Effect of Adjunctive Intracoronary Streptokinase on Late Term Left Ventricular Infarct Size and Volumes in Patients With Acute Myocardial Infarction

June 22, 2009 updated by: Istanbul University

Phase 4 Study of Application of Intracoronary Low Dose Streptokinase Complementary to Standard Percutaneous Coronary Intervention in Patients With ST Elevation Acute Myocardial Infarction: Effect of Adjunctive Intracoronary Streptokinase on Late Term Left Ventricular Infarct Size and Volumes in Patients With Acute Myocardial Infarction

The investigators hypothesized that complementary intracoronary streptokinase administration to primary percutaneous intervention in patients with acute myocardial infarction may provide limitation infarct size and improvement in left ventricular volumes and function in acute and late phases (6 months).
