To conduct a systematic review and meta-analysis on the crude and adjusted associations between epicardial adipose tissue (EAT) volume determined by computed tomography (CT) and coronary artery disease (CAD). MEDLINE, Scopus, and Web of Science databases were screened for all observational studies assessing the association between EAT volume and CAD. We calculated pooled odds ratio (OR) or hazard ratio (HR) and 95% confidence intervals (CI) for the association per 10 cm3 variation of EAT by five different definitions of CAD: obstructive or significant coronary stenosis (luminal narrowing ≥50% and ≥70%, respectively), presence of coronary artery calcification (CAC), myocardial ischaemia, and major adverse cardiovascular events (MACE) using DerSimonian and Laird random-effects models. Seventy studies were identified comprising 41 534 subjects, mainly derived from community-based or hospital-based low-to-intermediate pretest probability of CAD populations. Participants with any outcome of CAD had a higher mean volume of EAT than those without. Accordingly, the analysis of crude associations showed that EAT volume was associated with obstructive stenosis, significant stenosis, any CAC, and MACE. Based on the analysis of adjusted associations, although attenuated, EAT volume remained associated with obstructive stenosis (OR 1.055, 95% CI 1.033-1.078; I2 = 63.5%), significant stenosis (OR 1.514, 95% CI 1.262-1.815; I2 = 51.8%), myocardial ischaemia (OR 1.062, 95% CI 1.006-1.122; I2 = 86.9%), and MACE (HR 1.040, 95% CI 1.024-1.056; I2 = 64.7%) but was only borderline significant with CAC (OR 1.007, 95% CI 1.000-1.011; I2 = 75.8%). In low-to-intermediate cardiovascular risk subjects, EAT volume was independently associated with coronary artery stenosis, myocardial ischaemia, and MACE.

Aim Glucagon‐like peptide 1 receptor agonists (GLP1‐RA) reduce atherosclerotic events in patients with type 2 diabetes (T2D) and a high cardiovascular risk. The effect of GLP1‐RA to reduce heart failure (HF) has been inconsistent across T2D trials, and individual trials were underpowered to assess the effect of GLP1‐RA according to HF history. In this meta‐analysis we aim to assess the effect of GLP1‐RA in patients with and without HF history in stable ambulatory patients with T2D. Methods Random‐effects meta‐analysis of placebo‐controlled trials. The hazard ratio (HR) and 95% confidence intervals (95% CI) were extracted from the treatment effect estimates of HF subgroup analyses reported in each individual study. The primary outcome was a composite of HF hospitalization or cardiovascular death. Results In total, 54 092 patients with T2D from seven randomized controlled trials were included, of whom 8460 (16%) had HF history. Compared with placebo, GLP1‐RA did not reduce the composite of HF hospitalization or cardiovascular death in patients with HF history: HR 0.96, 95% CI: 0.84‐1.08, but reduced this outcome in patients without HF history: HR 0.84, 95% CI: 0.76‐0.92. GLP1‐RA did not reduce all‐cause death in patients with HF history: HR 0.98, 95% CI: 0.86‐1.11, but reduced mortality in patients without HF history: HR 0.85, 95% CI: 0.79‐0.92. GLP1‐RA reduced atherosclerotic events regardless of HF history: HR 0.85, 95% CI: 0.75‐0.97 with HF, and HR 0.88, 95% CI: 0.83‐0.93 without HF. Conclusions Treatment with GLP1‐RA did not reduce HF hospitalizations and mortality in patients with concomitant T2D and HF, but may prevent new‐onset HF and mortality in patients with T2D without HF. The reduction of atherosclerotic events with GLP1‐RA was not influenced by HF history status.
