%DS, percentage diameter stenosis; Ds, dissection; F, female; IFD, intraluminal filling defect; LAD, left anterior descending coronary artery; LCX, left circumflex coronary artery; M, male; MI, myocardial infarction; MLD, minimum lumen diameter; NA, not available; NQWMI, non-Q wave myocardial infarction; QCA, quantitative coronary angiography; QWMI, Q wave myocardial infarction; RCA, right coronary artery; STSE, ST segment elevation on ECG; TIMI, thrombolysis in myocardial infarction; UA, unstable angina; VF, ventricular fibrillation.
*Clinical symptoms at initial stenting; †clinical presentation of stent thrombosis; ‡only troponin increase; §angiographic underexpansion of the stent was accepted after the procedure to avoid losing a major diagonal branch.
