The heart is the organ that pumps blood, with its life-giving oxygen and nutrients, to all tissues of the body. If the pumping action of the heart becomes inefficient, vital organs like the brain and kidneys suffer.And if the heart stops working altogether, death occurs within minutes. Life itself is completely dependent on the efficient operation of the heart.
There are many kinds of heart disease, and they can affect the heart in several ways. But the ultimate problem with all varieties of heart disease is that, in one way or another, they can disrupt the vital pumping action of the heart
PREVETING HEART DISEASE
The best way to "treat" heart disease is to avoid it altogether. Taking steps to adopt a healthy lifestyle can significantly reduce your risk of heart disease, and increase your odds of living a long and healthy life. Here's what you need to know.
What is coronary artery disease?
Coronary artery disease (CAD) is arteriosclerosis of the inner lining of the blood vessels that supply blood to the heart. CAD is a common form of heart disease and is a major cause of illness and death. CAD begins when hard cholesterol substances (plaques) are deposited within a coronary artery. (The coronary arteries arise from the aorta, which is adjacent to the heart.) The plaques can cause a tiny clot to form which can obstruct the flow of blood to the heart muscle. Symptoms of CAD include 1) chest pain (angina pectoris) from inadequate blood flow to the heart; 2) heart attack (acute myocardial infarction), from the sudden total blockage of a coronary artery; or 3) sudden death, due to a fatal rhythm disturbance.
