[State of general and renal hemodynamics in acute myocardial infarct].

The results of studying central and renal hemodynamics in 49 patients with a different course of myocardial infarction in the acute period (1st, 3rd, and 10th day) are analysed. It was established that on the 1st day the cardiac output decreases considerably in circulatory insufficiency and hardly changes in an uncomplicated course of the disease. The stroke output of the heart reduces significantly in all forms of the course of myocardial infarction. At an increase of total peripheral resistance is observed in myocardial infarction, particularly in circulatory insufficiency. A significant increase in the central hemodynamics indices is noted at the end of the acute period. On analysing the dependence of central and renal hemodynamics, the authors conclude that local mechanisms are involved in the changes in renal hemodynamics in addition to its dependence on the disorders of central hemodynamics.
