[Systemic thrombolytic therapy in acute myocardial infarct: its effect on left ventricular function, body oxygen consumption and disease prognosis].

Echocardiography, integral rheography of the body, Holter monitoring, assessment of oxygen consumption and blood gases were used in examination of 93 patients with macrofocal myocardial infarction (MI). 48 patients received thrombolytic therapy (TT) within 6 hours of MI which in 27 patients implied standard drugs (streptodecase, celiase, avelysin) and new medicine APSAC (21 patients). 45 patients received no TT. It was found that in acute MI period systemic TT prevented a fall in left ventricular performance, promoted advanced oxygen supply due to intensified oxygen extraction by tissues. This fact is attributed to transient changes in blood rheology. Application of APSAC prevented inhibition of myocardial contractility and development of congestive heart failure in subacute MI period. TT patients demonstrated ventricular arrhythmia on MI day 1 more often though by the number of the main arrhythmia types the groups differed insignificantly. Within 1-year postmyocardial infarction period TT patients had less repeat MI and were less frequently diagnosed to develop congestive heart failure.
