Influence of enhanced external counterpulsation on hemodynamics and clinical course in acute myocardial infarction

Research aim was to estimate influence of EECP on hemodynamics in patients with acute Q-myocardial infarction and its clinical course. Open, monitored, not randomized research using a method of groups of parallel comparison is conducted. 48 patients with acute Q-myocardial infarction were included in the research, 22 in the basic group and 26 in the control group. Patients of the basic group received sessions of EECP for 30 minutes during 7 days. EECP didn't lead to statistically significant augmentation of average value of key parameters of a hemodynamics immediately after the session. The maximum decline in the pumping and contractile function of left ventricle in patients with acute Q-infarction was observed on the third day, followed by their increase and stabilization on the 7-21-st day of the disease. Slight increase of the pump performance and contractility of the left ventricle by the 7th day of the research without negative dynamics on the third day of the disease was observed against EECP. Changes between the groups were leveled by the end of the study. In control group cases of delirium and pneumonia were credibly more often. EECP is safe enough for using in acute and subacute period of Q-myocardial infarction. Group with EECP was characterized by better indicators of systolic function in acute period of Q-myocardial infarction and also by more favorable clinical course.
