GLP-1 receptor agonists reduce the risk of atrial fibrillation by approximately 42% compared to placebo, which is a significant risk factor for stroke.
Taking GLP-1 drugs may also lower your risk of developing atrial fibrillation, a heart rhythm problem that increases stroke risk. This is another way these drugs protect your brain and heart.

In a meta-analysis including 11 RCT, semaglutide was shown to decrease the occurrence of incident AF by almost 42% compared to placebo [30].
Why this rating
Based on a meta-analysis of 11 randomized clinical trials.

- GLP-1 receptor agonists (GLP1RAs) reduce the risk of total stroke by approximately 16-17% and non-fatal stroke by 15-16% in patients with type 2 diabetes, independent of their effects on weight loss.Strong
- GLP-1 receptor agonists reduce systolic blood pressure by 1.7 to 10.6 mmHg compared to placebo, contributing to stroke risk reduction.Good

- Initial treatment for type 2 diabetes should be a combination of metformin and either an SGLT-2 inhibitor or a GLP-1 receptor agonist to achieve cardiorenal protection, rather than monotherapy or older agents like sulfonylureas.Strong
- For patients with specific monogenic obesity syndromes (leptin deficiency, POMC/PCSK1/LEPR mutations), targeted pharmacotherapy (recombinant leptin or setmelanotide) is highly effective and should be prioritized, unlike in polygenic obesity.Strong
- Continued weekly administration of 2.4 mg subcutaneous semaglutide prevents weight regain and promotes further weight loss in adults with overweight or obesity, whereas switching to placebo results in significant weight regain.Strong
