Impact of Sex on Clinical and Angiographic Outcomes Among Patients Undergoing Revascularization With Drug-Eluting Stents

Objectives The goal of this study was to investigate sex-based differences in long-term clinical and angiographic outcomes after coronary revascularization with drug-eluting stents (DES). Background The impact of sex on clinical and angiographic outcomes following revascularization with DES is not well established. Methods Individual patient data from 3 all-comers randomized DES trials (SIRTAX, LEADERS, RESOLUTE All-Comers) were pooled. Of 5,011 patients, 4,885 (97.5%) completed 2-year follow-up (1,164 women, 3,721 men). Protocol-mandated angiographic follow-up was available for 1,561 lesions (351 among women, 1,210 among men). The primary endpoint was the composite of cardiac death and myocardial infarction (MI) at 2 years. Results At baseline, women, as compared with men, were older, more frequently had diabetes, obesity, and hypertension, less frequently had smoking habits, previous MI, and previous surgical revascularization, and had a smaller reference diameter of the target vessel as well as a lower SYNTAX score. After adjustment for baseline differences, women and men had a similar risk of cardiac death or MI (odds ratio [OR]: 1.13, 95% confidence interval [CI]: 0.82 to 1.56, p = 0.44), cardiac death (OR: 1.0 Conclusions The unrestricted use of DES is associated with similar long-term safety and efficacy among women and men with coronary artery disease.
