^∗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.

p value refers to BMS versus DES comparison, Mann-Whitney U 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.
