Why the study?
Epicardial adipose tissue is related to atrial fibrillation, but its association with premature ventricular complexes remains unclear.
Is epicardial adipose tissue volume associated with an increased risk and higher burden of frequent premature ventricular complexes?
Is epicardial adipose tissue volume associated with an increased risk and higher burden of frequent premature ventricular complexes?
Increased epicardial adipose tissue volume is independently associated with a higher risk and greater burden of frequent premature ventricular complexes, suggesting a potential novel pathogenic mechanism.

May link higher EAT volume to frequent PVCs; hypothesis-generating and requires prospective validation before clinical use.
Background Epicardial adipose tissue (EAT) is related to atrial fibrillation. The association between EAT volume and premature ventricular complexes (PVCs) remains unclear. Our study aimed to investigate the effect of EAT volume on the risk of frequent PVCs and burden levels of PVCs. Methods This observational study retrospectively recruited consecutive patients who had consultation between 2019 and 2021 at the First Affiliated Hospital of Zhengzhou University. Frequent PVC patients ( n = 402) and control patients ( n = 402) undergoing non-contrast computed tomography (CT) were enrolled. We selected evaluation criteria for the conduct of a 1:1 propensity score matching (PSM) analysis. Multivariable logistic analysis was used to investigate factors related to frequent PVCs. Furthermore, the determinants of EAT volume and the burden levels of PVCs were evaluated. Results Patients with PVCs had a significantly larger EAT volume than control patients. EAT volume was significantly larger in male PVC patients with BMI ≥24 kg/m 2 , diabetes mellitus, and E/A ratio <1. EAT volume was independently associated with PVCs. Moreover, the larger EAT volume was an independent predictor for the high burden level of PVCs. We revealed that the risk of high PVC burden level was increased with the rising of EAT volume by restricted cubic splines. Conclusions EAT volume was larger in frequent PVC patients than in control patients, regardless of other confounding factors. A large EAT volume was independently associated with high burden levels of PVCs. EAT volume may be a new mechanism to explain the pathogenesis of PVCs.
