Time‐Dependent Impact of Sex on the Long‐Term Outcomes After Left Main Revascularization

BACKGROUND: There are still limited data about the differential effect of sex on long‐term outcomes after percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) for left main coronary artery disease. This extended follow‐up study of the MAIN‐COMPARE (Ten‐Year Outcomes of...

Sumario:BACKGROUND: There are still limited data about the differential effect of sex on long‐term outcomes after percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) for left main coronary artery disease. This extended follow‐up study of the MAIN‐COMPARE (Ten‐Year Outcomes of Stents Versus Coronary‐Artery Bypass Grafting for Left Main Coronary Artery Disease) registry evaluated clinical outcomes beyond 10 years. METHODS AND RESULTS: Of 2240 patients with unprotected left main coronary artery disease (PCI=1102 and CABG=1138), all‐cause mortality, the composite of death, Q‐wave myocardial infarction, or stroke, and target vessel revascularization were separately evaluated in both sexes. Of 2240 patients, 631 (28.2%) were women and 1609 (71.8%) were men. Women had lower 10‐year incidences of death and serious composite outcomes than men. The adjusted 10‐year risks of adverse outcomes were similar in men. However, the adjusted 10‐year risks were different according to a prespecified period in women. In the short‐term (0–1 year) period, PCI had a significantly lower risk for serious composite outcomes (adjusted hazard ratio [HR], 0.41; 95% CI, 0.19–0.91; P=0.03) compared with CABG. The adjusted risks for death and serious composite outcomes were significantly higher after PCI than after CABG, during the midterm (1–5 years) period (death; adjusted HR, 3.99; 95% CI, 2.01–7.92; P<0.001 and composite outcome; adjusted HR, 2.93; 95% CI, 1.59–5.39; P=0.001). Beyond 5 years, adjusted risks were similar after PCI and CABG in women. CONCLUSIONS: In this 10‐year extended follow‐up study of patients undergoing left main coronary artery revascularization, we observed a time‐dependent impact of sex on the long‐term outcomes after PCI and CABG, especially in women, with significant interactions. However, these results warrant confirmation on larger series of studies. REGISTRATION: URl: https://www.clinicaltrials.gov; Unique identifier: NCT02791412.
