Long-term kidney outcomes of semaglutide in obesity and cardiovascular disease in the SELECT trial

Randomized Controlled Trial
Human
2024 Jul

The study looked at kidney health but also confirmed that semaglutide reduced heart problems by 20% in people with obesity and heart disease who don’t have diabetes, which is exactly what the claim says.

Semaglutide reduces the absolute risk of major cardiovascular events by 1.5%

Randomized Controlled Trial
Human
2024 Jan 15

The study found semaglutide was linked to 20% fewer heart problems compared to placebo, but the actual benefit for most people is small—only 1.5% fewer events—and many stopped taking it due to side effects.

Gold Standard Evidence Needed

According to GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this specific claim, ordered from strongest to weakest evidence.

Similar Assertions

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.

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.

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.

For adults with heart disease and obesity who don’t have diabetes, taking a weekly semaglutide shot (2.4 mg) leads to more than twice as many people stopping treatment because of side effects compared to those taking a dummy shot.
