RESUMEN
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.

BACKGROUND: The impact of cancer on patients with atrial fibrillation (AF) on warfarin remains a topic of ongoing debate. METHODS: We performed a systematic review and meta-analysis exploring the effect of cancer in patients with AF on warfarin. We searched PubMed, Embase, and Cochrane for eligible trials. Random-effects model was used to calculate the risk ratios (RRs), with 95% confidence intervals (CIs). Statistical analyses were performed using RStudio version 4.2.3. RESULTS: Five trials comprising 90,572 patients were included, of whom 12,239 (13.5%) had a personal history of cancer. The patient population had an average age of 72.7 years and 59.6% were male. A history of cancer was associated with a significant increase in any bleeding (RR 1.33; 95% CI 1.15- 1.53; p<0.01). There were no significant differences between groups for stroke (RR 1.05; 95% CI 0.86- 1.29; p=0.61), major bleeding (RR 1.44; 95% CI 0.95-2.18; p=0.09), cardiovascular (CV) death (RR 0.91; 95% CI 0.59-1.41; p=0.67), myocardial infarction (MI) (RR 1.42; 95% CI 0.96-2.10; p=0.08), gastrointestinal (GI) bleeding (RR 1.74; 95% CI 0.77-3.92; p=0.18), or all-cause death (RR 1.57; 95% CI 0.99-2.49; p=0.06). CONCLUSION: Among patients with AF on warfarin, a history of cancer is associated with an increased risk of any bleeding, with no significant effect on stroke, major bleeding, CV death, MI, GI bleeding, and all-cause death.

BACKGROUND: The efficacy of adding ezetimibe to statin therapy for event reduction in patients with acute coronary syndromes (ACS) remains a topic of ongoing debate. METHODS: We performed a systematic review and meta-analysis of randomized controlled trials (RCTs) comparing ezetimibe plus statin versus statin monotherapy in patients with ACS. We searched PubMed, Embase, and Cochrane for eligible trials. Random-effects model was used to calculate the risk ratios (RRs), with 95% confidence intervals (CIs). Statistical analyses were performed using RStudio version 4.2.3. RESULTS: Six RCTs comprising 20,574 patients with ACS were included, of whom 10,259 (49.9%) were prescribed ezetimibe plus statin. The patient population had an average age of 63.8 years and 75.1% were male. Compared with statin monotherapy, ezetimibe plus statin significantly reduced major adverse cardiovascular events (MACE) (RR 0.93; 95% CI 0.90-0.97; p<0.01) and non-fatal myocardial infarction (RR 0.88; 95% CI 0.81-0.95; p<0.01). There was no significant difference between groups for revascularization (RR 0.94; 95% CI 0.88-1.01; p=0.07), all-cause death (RR 0.87; 95% CI 0.63-1.21; p=0.42), or unstable angina (RR 1.05; 95% CI 0.86-1.27; p=0.64). CONCLUSION: In this meta-analysis of patients with ACS, the combination of ezetimibe plus statin was associated with a reduction in MACE and non-fatal myocardial infarction, compared with statin monotherapy.

BACKGROUND: The impact of cancer on patients with atrial fibrillation (AF) on direct oral anticoagulants (DOACs) remains a matter of debate. METHODS: We conducted a systematic review and meta-analysis exploring the effect of personal history of cancer in patients with AF on DOACs. PubMed, Embase, and Cochrane databases were searched for relevant studies. We used the random-effects model to calculate the risk ratio (RR) and 95% confidence intervals (CIs). Statistical analyses were performed using RStudio version 4.2.3. RESULTS: A total of six studies were included, with 63,177 patients. The mean age was 74.0 years. In this population of individuals who had AF and took DOACs, a history of cancer was associated with a significant increase in major bleeding (RR 1.72; 95% CI 1.24-2.38; p<0.01), gastrointestinal (GI) bleeding (RR 2.11; 95% CI 1.25-3.57; p<0.01), and any bleeding (RR 1.54; 95% CI 1.39-1.70; p<0.01). Additionally, all-cause death was significantly higher in patients with AF and a history of cancer (RR 1.93; 95% CI 1.35-2.76; p<0.01). There was no significant difference between groups in stroke (RR 1.77; 95% CI 0.66-4.73; p=0.25), cardiovascular (CV) death (RR 0.84; 95% CI 0.57-1.23; p=0.36), or myocardial infarction (MI) (RR 1.21; 95% CI 0.82-1.79; p=0.34). CONCLUSION: Our findings suggest that major bleeding, GI bleeding, any bleeding, and all-cause mortality significantly increased in patients with AF on DOACs who have a personal history of cancer, as compared with those who do not.
