Although intravascular ultrasound (IVUS) guidance has been useful in stenting for unprotected left main coronary artery stenosis, its impact on long-term mortality is still unclear.In the MAIN-COMPARE registry, patients with stenosis a hemodynamically stable condition underwent elective under of IVUS (756 patients) or conventional angiography (219 patients). Patients acute myocardial infarction were excluded. The 3-year outcomes between 2 groups primarily compared using propensity-score matching entire and separate populations according to stent type. In 201 matched pairs overall population, there was tendency lower risk morality (6.0% versus 13.6%, log-rank P=0.063; hazard ratio, 0.54; 95% CI, 0.28 1.03; Cox-model P=0.061). particular, 145 receiving drug-eluting stent, incidence as (4.7% 16.0%, P=0.048; 0.39; 0.15 1.02; Cox model P=0.055). contrast, use did not reduce 47 bare-metal (8.6% 10.8%, P=0.35; 0.59; 0.18 1.91; P=0.38). target vessel revascularization associated guidance.Elective guidance, especially placement may rate when guidance.
