Data missing in 10 cases (1 BMS, 9 DES). †Data missing in 2 cases (2 DES). Data expressed as median (range) or count (%) for continuous or discrete variables, respectively. value refers to BMS versus DES comparison, Mann-Whitney test, or Fisher’s exact test for continuous or discrete variables, respectively. PCI = percutaneous coronary intervention. STEMI = ST-segment elevation myocardial infarction. IVUS = intravascular ultrasound.
