This study is to compare clinical outcomes between quantitative coronary angiography-guided anatomic complete revascularization and fractional flow reserve-guided physiologic complete revascularization in patients with significant coronary artery disease undergoing percutaneous coronary intervention with drug eluting stent
Men or women between the ages of 19and older
Typical chest pain or objective evidence of myocardial ischemia suitable for PCI Significant lesions with a diameter stenosis of 50-90% in major epicardial coronary arteries ≥ 2.25 mm in diameter by visual estimation.
The patient or guardian agrees to the study protocol and the schedule of clinical follow-up, and provides informed, written consent, as approved by the appropriate Institutional Review Board/Ethical Committee of the respective clinical site.
Coronary lesions resulting in the expected inability to perform FFR (ex, severe tortuosity or extreme angulation of the vessels)
Chronic total occlusion
Failed PCI of severe stenotic (diameter stenosis > 90%) or ACS culprit lesions
Previous PCI within 6 months before the index procedure
