Diseases Of Heart
Ischemic heart disease is a generic for a set of closely related disorders where there is an imbalance between the supply of oxygen and heart demand substrates. Ischemia is due to an obstruction of the blood irrigation to the heart muscle and cause, as well as hypoxemia, a deficit of necessary substrates for the production of ATP and an abnormal accumulation of waste products from the cellular metabolism. The narrowing of the coronary arteries that supply the heart occurs primarily by the proliferation of smooth muscle and irreversible deposit lipids, especially esters and cholesterol crystals. The main lesion on the inside of the blood vessels of the heart is called atherosclerotic plaque, surrounded by a layer of fibrosis – puff heart: murmurs heart (or heart murmurs) are pathological noises that are perceived with the use of the stethoscope auscultation and are caused by increase of flow through a normal heart valve, by alterations of these valves (stenosis, insufficiency, double injury), by certain intracardiac anomalies (interventricular communication) or extracardiacas (arterial stenosis, patent ductus arteriosus, persistent, arteriovenous fistulae). -Heart failure: heart failure (CI) is the disability from diseases of the heart pump blood in more adequate volumes to meet the demands of mental metabolism if it succeeds, does so at the expense of a chronic decrease in the cardiac ventricles fill pressure – heart attack and unstable angina: occurs when blood flow to a part of the heart is blocked long enough so that part of the myocardial damage or die. Doctors call this myocardial infarction. -Diseases of the coronary arteries: coronary artery disease is a type of heart disease. The coronary arteries are blood vessels that carry blood and oxygen to the heart muscle – atrial fibrillation: the atrial fibrillation (AF) is the most frequent in practice cardiacP40 arrhythmia La FA clinica.1 is a disease in which the Atria or upper Chambers of the heart beat in a manner not coordinated and disorganized, which produces a rapid and irregular heart rate (i.e., irregular heartbeat)..
