartbeat and our life ends when the beating of our heart stops. People may argue the level of importance our heart in our body as compared with other organs of the body, but none can argue the fact that we need our heart to live. That is why we need to take extra good care of our heart.
The first step to a healthier heart is to exercise regularly. Even the littlest amount of exercise can help us to maintain the health of our heart. This is because regular exercises play an important role in preventing heart or coronary diseases. Exercises give our heart the stamina it needed to pump blood into our veins.
If you have a poor heart, do some simple exercises but do take care to not over-strain your heart. Simple exercises like a long and leisurely walk at the beach or the park can really help you to be in a better physique that will ultimately influences the health of your heart.
The second step that you can take to take care of your heart is to stop smoking or to not start the bad habit of smoking. Smoking is bad for your heart because smoking can increase the risks of hypertension, heart and coronary diseases and even strokes. Not many people realize that smoking is also the key cause to cardiovascular diseases. This is because smoking can actually cause the fatty substances to build up in our arteries. These built up fats will eventually block our arteries and cause us to have a heart attack or a stroke.
To prevent yourself from getting a heart disease, you must also limit your alcohol intake to the minimum level. This is because, just the same as smoking, alcohol consumption will have harmful effects on your arteries that will one day lead to heart attack and stroke.
Alcohol consumption will also lead to increased risks of hypertension. Alcohol when consume in moderation will have a good effect on our body. The alcohol raises the level of the HDL, which is the good cholesterol and thus will help to protect us from heart diseases. But only when consumed in moderation.
The fourth step to preventing heart diseases is to have a good and healthy diet routine. Eating healthily can not only maintain the health of our heart, it can also lower our cholesterol level and also our blood pressure. To have a good and healthy diet plan, do make sure to include a lot of greens or vegetables into your diet. Do not forget to consume the minimum portion of fruits for your daily intake to ensure that your body have the right level or vitamins and minerals.
The last step that we can follow to make sure we have got a good and healthy heart is to keep and maintain a healthy weight. People suffering from obesity have more chances of contracting heart diseases than the people who have normal body mass indexes.
There were studies that showed cases where heart diseases were linked directly to heart failures. So obese people should really try their best to lose some weight and those on the edge to obesity should take care of their weight as to not have heart problems in the future.
Heart diseases are scary but they are treatable. And if we take enough prevention measures, there might not even be any need for treatments. Do the right thing, and start your prevention steps now.
Heart Health Care with Oral Chelation
Posted on May 4th, 2009 by guideheartdisease
The rapid increase of moralities due to heart disease is a direct result of our fast-paced, modern lifestyle. Protecting yourself from cardiovascular ailments requires several lifestyle adjustments such as; reducing your intake of fatty foods and tobacco, while increasing your intake of whole foods, nutritional supplements and daily exercise. Oral chelation is also worth considering as a way to improve your health.
It’s easy to say: “eliminate all of the activities and foods which present a health risk.” The fact is we are human and a stringent routine is not the easiest to maintain. In addition there are certain aspects of our environment which are beyond our control that have a severe impact on our health. Two of the most outstanding are environmental pollutants found in the air and water as well as chemicals used in the processing of food products.
Because of this it is even more important to keep abreast of the developments that can help you maintain an optimal state of health. Prevention of heart disease is possible by using chelation therapy along with modifying your daily lifestyle choices. Oral chelation formulas provide an uncomplicated method to address the number one cause of heart disease: calcified plaque which results in hardening of the arteries. For individuals who prefer professional chelation therapy treatments, the intravenous form can be administered by your physician.
Medical doctors use intravenous chelation therapy to extract harmful toxins from the bloodstream to prevent them from blocking the arteries of the heart. The hardening of the arteries and high blood pressure are the leading cause of heart disease. Each intravenous chelation therapy session requires about three hours of time complete. However the alternative form of this therapy is oral chelation whose formulas are just as effective as intravenous treatments administered by your physician.
The gold shield elite company produces an oral chelation formula with the same strength of intravenous preparations. the “Original Oral chelation” formula differs from the intravenous form only in its convenience of use: it’s taken daily in addition to your vitamin supplements as opposed to three hour visits to your doctor’s office.
The formulation used in oral chelation therapy contains a wide range of natural ingredients that support the chelating agents such as; bee pollen, vitamin C, honey, vitamin B12. In addition to EDTA (EthyleneDiamine Tetra-acetic Acid) which is one of the most powerful synthetic amino acids there are plans sterols are in antioxidants in a supporting role to assist detoxification. It is a safe, proven way to inexpensively reduce your risk of heart disease and lower your cholesterol level.
STRUCTURE AND FUNCTIONING
The heart is divided into four main chambers : each one is a bag of muscles with walls that are able to contract in order to push blood out. Each wall’s thickness varies according to the amount of work it does. The walls of the left ventricle are the thickest because it does most of the pumping.
The chambers on either side of the heart are arranged in pairs. Each side has an atrium, with thin walls, to receive blood from the veins. The atrium pumps blood into a thicker-walled ventricle, through which the blood is pumped into a main artery.
The heart is involved in two separate circulatory functions. Oxygen-rich blood is pumped from the heart into the body through the aorta. This is called systemic circulation. When this blood is returned to the heart, after the cells have absorbed all the oxygen and nutrients, the heart pumps the blood into the lungs through the pulmonary artery. Here, the oxygen supply is replenished and the blood is returned to the heart. This is known as pulmonary circulation.
Pulmonary veins bring the newly-oxygenated blood from the lungs to the heart. It reaches the left atrium, which contracts and pushes the blood out through the mistral valve into the left ventricle. Then the left ventricle contracts. The blood moves through the open aortic valve into the aorta, and on to the system of arteries and capillaries, and into the tissues.
What is a Heart Murmur?
Heart Murmurs are those unusual sounds that are associated with the heart beat. These sounds are sometimes heard by the person himself or when diagnosed by a doctor. They are the indications of cardiac abnormality and should be very carefully handled and care should be taken. Take a look
Are they signs of Heart Disease?
Yes, they are the signs of some very serious disorder and have to be very carefully handled and taken care of. If we take a look on how they sound, we get to know that they produce sounds from very faint to loud sound which can be heard by the patient himself. The normal sound caused due to the opening and closing of the valves are strictly matched with the heart sounds of the patient and then diagnosed for this disease if the heart sound is abnormal. Also they are the signs of an impending heart disorder.
How are they produced?
Normally these irregular heart murmurs are caused due to turbulent blood flow from the heart. If we look at the two types of Heart Murmurs, Innocent and abnormal heart murmurs, the innocent one is harmless and does not cause any major problem to the body. They may be present in children and the sounds continue to remain the same throughout life. Normally those with Innocent Heart Murmurs are not susceptible to any kind of disease.
The abnormal heart murmurs are common with those people who have a history of heart disorders in their life and provide a risk of suffering from a cardiac arrest. Normally these sounds are loud and can e heard very easily. Also these sounds mean a heart disorder where the arteries which supply blood to the heart are clogged with fatty deposits or they are narrowed down. So if the patients are diagnosed with this form of heart murmur, they may need immediate hospitalization.
What to do?
Immediately after the patient is diagnosed with the irregular heart murmurs, the patient should not waste time and he should be immediately hospitalized to take care of the disease. As we have seen the causes for these heart murmurs can be very different and hence the diagnosis of the disease causing the murmur is required. Once the main disease is recognized then the heart murmurs can be controlled to some extent.
There is no treatment for the innocent heart murmurs as they are natural and not a disease condition. Also the patients need not worry about the innocent type as they are harmless. Correct diagnosis and the right treatment will reduce the extent of pressure the heart is facing and also give better standard of living. So it is in our hands to preserve our health!!!
EFFECTS OF CHOLESTEROL
When the cholesterol intake is more, some of the extra cholesterol in the blood returns to the liver where it is broken down and then secreted as bile by the gall bladder. But when cholesterol levels rise too high, they can lead to fatty deposits called PLAQUE, which clog arteries and thus set the stage for heart diseases and strokes. Just a small clot in a plaque clogged coronary artery is enough to arrest blood flow to the heart and thereby cause a heart attack.
Recently a lot of interest has been generated in trying not only to retard the progression but also attempt to regress and even reverse the atherosclerotic process. Current research is focussed mainly on the atherosis reversion and the sclerotic components has received less attention.
The atheromatous plaque is constituted mainly (60% of dry weight) by cholesterol, cholesterol esters and phospholipids. The bulk of lesion cholesterol (except for crystalline cholesterol monohydrate and cholesterol trapped by altered connective tissue) exchanges with plasma cholesterol. Therefore, if plasma cholesterol levels are lowered, reduction of plaque cholesterol should occur and the lesion should regress. However, total regression of atheromatous plaque is not possible because cholesterol monohydrate crystal is resistant to mobilization. The fibrous cap of the plaque and abundant fibrous stroma constitute additional physical barriers for the egress of the extra cellular cholesterol. The regression of early uncomplicated plaques will be easier than regression of advanced and complicated lesion, thus emphasizing the need for early intervention. The elevated serum cholesterol is the strongest risk factor for Coronary Artery Disease (CAD). Serum cholesterol levels correlate well with presence and severity of CAD in Indians. Population studies have shown that lowering blood cholesterol levels reduces the risk of heart attack. Further studies have shown that atherosclerosis may be prevented from getting worse—and sometimes even reversed, if cholesterol is lowered very well.
An aneurysm is a localized dilation, or bulging, in an artery. Aneurysms can occur anywhere, but they are most common and most troublesome when they are in a cerebral artery or in the aorta. Atherosclerosis and high blood pressure may both cause a portion of the muscular layer of the artery wall to degenerate, allowing the lining to balloon out at the point of weakness. Other causes of aneurysm are congenital weakness in the artery wall and, rarely, arterial inflammation.
An aneurysm can create problems if a blood clot develops inside it, if it bursts, causing internal bleeding, or if it presses on neighboring organs, nerves or blood vessels. An aneurysm of the aorta is likely to cause turbulence in the flow of blood, which can, in turn, result in the formation of a clot. A piece of this blood clot may break away and lodge in any organ, interrupting its blood supply and causing damage to that organ. If the aneurysm is near the origin of the aorta, it may distort the aortic valve, thus making it incompetent — which means it does not close properly. The best way to prevent an aneurysm is to guard against atherosclerosis and to keep your blood pressure under control. If, however, you develop a sensation of pressure or an inexplicable lump anywhere on the body, but especially on the abdomen, and particularly if it throbs, see your doctor as soon as possible as this could indicate an aneurysm. You will probably have a simple X-ray and an ultrasound scan. Then, if necessary, the doctor will arrange for a special X-ray called an arteriograph to be taken, to help identify the exact location and extent of the problem.
If an aneurysm has already occurred, it cannot be reversed but it can sometimes be prevented from getting any bigger by a reduction in blood pressure. It can also sometimes be surgically removed, and an artificial graft inserted.
