  Purpose

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).

Primary Outcome Measures:
  • Left ventricular infarct size by SPECT [ Time Frame: at long term (5-6 months) ] [ Designated as safety issue: No ]
  • Left ventricular diastolic volume [ Time Frame: at long term (5-6 months) ] [ Designated as safety issue: No ]
  • Left ventricular systolic volume [ Time Frame: at long term (5-6 months) ] [ Designated as safety issue: No ]
  • Left ventricular ejection fraction [ Time Frame: at long term (5-6 months) ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Temporal changes (from baseline to 5 months follow-up) in microvascular perfusion indices (index of microvascular resistance, coronary flow reserve) and in infarct size have been interrogated in only control group. [ Time Frame: early phase (at discharge) and late phase (5-6 months) ] [ Designated as safety issue: No ]
  • Reinfarction [ Time Frame: from recruitment until the last follow-up at 5-6 months ] [ Designated as safety issue: Yes ]
  • Major bleeding [ Time Frame: from recruitment to discharge ] [ Designated as safety issue: Yes ]
