Semaglutide administration significantly reduces the incidence of atrial fibrillation by 42% compared to placebo in patients at high cardiovascular risk, primarily those with type 2 diabetes or obesity.

If you have type 2 diabetes or are overweight with high heart disease risk, ask your doctor about semaglutide. This medication has been shown to significantly lower your chance of developing atrial fibrillation, a common heart rhythm problem, regardless of whether you take it as a pill or a weekly injection. This benefit exists even if you do not have diabetes.

GoodSupportsHIGH confidence
Semaglutide reduces the risk of AF by 42% (RR .58, 95% CI .40–.85)... Semaglutide significantly reduces the occurrence of incident AF by 42% as compared to placebo in individuals at high CV risk, mainly affected by type 2 diabetes mellitus.

Why this rating

Based on a systematic review and meta-analysis of 10 RCTs with low heterogeneity (I2 0%), though AF was a secondary safety outcome in the original trials.
