Heart Attack

A blockage in the heart's arteries may reduce or completely cut off the blood supply to a portion of the heart. This can cause a blood clot to form and totally stop blood flow in a coronary artery, resulting in a heart attack. In fact, all of the behaviors that you probably associate with heart disease or heart attack such as having high blood pressure, smoking, being overweight, eating foods high in fat and cholesterol, not exercising and having diabetes can also cause heart failure.

Main Causes

Atherosclerosis: Atherosclerosis is a gradual process in which plaques (collections) of cholesterol are deposited in the walls of arteries. Cholesterol plaques cause hardening of the arterial walls and narrowing of the inner channel of the artery. Arteries that are narrowed by atherosclerosis cannot deliver enough blood to maintain normal function of the parts of the body they supply. For example, atherosclerosis of the arteries in the legs causes reduced blood flow to the legs. Reduced blood flow to the legs can lead to pain in the legs while walking or exercising, leg ulcers, or a delay in the healing of wounds to the legs. Smoking, high blood pressure, high cholesterol, and diabetes mellitus can accelerate atherosclerosis and lead to the earlier onset of symptoms and complications.

Angina pectoris: Angina pectoris(Angina) is chest pain or pressure that occurs when the blood and oxygen supply to the heart muscle cannot keep up with the needs of the muscle. When coronary arteries are narrowed by more than 50 to 70 percent, the arteries cannot increase the supply of blood to the heart muscle during exercise or other periods of high demand for oxygen. An insufficient supply of oxygen to the heart muscle causes angina. Exertional angina usually feels like a pressure, heaviness, squeezing, or aching across the chest.

High blood pressure (hypertension): Uncontrolled high blood pressure increases a person's risk of developing heart failure by two to three times. When pressure in the blood vessels is too high, the heart has to pump harder than normal to keep the blood circulating. This takes a toll on the heart, and over time the chambers get larger and weaker.
