Semaglutide significantly reduces the risk of atrial fibrillation (AF) and sinus node dysfunction in patients with overweight or obesity.

If you have overweight or obesity and are concerned about heart rhythm issues like atrial fibrillation, semaglutide therapy (up to 2.4 mg) has been shown in large studies to significantly lower that risk. This benefit appears particularly strong in patients over 60 and those treated for more than a year.

GoodSupportsHIGH confidence
Compared with the controls, semaglutide significantly reduced the risk of atrial fibrillation (AF) (RR 0.79, 95% CI 0.63–0.99), sinus node dysfunction (RR 0.43, 95% CI 0.19–1.00)...
