• Status: Unknown status
• Trial end date: 2015-06-01
• Target enrollment: 0
• Participant gender: All

Summary

Patients undergoing the percutaneous coronary intervention (PCI) for in-stent restenosis (ISR) are enrolled.

The primary efficacy end points of this study are the incidence of a composite end point including all cause deaths, myocardial infarction, the incidence of Academic Research Consortium defined definite or probable stent thrombosis and stroke (MACCE) at 24 months. The primary safety end point is the incidence of GUSTO moderate or severe bleeding.
