Overview

Supports early IV streptokinase in AMI within 3 h; extends RCT evidence for thrombolysis on myocardial salvage.

Structured PICO

Does intravenous streptokinase reduce infarct size and improve left ventricular function in patients with acute myocardial infarction within 3 hours of symptom onset?

P
Population
64 patients with acute myocardial infarction within 3 hours after the onset of symptoms
I
Intervention
Streptokinase 1,500,000 IU via 1-hour intravenous infusion
C
Comparator
Conventional therapy
O
Outcome
Infarct size estimated in CK gram equivalent (CKg) by measurement of CK-MB every 3 hours during a 48-hour periodsurrogate

Early intravenous streptokinase infusion in acute myocardial infarction reduces infarct size and improves left ventricular function, with benefits closely correlated to vessel patency.
