BACKGROUND: Gender-based differences in diabetic patients are understudied in the field of percutaneous coronary intervention (PCI) with drug-eluting stents. METHODS: Data were obtained from a multicenter registry of 2420 consecutive patients with diabetes mellitus (DM) who underwent PCI with paclitaxel- or sirolimus-eluting stents between 2003 and 2009. Among them, 679 (28.1%) women were compared to 1741 (71.9%) men in terms of clinical aspects and major adverse cardiac events (MACE), including all-cause death, myocardial infarction (MI) and target lesion revascularization (TLR). Target vessel revascularization (TVR) and any revascularization were also reported. RESULTS: Women were less numerous, older, used more insulin and showed more tortuous coronary arteries, while men were more frequently smokers and received larger stents. At the median follow-up of 24.3months (interquartile range 12.3-39.7), MACE, TVR and any revascularization did not significantly differ between females and males (19.9% vs 18.7%, 12.2% vs 13.4%, 14.1% vs 15.1%, respectively). At multivariable analysis of the overall cohort, female gender was not a predictor of MACE (hazard ratio [HR] 1.02, 95% confidence interval [CI] 0.92-2.36, p=0.11), death (HR 1.04, 95% CI 0.84-1.24, p=0.86), MI (HR 1.48, 95% CI 0.92-2.36, p=0.11), and TLR (HR 1.14, 95% CI 0.85-1.52, p=0.38). CONCLUSION: In this registry of diabetic patients treated by drug-eluting stents, women were less represented, older and needed more insulin compared to men who, on the other hand, received larger stents. Gender-related outcomes were similar and female sex did not predict MACE.

BACKGROUND: Gender-based differences in diabetic patients are understudied in the field of percutaneous coronary intervention (PCI) with drug-eluting stents. METHODS: Data were obtained from a multicenter registry of 2420 consecutive patients with diabetes mellitus (DM) who underwent PCI with paclitaxel- or sirolimus-eluting stents between 2003 and 2009. Among them, 679 (28.1%) women were compared to 1741 (71.9%) men in terms of clinical aspects and major adverse cardiac events (MACE), including all-cause death, myocardial infarction (MI) and target lesion revascularization (TLR). Target vessel revascularization (TVR) and any revascularization were also reported.
