Optimal Coronary Flow After PCI for Myocardial Infarction - a Pilot Study

Summary

In this study the investigators test the hypothesis that alteplase given intra coronary after PCI reduce infarct size in patients with ST-elevation myocardial infarction(STEMI) and impaired microvascular function defined as a value of index of microvascular resistance (IMR) \>30.
