MYOCARDIAL FUNCTION DYNAMICS IN PATIENTS WITH ACUTE CORONARY SYNDROME

Abstract

The myocardial function has been studied in 30 patients in the acute phase of acute coronary syndrome, ACS (19 and 11 individuals with and without ST segment elevation, respectively). Electrocardiography and tetrapolar integral rheography were performed at Days 1-2, 5-6, and 15-20. It was demonstrated that ACS with ST elevation was associated with reduced myocardial functional reserve and activation of adaptive mechanisms supporting adequate blood flow. ACS without ST elevation, due to the less severe myocardial injury, was characterised by the activation of cardiac compensatory mechanisms preventing heart failure progression. Extracardiac compensatory mechanisms were involved to a lesser extent.
