Previous studies have reported that women have worse outcomes than men after percutaneous coronary intervention (PCI), especially in patients with ST-elevation myocardial infarction. However, gender-related differences in patients with non–ST-elevation acute coronary syndromes (NSTE-ACS) have not been thoroughly investigated. In the Japanese nationwide registry, a total of 43,239 patients with NSTE-ACS from 861 hospitals underwent PCI in 2014. Overall, 11,326 patients (26.2%) were women. The women were older (75.0 ± 10.3 vs 68.7 ± 11.4 years, p <0.001) and had a higher prevalence of hypertension (p <0.001), hyperlipidemia (p = 0.003), and heart failure (p <0.001) compared with men. For inpatient outcomes, women had a higher rate of overall complications (3.3% vs 2.4%, p <0.001) and bleeding complications that required blood transfusion (0.6% vs 0.2%, p <0.001). On multivariate analysis, female gender was an independent predictor of overall (odds ratio [OR] 1.20, 95% CI 1.04 to 1.38; p = 0.011) and bleeding complications (OR 1.94, 95% CI 1.35 to 2.79; p <0.001) after adjustment but was not associated with in-hospital mortality (OR 1.05, 95% CI 0.79 to 1.40; p = 0.747). In conclusion, in patients with NSTE-ACS who underwent PCI, women were at greater risk than men for in-hospital complications, especially in bleeding complications.
