Drug-eluting stents (DES) contribute to a significant reduction in in-stent restenosis (ISR) and repeat revascularization [Vasospasm or arterial remodeling is common in atherosclerotic coronary artery disease (CAD) cases [Therefore, we assumed that there will be difference in minimal lumen diameter after DES implantation between patients with and without use of intracoronary nitrate. Accordingly, this prospective double-blinded randomized study is designed to compare the efficacy and safety between DES implantation in nitrate-induced maximally dilated vessels and conventional DES implantation in patients with CAD.
