Cardiosclerosis - a lesion muscles (myocardiosclerosis) and valves of heart owing to development in them a cicatrical tissue in the form of sites of various size (from microscopical up to the large cicatrical centers and fields) and the prevalence, replacing a myocardium or deforming valves. Is an outcome of rheumatic disease and myocardites of the different nature or an atherosclerosis of coronary arteries. Clinical value of a cardiosclerosis of other parentage (an outcome of a dystrophia and a hypertrophy of a myocardium, a trauma of heart, its other illnesses) is insignificant.

The diagnosis. As displays of a myocardiosclerosis stable arrhythmias and disturbances of endocardiac conduction, a chronic heart failure serve. The atherosclerotic cardiosclerosis can cause valval defects almost exclusively in the form of a failure of mitral or aortal valves; at an atherosclerotic cardiosclerosis there can be attacks of a stenocardia, and also can develop chronic an aneurysm of heart. Current more often slowly progressing owing to chronically recurring (rheumatic disease) or character of the basic illness progressing (atherosclerosis). Treatment of the basic illness; pathogenetic therapy of separate syndromes; arrhythmias, atrioventricular blockade, a chronic heart failure (considering, that at a cardiosclerosis tolerance of a myocardium to intimate glycosides, as a rule, decreases).
