Previous studies have demonstrated that use of intravascular ultrasound (IVUS) during percutaneous coronary intervention (PCI) was associated with lower incidence of death, myocardial infarction, and target vessel revascularization. Recently, optical coherence tomography (OCT) has emerged as an alternative intravascular imaging device with better resolution. The aim of this study was to investigate frequency and prognostic impact of IVUS or OCT-guided PCI during urgent revascularization for acute myocardial infarction diagnosed by the universal definition. A total of 2788 patients who underwent urgent PCI were selected from a multicenter, Japanese registry of acute myocardial infarction diagnosed by universal definition (J-MINUET). Frequency, clinical characteristics and prognostic impact of the IVUS-, or OCT- guided PCI were investigated. Clinical endpoint was in-hospital death. Angiography-, IVUS-, and OCT-guided urgent PCI were performed in 689 (24.7%), 1947 (69.8%), and 152 (5.5%) patients. In-hospital death in each group was 10.4%, 5.1%, and 3.3%, respectively (P < 0.01). By univariate and multivariate logistic regression analysis, IVUS-guided PCI (vs. angiography-guided PCI, OR 0.49, 95% CI 0.30–0.81, P = 0.006) was a significant independent predictor of in-hospital death. Intravascular imaging guided-PCI was frequently adopted during urgent PCI for acute myocardial infarction diagnosed by universal definition and was associated with better in-hospital survival.
