Among patients with type 2 diabetes and obesity, bariatric surgery is associated with a significant reduction in the rate of subsequent major cardiovascular events, researchers say.

The US study found the patients who had weight loss surgery were about 39% less likely to experience events including unstable angina, myocardial infarction, atrial fibrillation, heart failure, stroke, kidney disease or death from any cause over median follow-up of 3.9 years.
