    Abstract:
    The clinical manifestations of heart failure (HF), myocardial systolic and diastolic functions and the indices of remodeling of the left ventricle (L V) were compared to define the most informative characteristics of the myocardial reserve (MR) in patients with prior myocardial infarction (MI). Examination of 220 patients with MI indicated that the low LV ejection fraction reliably determined only a high functional class (FC) of HF. Myocardial diastolic dysfunction (DD) was equally characteristic of any FCs of HF and the restrictive type of blood filling was most commonly associated with FC III-IV of HF. LV concentric hypertrophy, as well as DD, occurred in all FCs of HF. The detection rate of LV eccentric remodeling significantly increased from 5.1% in FC I to 98.7% in FC IV, which characterized this process as the most characteristic while grading the decrease in MR in patients with MI.
