Abstract
Background
GLP-1 receptor agonists (GLP-1 RAs) have emerged as an effective therapeutic class for weight loss. However, the efficacy of these agents in reducing cardiovascular endpoints among patients living with obesity or overweight is unclear.
Methods
We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) comparing GLP-1 RAs versus placebo in patients with obesity or overweight. We searched PubMed, Cochrane, and Embase databases. A random-effects model was used to calculate risk ratios (RRs) and mean differences (MDs), with 95% confidence intervals (CIs).
Results
A total of 13 RCTs were included, with 30,512 patients. Compared with placebo, GLP-1 RAs reduced systolic blood pressure (MD − 4.76 mmHg; 95% CI − 6.03, − 3.50; p < 0.001; I2 = 100%) and diastolic blood pressure (MD − 1.41 mmHg; 95% CI − 2.64, − 0.17; p = 0.03; I2 = 100%). GLP-1 RA significantly reduced the occurrence of myocardial infarction (RR 0.72; 95% CI 0.61, 0.85; p < 0.001; I2 = 0%). There were no significant differences between groups in unstable angina (UA; RR 0.84; 95% CI 0.65, 1.07; p = 0.16; I2 = 0%), stroke (RR 0.91; 95% CI 0.74, 1.12; p = 0.38; I2 = 0%), atrial fibrillation (AF; RR 0.49; 95% CI 0.17, 1.43; p = 0.19; I2 = 22%), and deep vein thrombosis (RR 0.30; 95% CI 0.06, 1.40; p = 0.13; I2 = 0%).
Conclusions
In patients living with obesity or overweight, GLP-1 RA reduced systolic and diastolic blood pressure and the occurrence of myocardial infarction, with a neutral effect on the occurrence of UA, stroke, AF, and deep vein thrombosis.
