Twelve vs 24 Months of Dual Antiplatelet Therapy in Patients With Coronary Revascularization for In-stent Restenosis

2015年3月27日 更新者:Yujie Zhou、Beijing Anzhen Hospital

Twelve Versus 24 Months of Dual Antiplatelet Therapy in Patients With Percutaneous Coronary Intervention for In-stent Restenosis

Patients undergoing the percutaneous coronary intervention (PCI) for in-stent restenosis (ISR) are enrolled. All patients will be randomized to receive either 12 months or 24 months of dual antiplatelet therapy with a P2Y12 receptor antagonist in addition to aspirin, all patients continue receiving aspirin indefinitely. 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.

研究概览

详细说明

The ISR-DAPT Study is a multicenter, randomized controlled trial that will enroll 1000 subjects treated with percutaneous coronary intervention (PCI) for in-stent restenosis. All patients will be randomized to receive either 12 months or 24 months of dual antiplatelet therapy with a P2Y12 receptor antagonist in addition to aspirin after index procedure. All patients continue receiving aspirin indefinitely. 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 at 24 months.

措施说明
大体时间
Safety end point assessed by incidence of GUSTO moderate or severe bleeding.
大体时间:24 months
Specifically, bleeding complications are classified as severe if they are intracerebral or if they result in substantial hemodynamic compromise requiring treatment. Moderate bleeding is defined by the need for transfusion.
