Impact of Immediate Stent Implantation Versus Deferred Stent Implantation on Infarct Size and Microvascular Perfusion in Patients With ST-segment Elevation Myocardial Infarction (INNOVATION)

NCT02324348 NA COMPLETED

It is known that no reflow phenomenon by microvascular obstruction after revascularization in STEMI increase infarct size, cardiac remodeling, and a risk of late mortality. Major mechanism of microvascular obstruction is distal embolization during procedure. Some investigators showed deferred stenting decreased the degree of microvascular obstruction compared with immediate stenting in STEMI. The aim of current study is to compare impact of immediate stent implantation versus deferred stent implantation on infarct size and microvascular perfusion in patients with ST-segment elevation myocardial infarction (STEMI).
