Obesity, Cardiovascular Disease, and the Promising Role of Semaglutide: Insights from the SELECT Trial

Abstract

Cardiovascular disease (CVD) is a leading global cause of death, with preventable risk factors like obesity contributing most to it. Obesity's association with CVD originate from factors like inflammation, insulin resistance, and altered lipid profiles. Obesity also raises the risk of atrial fibrillation (AF) and sudden cardiac death. Semaglutide, a GLP-1 receptor agonist, initially used for weight loss and diabetes, emerged as a breakthrough in CVD prevention. The SELECT trial assessed semaglutide's impact on major adverse cardiovascular events (MACE). In this double-blind, placebo-controlled trial, 17,604 adults with CVD and obesity were given a weekly 2.4 mg dose of semaglutide or placebo. The trial observed a significant 20% reduction in MACE risk for those receiving semaglutide, demonstrating its potential in obesity-associated CVD prevention. This shift marks a transformative approach to obesity management and CVD prevention. However, further research is needed to fully comprehend semaglutide's cardiovascular benefits and potential risks.
