Oral semaglutide is associated with a significantly lower risk of incident atrial fibrillation (AF), while dulaglutide shows an increasing trend toward higher AF risk compared to controls.

Among GLP-1 medications, oral semaglutide (Rybelsus) may actually lower the risk of atrial fibrillation, while dulaglutide (Trulicity) might slightly increase it. This difference is drug-specific and not seen with all GLP-1s. If you have a history of AF, discuss the specific drug choice with your doctor.

In further subgroup analyses, we observed an increasing trend toward incident AF with dulaglutide (RR 1.40, 95% CI 1.03–1.90) while an inverse trend with oral semaglutide (RR 0.43, 95% CI 0.21–0.87).

Why this rating

Meta-analysis of RCTs, but sensitivity analysis showed significance was driven by specific large trials (REWIND, PIONEER-6).
