Cardiosclerosis (synonym myocardiosclerosis) is a disease of the heart muscle due to development in her scar connective tissue (Fig. 2 and 3).cardiosclerosis

There are atherosclerotic cardiosclerosis and myocarditis. Atherosclerotic cardiosclerosis occurs on the soil of myocardial infarction (postinfarctne, focal cardiosclerosis) and chronic coronary insufficiency, associated with the defeat of vessels of the heart (diffuse cardiosclerosis). In all cases is the death of a part of the muscle fibers and their replacement by connective tissue.
Early clinical manifestation of atherosclerotic cardiosclerosis is reduced efficiency and a more rapid fatigability, both physical and mental. Then you receive shortness of breath, first only at considerable physical strain, and later with a normal physical work and walking. Marked expansion of cardiac dullness left, muting tone of the heart. Often cardiac arrhythmia (extrasystoles, atrial fibrillation).
If the development of scar tissue occurs in the course of conducting system, the patient develops heart block (see heart Arrhythmia). Often atherosclerotic cardiosclerosis is accompanied by the appearance of heart failure (see Circulation insufficiency)attacks, cardiac asthma, lung edema, and further increase of the liver, development and subcutaneous abdominal swelling.
For atherosclerotic cardiosclerosis long. Capacity for work is determined by the degree of heart failure.
Myocarditis cardiosclerosis is a consequence of myocarditis any nature. Unlike atherosclerotic cardiosclerosis, myocarditis cardiosclerosis has no tendency to progression, if the inflammatory process in the attack ended.
Treatment of atherosclerotic cardiosclerosis includes: therapy of atherosclerosis (see), coronary insufficiency (see angina), circulatory failure (see), arrhythmia (see). Treatment miotaticheskogo cardiosclerosis depends on its manifestations (circulatory failure, arrhythmia and other) and is conducted according to the same principles as in atherosclerotic cardiosclerosis.
