Coronary Artery Disease

Brief summary

The aims of study are (1) to compare early and 1-year graft patency rates in patients who underwent coronary artery bypass grafting (CABG) based on conventional coronary angiography(CAG) versus cardiac computed tomography(CT)-derived fractional flow reserve(FFR), and (2) to demonstrate difference in clinical outcomes between the 2 groups.

Detailed description

The CABG-COREA trial is designed as a randomized, controlled trial to recruit 96 patients who undergo coronary artery bypass grafting. Patients were randomized by use of a randomization table. Coronary arteries are revascularized based on conventional coronary angiography (quantitative coronary angiography) or cardiac computed tomography-derived fractional flow reserve according to the randomization result. The primary end point is to evaluate early and 1-year postoperative graft patency. The secondary end points are overall survival, freedom from cardiac death and freedom from MACCE(major adverse cardiac or cerebrovascular events).
