A new analysis of a major clinical trial affirmed that Wegovy, the popular obesity drug, lowers the risk of major heart issues like heart attacks and strokes in some adults, but showed that weight loss could not fully explain the cardiovascular benefits. How else, exactly, the drug protects the heart remains a mystery. Obesity is intricately linked with poor heart health, and losing excess weight can blunt the risk of cardiovascular concerns. But the analysis, published on Wednesday in The Lancet, found that a shrinking waist size — a measure of shedding belly fat — was responsible for only around a third of the observed cardiovascular benefits in people who took Wegovy. In their first 20 weeks of taking the drug, patients experienced cardiovascular benefits no matter how much weight they lost. “As it stands now, we do not know how to account for that other roughly two thirds of the benefit,” said Dr. Michael Lincoff, a professor emeritus of medicine in the department of cardiovascular medicine at the Cleveland Clinic and an author of the paper.
