Comment on: The impact of bariatric surgery on the risk of coronary revascularization.

Abstract

We read with great interest the study from Noubani et al. [1], which provides retrospective data on the impact of bariatric surgery on coronary revascularization, extracted from the New York State Statewide Planning and Research Cooperative System (SPARCS) database. The authors identified more than 500,000 patients with obesity (BMI >30 kg/m2) and compared those who had undergone bariatric surgery with those who had not. Patients were matched in a 1:5 ratio according to a range of variables. The primary outcome was coronary revascularization (CR), defined by percutaneous coronary intervention, coronary artery bypass grafting, or both.
