• This study sought to assess sex differences in chest pain after percutaneous coronary intervention (PCI) with newer generation drug-eluting stents (DES). Sex-based data on chest pain after PCI with DES are scarce. The authors performed a patient-level pooled analysis of the TWENTE and DUTCH PEERS randomized trials, in which patients were treated with newer generation permanent polymer-coated DES. At 1 and 2 years, clinical follow-up was available in 99.8% and patient-reported chest pain data in 94.1% and 93.6%, respectively. Among all 3,202 patients, the 871 (27.2%) women were older (67.5 ± 10.2 years vs. 62.8 ± 10.6 years; p < 0.001) and had more cardiovascular risk factors: diabetes (24.2% vs. 17.8%; p < 0.001), hypertension (63.6% vs. 51.6%; p < 0.001), and positive family history (54.5% vs. 50.1%; p = 0.03). At 1- and 2-year follow-up, women reported more clinically relevant chest pain (16.3% vs. 10.5%; p < 0.001, and 17.2% vs. 11.1%; p < 0.001, respectively). Multivariate analysis demonstrated that female sex independently predicted clinically relevant chest pain at 1- and 2-year follow-up both during daily activities and at minimum physical exertion/at rest (1 year adjusted odds ratio [OR]: 1.7; 95% confidence interval [CI]: 1.2 to 2.4; p = 0.002; and adjusted OR: 1.8; 95% CI: 1.3 to 2.5; p < 0.001; 2-year adjusted OR: 1.8; 95% CI: 1.3 to 2.6; p < 0.001; and adjusted OR: 1.7; 95% CI: 1.3 to 2.3; p = 0.001). Nevertheless, the 2-year rates of death, myocardial infarction, revascularization, stent thrombosis, and various composite clinical endpoints were similar for both sexes. Although the incidence of adverse cardiovascular events was low and similar for both sexes, women showed a statistically significantly higher prevalence of clinically relevant chest pain, which might be largely related to mechanisms other than epicardial coronary obstruction.
