Obesity is one of the most significant reasons to induce cardiac-cerebrovascular adverse events. Bariatric and metabolic surgery is increasingly recognized as a safe and effective intervention to achieve marked weight loss, and improvement in obesity-related complications, including type2 diabetes mellitus, hypertension and metabolic syndrome. There is observational evidence that bariatric and metabolic surgery in obese patients could decrease risk factors, including inflammation, hypertension, dyslipidaemia, however, further studies are still needed to indentify the correlation of bariatric and metabolic surgery and reduced rates of cardiac-cerebrovascular adverse events. This article summarizes the effects of bariatric and metabolic surgery on cardiac-cerebrovascular adverse events in obese patients in order to illustrate its clinical significance and application value.
