The research analyzed cases of death, reinfarction and heart failure in patients that survived myocardial infarction (MI), after coronary artery bypass grafting (CABG) and studied influence of surgery on intracardiac
hemodynamics. Restoration to level of I–II functional class from initial III–IV functional class in 80 % patients and significant increase of left ventricular ejection fraction were registered. Functional restoration after CABG was insufficient in patients with heart failure II А stage before surgery. We established predictors of restoration to I–II functional class: non-Q MI, one- or two-vessel disease, re-MI, absence of heart failure II А stage before operation) and of insufficient restoration and conservation of heart failure II А stage (Q-MI, more than two MI, presence of heart failure II А stage before operation, presence of left ventricular aneurysm, dyskinesis, dilatation, restrictive type of diastolic dysfunction, ejection fraction lower than 40 %, increase of the left ventricular mass index more than 125 g/m2).
