    Objectives Percutaneous coronary intervention (PCI)-related cardiac enzyme elevation is an independent risk factor for adverse clinical outcomes, but preprocedural predictors of this complication have not been established. This study evaluated the morphological characteristics of culprit lesions by frequency-domain optical coherence tomography (FD-OCT), and examined their predictive value for procedure-related myocardial injury in patients undergoing elective PCI. Methods Sixty-eight patients treated by FD-OCT-guided elective PCI were studied. On the basis of the presence or absence of postprocedural plasma cardiac troponin T (cTnT) elevation, patients were divided into elevation (cTnT-E, n =25) and nonelevation (cTnT-nonE, n =43) groups. FD-OCT examinations of ...
