Diabetes mellitus has a greater effect on mortality rates due to coronary artery disease in women than in men. Although women undergoing coronary intervention in general have a higher frequency of adverse outcomes than men, the effect of gender among diabetic patients on clinical outcomes after percutaneous coronary intervention (PCI) has not been well established in the drug-eluting stent (DES) era. We have investigated the impact of gender on long-term clinical outcome in these high risk populations. We enrolled 404 consecutive patients (74 women and 330 men) with diabetes mellitus who underwent elective PCI (85% with DES). We evaluated the incidence of major adverse cardiac events (MACE), which is a composite of total all-cause death, acute coronary syndrome (ACS), and target lesion revascularization (TLR) during a period of 4 years after coronary intervention. The women were significantly older, more likely to have dyslipidemia, and had significantly higher systolic blood pressure and LDL-C values than men. The use of insulin and angiotensin receptor blockers was more frequent among the women (32.4% versus 21.0%, P = 0.04 and 60.8% versus 39.8%, P < 0.01, respectively). The angiographic profiles of both were comparable. At four-year clinical follow-up, cumulative incidence of MACE was identical between the women and the men (16.2% versus 15.5%, P = 0.90; adjusted HR 1.23, 95% CI 0.61-2.50, P = 0.56). Although the baseline characteristics of the women were worse, clinical outcomes did not significantly differ between women and men among diabetic patients after elective PCI.
