Clinical Trial Summary

This is an multicenter, randomized, controlled, parallel group study. ST-Segment Elevation Myocardial Infarction (STEMI) patients with high thrombus burden(HTB) will be allocated to one of the following: intrathrombus thrombolysis or manual aspiration thrombectomy during primary percutaneous coronary intervention(PPCI).

Description:

The hypothesis for ATTRACTIVE trial is that the intrathrombus thrombolysis with microcatheter or pierced balloon compared to manual aspiration thrombectomy will reduce the incidence of major adverse cardiovascular events(MACEs), including cardiovascular death, recurrent myocardial infarction, cardiogenic shock, or heart failure rehospitalization, stent thrombosis and target-vessel revascularization at 1 year in STEMI patients with HTB undergoing PPCI.
