Gender differences of in-hospital outcomes in patients undergoing percutaneous coronary intervention in the drug-eluting stent era

Abstract

Most studies on gender difference of the in-hospital outcome of percutaneous coronary intervention (PCI) were performed in the predrug-eluting stents (DES) era. This study was performed to investigate whether gender influences the in-hospital outcome of PCI in the DES era. A total of 44,967 PCI procedure between January and December of 2014 from the nationwide PCI registry database in Korea were analyzed. The study population was male predominant (70.2%). We examined the association of gender with unadjusted and adjusted in-hospital mortality and composite events of PCI, including mortality, nonfatal myocardial infarction, stent thrombosis, stroke, urgent repeat PCI and bleeding requiring transfusion. Most of the study patients (91.3%) received DES. The incidence rates of in-hospital mortality (2.95% vs 1.99%, P
