This study looked at whether a drug called semaglutide helps prevent heart problems in people with heart disease but no diabetes. It found the drug slightly lowers the chance of some heart issues but causes stomach problems in many people.
Surprising Findings
The headline 20% relative risk reduction masked a very small absolute benefit of just 1.5%.
Patients and media often interpret relative risk reductions as life-changing, but here it means only 1.5% of people actually avoided an event—far less dramatic.
Practical Takeaways
Discuss both the small heart benefit and high side effect risk with your doctor before starting semaglutide for heart protection if you don’t have diabetes.

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%.
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.
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.
For people with heart disease, taking semaglutide means about 1 in 12 will stop treatment because of stomach problems like nausea or diarrhea — much more common than with a dummy pill.
