SELECT Trial: Semaglutide and Cardiovascular Risk, Explained

What the SELECT trial showed about semaglutide and heart outcomes in people with obesity but without diabetes, in plain language.

Direct Answer

Does semaglutide reduce heart-attack and stroke risk?

In the SELECT trial (New England Journal of Medicine, 2023), semaglutide 2.4 mg reduced the risk of major adverse cardiovascular events — cardiovascular death, heart attack, or stroke — by about 20% in adults with established cardiovascular disease and obesity but without diabetes. This was a landmark finding beyond weight loss alone.

Compounded medications are not FDA-approved finished drug products and should only be prescribed when clinically appropriate by a licensed healthcare provider. Brand-name medications such as Ozempic, Wegovy, Mounjaro, and Zepbound are FDA-approved under their own applications. Compounded semaglutide and compounded tirzepatide are not FDA-approved finished drug products.

What SELECT measured

SELECT enrolled adults with prior cardiovascular disease and overweight/obesity, without diabetes, and followed cardiovascular outcomes over several years. The roughly 20% relative risk reduction supported a cardiovascular benefit independent of glucose lowering.

What it means and doesn't mean

SELECT studied FDA-approved semaglutide under medical supervision. It does not establish the same outcomes for compounded products, which are not FDA-approved. Any cardiovascular use should be guided by a clinician.
