coronary ischemic heart disease

Cardiovascular disease is also known as atherosclerotic heart disease, coronary heart disease, and ischemic heart disease. It comes as the result of atheromatous plaques clogging the arteries of the heart muscle, which is known as the myocardium. Symptoms of cardiovascular disease often does not manifest itself until several decades after the fact, often the result of a serious heart attack. After years of accumulation of the plaques can rupture, and thus the amount of blood that the heart muscle, the heart attack . coronary heart disease is the commonest cause of sudden death. For men and women of advanced age, it is the most common cause of death.

When it comes to heart disease, atherosclerotic heart disease includes a broad spectrum. At one end you have asymptomatic people whose disease is characterized by atheromatous streaks within the walls of the coronary arteries. The strips do not impede blood flow, but rather the earliest stage of atherosclerotic heart disease. During this phase of the disease, a coronary angiogram may be no evidence that they exist. This is due to the fact that the coronary lumen's has not decreased in caliber.

As the years pass, the strip is always thicker and thicker. Initially, the expansion of atheromatous plaques in the artery walls, and then expand it into the lumen of the vessel. This affects the blood flow in the arteries. Originally it was assumed that atheromatous plaques grow over a lengthy process. But in recent years, it was learned that the development of plaque could be supplemented by small fractures, leading to a sudden increase in the plaque by the accumulation of thrombus material.

If less than seventy percent of the vessel diameter is obstructed, symptoms of obstructive coronary artery disease is rarely displayed. It is when more than seventy percent of the vessel diameter is obstructed by atheromatous plaques that the person begins to develop symptoms. This phase is known as ischemic heart disease. These characters begin to believe in times when the heart is an increased workload. Exertional angina pectoris and reduced load capacity are among the heads of the symptoms.

Since the disease carries, it may lead to an almost total obstruction of the coronary lumen's. Thus, the flow of blood with oxygen to the myocardium. Normally, when concerned with this phase of the disease, the victims of people from one or more heart attacks. They are also signs of a chronic coronary ischemia. These include symptoms of flash pulmonary edema and angina pectoris at rest.

It should be clear that there is a difference between myocardial infarction and myocardial ischemia. The term "ischemia" refers to the disruption in the amount of oxygen, becomes a fabric is that it is not sufficient for the needs of the tissue. If the heart muscle is affected by ischemia, is not able, to function properly. If it involves large parts of the heart muscle, the organ of relaxation and contraction may be impaired. "Infarction" means that the tissue has died, because a lack of oxygen-rich blood.
