*Type B2/C, the morphology of the lesion in coronary angiography was classified according to the criteria of The American College of Cardiology/American Heart Association.
LAD, left anterior descending artery; LCX, left circumflex artery; NSTE-ACS, non-ST elevation acute coronary syndromes; PCI, percutaneous coronary intervention; RCA, right coronary artery; SA, stable angina.
