Previous studies have shown a relation between female gender and adverse outcomes after percutaneous coronary intervention (PCI). The aim of this study was to determine whether there are differences in correlates between genders for these long-term adverse outcomes in patients with acute coronary syndromes. Gender differences were evaluated in the clinical outcomes of 6,929 consecutive patients with acute coronary syndromes from a large, contemporary PCI registry. Rates of major adverse cardiovascular events, defined as all-cause mortality, myocardial infarction, and target lesion revascularization at 1-year follow-up, are reported. Independent correlates of adverse outcomes were identified using multivariate proportional-hazards regression analysis. Women were older (p <0.001); had a higher prevalence of diabetes mellitus (p <0.001), systemic hypertension (p <0.001), chronic renal insufficiency (p = 0.02), peripheral arterial disease (p <0.001), and congestive heart failure (p <0.001); had lower body surface areas (p <0.001); and had higher body mass indexes (p <0.001). Acute coronary syndrome presentation in women tended to be unstable angina pectoris with Canadian Cardiovascular Society class III and IV symptoms, whereas men had more acute myocardial infarctions. At 1 year, the unadjusted rates of all-cause mortality (10.7% vs 7.5%, p <0.001) and major adverse cardiovascular events (16.4% vs 12.7%, p <0.001) were higher in women. There was a stark difference between the genders in independent correlates of mortality and major adverse cardiovascular events at 1 year. Moreover, the traditional correlates did not have the same impact in women as in men. In conclusion, although there are differences in clinical outcomes after PCI for women compared with men, there are different correlates for these adverse outcomes. These gender-based differences should be taken into account when women undergo contemporary PCI.
