Mahajan AM, et al. - Among patients who underwent percutaneous coronary intervention (PCI) between 2010-2016, researchers assessed the differences in 1-year outcomes by sex in four ethnic groups, focusing on 1-year major adverse cardiovascular events (MACE, a composite of all-cause death, non-fatal myocardial infarction, or target lesion revascularization). Overall 16,361 patients, including 7,881 whites (26.1% women), 1,943 blacks (47.3% women), 2,621 Asians (22.6% women), and 3,916 Hispanics (39.3% women) were included in this prospective cohort study. In whites, Asians, and Hispanics, women vs men demonstrated a similar risk of 1-year MACE, after adjustment. In blacks, a lower risk of 1-year MACE was found in women vs men, mostly due to a lower risk of death or MI. Overall, women experienced adverse events after PCI in the presence of risk factors.
