________________ HEART DISEASE: CAUSE & PREVENTION V. P. Singh Generally all heart attacks occur when a narrowed coronary artery is closed by a blood clot, cutting off blood to the area fed by the clogged artery. But no one knows the exact cause of heart disease. A heart attack is signaled by moderate to severe angina, which is not relieved by rest. Angina occurs when the heart, because of narrowed arteries or some other circulatory problem, does not get enough oxygen. Thus angina pain is the heart's way of warning. This pain starts from the centre of the chest and spreads to the shoulders and down the insides of the arms. So when some one susPain in the chest can have many causes. pects he has angina pain, he should lie down with his head and shoulders raised to relieve the heart of stress, enabling it to replenish itself. If the bain does go away after resting it is further evidence of angina. The human heart is a pump. Like most pumps, the heart needs to exert a certain amount of force to push the blood through circulatory system. But the main thing is that the heart has to work against the arterioles. The arterioles restrict the blood flow, forcing it through the capillaries, some of which are so small that blood cells can only move through them one cell at a time. Furthermore the human body is a complex factory, capable of synthesizing many diffect substances. One of those substances is cholesterol. Cholesterol is present in every cell of the body. The body regulates its own blood chalesterol level through an elaborate and complex system. Attempts to tamper with this system may reduce blood cholesterol but can also upset the body's natural balance, causing a series of problems much more hazardous than high cholesterol. There are actually two forms of cholesterol: HDL (high density lipoprotein) and LDL (low density lipoprotein). The level of LDL in the body is controlled by the liver, which makes both LDL and HDL. The body also gets LDL from the food it digests. HDL goes Jain Education International For Private & Personal Use Only www.jainelibrary.org
