摘要

Background: Pericardial fat is correlated with the occurrence of atrial fibrillation or coronary atherosclerosis. However, the role of pericardial fat in ventricular arrhythmia remains unclear. Methods and Results: Patients who had undergone dual-source computed tomography and 24-h Holter ECG were retrospectively enrolled. Quantification of the volume of pericardial fat surrounding the ventricles was analyzed using threshold attenuation of dual-source CT. The volume of pericardial fat was significantly different among those without ventricular premature beats (VPBs) in 24 h (n=28), those with occasional VPBs (n=54) and those with frequent VPBs (n=34) (12.5±6.1 cm3 vs. 14±8.9 cm3 vs. 29.9±17.3 cm3, P<0.001). In addition, the number of VPBs strongly correlated with the volume of total pericardial fat (R=0.501, P<0.001), right ventricular (RV) pericardial fat (R=0.539, P<0.001), and left ventricular pericardial fat (R=0.376, P<0.001). Multivariate logistic regression analysis showed that quartiles of RV localized pericardial fat significantly increased the risk of frequent VPBs (OR=3.2, P=0.047). Moreover, the number of VPBs in 24 h was significantly different among the patients with a fat volume within the 25th percentile, 25–75th percentile and 75th percentile. Conclusions: Pericardial fat (especially RV pericardial fat) was associated with the frequency of VPBs, which suggests the arrhythmogenic potential of ventricular pericardial fat.
