[Myocardial contractility in the early postoperative period after aortocoronary bypass and cardiac aneurysm resection].

Polycardiography was used to examine myocardial contractile parameters: preejection and ejection periods and contractility coefficient in 90 patients with coronary heart disease running without complications postoperatively following aortocoronary bypass and cardiac aneurysm resection. The magnitude and length of lower myocardial contractility were found to be associated with the baseline extent of coronary and cardiosclerosis, the signs of congestive heart failure, the value of ejection fraction, and intraoperative parameters such as the duration of extracorporeal circulation and myocardial ischemia, the number of shunts and their blood flow. Early drug correction of complications and a scientifically substantiated approach to the physical rehabilitation of those operated on may be applied with due account of the changes in myocardial contractility.
