Semaglutide significantly reduced cardiovascular events in overweight or obese adults without diabetes. This study shows semaglutide
Area of Science:
- Cardiology
- Endocrinology
- Pharmacology
Background:
- Semaglutide, a GLP-1 receptor agonist, is known to reduce cardiovascular events in diabetic patients.
- Its effect on cardiovascular risk in overweight/obese individuals without diabetes remains unestablished.
Purpose of the Study:
- To investigate the efficacy of semaglutide in reducing cardiovascular events in patients with overweight or obesity but without diabetes.
Main Methods:
- A multicenter, double-blind, randomized, placebo-controlled trial.
- 17,604 patients aged 45+ with cardiovascular disease and BMI ≥27 (no diabetes) received weekly subcutaneous semaglutide (2.4 mg) or placebo.
- Primary endpoint: composite of cardiovascular death, nonfatal myocardial infarction, or nonfatal stroke.
Main Results:
- Semaglutide group: 6.5% experienced a primary endpoint event vs. 8.0% in the placebo group (HR 0.80; P<0.001).
- Adverse events led to discontinuation in 16.6% of the semaglutide group vs. 8.2% in the placebo group.
Conclusions:
- Weekly semaglutide (2.4 mg) significantly reduced major adverse cardiovascular events in overweight/obese patients without diabetes.
- The findings support semaglutide's role in cardiovascular risk reduction beyond glycemic control.

GLP-1, when administered in high doses intravenously, triggers insulin secretion, inhibits glucagon release, slows gastric emptying, reduces food intake, and restores normal insulin secretion. However, its rapid inactivation by...
