Data are presented as means ± SD or n (%) or n/total n (%).
OCT, optical coherence tomography; STEMI, ST-elevation myocardial infarction.
aPatients may have more than one qualifying characteristic.
bData are shown for STEMIs that had occurred more than 24 h after symptom onset.
cThe stent length reflects the continuous length or the total length of separated stents in any single-target vessel.
dTwo-stent bifurcation was treatment with a stent at least 2.5 mm in diameter in both the main vessel and side-branch vessel.
eSevere calcification was defined as visible calcification on both sides of the vessel wall in the absence of cardiac motion.
fA chronic total occlusion could be a qualifying characteristic only after the occlusion had been successfully crossed with antegrade wire escalation and pre-dilatation.
gAdvanced lesion preparation includes treatment with a cutting or scoring balloon, atherectomy, lithotripsy, or laser before implantation of the stent.
