The main aim of this study is The rising rates of obesity, along with its associated morbidities, represent an important global health threat. Atherosclerotic cardiovascular disease (ASCVD) is among the most common and hazardous obesity-related morbidity, and it is especially prevalent among those who suffer from type 2 diabetes (T2DM). Bariatric surgery (BS) is known to help with effective weight management and reduce the burden of cardiovascular risk factors, especially T2DM.

A nested propensity-matched cohort study was carried out using the Clinical Practice Research Datalink. The cohort included 1186 patients with no past history of ASCVD, 593 of whom underwent BS and 593 propensity-score matched controls, followed up for a mean of 42.7 months. The primary end point was the incidence of new ASCVD; defined as new coronary artery disease (CAD), cerebrovascular disease (CeVD), peripheral arterial disease (PAD), or miscellaneous atherosclerotic disease; secondary end points included primary end point components alone and all-cause mortality. Patients who underwent BS had significantly lower rates of new ASCVD (hazard ratio [HR] 0.53, confidence interval [CI] 0.30-0.95, P = 0.032.
