INFORMATIVE POWER OF PARAMETERS OF LEFT-V ENTRICULAR SYSTOLIC FUNCTION OBTAINED IN ACUTE-PHASE OF MYOCARDIAL-INFARCTION FOR PROGNOSIS OF HEART-FAILURE IN POSTINFARCTION PERIOD

Central hemodynamics was studied by echocardiography and integral body rheography in 32 healthy persons and in 136 patients with proven tran smural myocardial infarction on days 1, 7, 21 - 28, and in 6 months af ter onset of infarction. Groups of patients with and without symptoms of heart failure in postinfarction period differed significantly by de gree of changes of parameters of left ventricular systolic function. T his difference existed beginning from bay 1 of infarction. The probabi lity of development of heart failure in postinfarction period could be estimated on days 1 - 7 of infarction by degree of lowering of stroke index and increase of end-diastolic and end-systolic left ventricular volumes. Increase of end-systolic left venrticular volume in acute ph ase of infarction was the earliest prognostic sign of development of h eart failure in postinfarction period.
