[State of microcirculation in various zones of the heart in myocardial infarct complicated by congestive circulatory insufficiency].

A definite correlative connection has been revealed between the clinical course of myocardial infarction, the extent of affection of the heart muscle, the severity of the atherosclerotic process in the coronary arteries, and the condition of microcirculation in different zones of the heart. The severest affections of the heart muscle, stenosing coronarosclerosis and disorders of microcirculation in different zones of the heart were encountered in patients with myocardial infarction marked by a recurrent course and complicated by cardiogenic shock or congestive circulatory insufficiency. It is shown that the character of changes in microcirculation determines to a great measure the later condition of the structure and function of the myocardial muscle cell in areas near and remote from the infarction.
