The Claim

In adults aged 45 years or older with preexisting cardiovascular disease and a body mass index (BMI) of 27 kg/m² or higher who do not have diabetes, once-weekly subcutaneous semaglutide at a dose of 2.4 mg reduces the incidence of major adverse cardiovascular events—defined as cardiovascular death, nonfatal myocardial infarction, and nonfatal stroke—by 20% compared to placebo over a mean follow-up period of 39.8 months.

In plain English

A weekly injection of semaglutide (2.4 mg) helps lower the risk of serious heart problems like heart attack, stroke, or heart-related death by 20% in people over 45 who have heart disease and are overweight, but don’t have diabetes, compared to a fake treatment.
