For people with heart disease but not diabetes, taking semaglutide seems to lower the chance of having a non-fatal heart attack over about three years — 2.7% of users had one versus 3.7% who didn’t take it.

If you're 45 or older, have heart disease, and are overweight but don’t have diabetes, taking semaglutide for about 3 years might lower your chance of having a serious heart problem by a small amount — about 1.5%. That means 67 people need to take it for one person to avoid a heart event, which gives a clearer picture than the often-shared 20% drop in risk.

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.

If you're obese and have heart disease but not diabetes, taking semaglutide might lower your chances of having a serious heart problem by 20%.

Taking a weekly semaglutide shot (2.4 mg) for about a year and a half can help lower blood pressure, blood sugar, bad cholesterol, and body-wide inflammation in adults with extra weight but no diabetes—better than a placebo.

Even if you don’t have diabetes, if you’re overweight and have heart disease, a weekly shot of semaglutide can cut your risk of heart attack or stroke by 1 in 5 — and this benefit starts before you lose much weight.
