摘要

Background: It is well-known that cardiovascular risk and all-cause mortality is increased in hemodialysis patients. Epicardial fat thickness (EFT), which reflects visceral adiposity, has been suggested as a new cardiometabolic risk factor. The purpose of this study was to investigate EFT in hemodialysis patients. Methods: A total of 144 consecutive patients (60 hemodialysis patients and 84 controls) were enrolled into the study, and patients with diabetes mellitus and cardiovascular diseases (CVD)were excluded. EFT was measured on the free wall of the right ventricle at end-diastole from the parasternal long-axis view by standard transthorasic 2D echocardiography. Results: The groups were similar in terms of sex distribution, age, blood pressure, heart rate and frequencies of CAD risk factors including smoking status, family history of CAD and hypertension. There were no significant differences between the hemodialysis patients and controls in 2D echocardiographic parameters, including ejection fraction and biochemical parameters except low-density lipoprotein, high-density lipoprotein and creactive protein. Despite having lower body mass index, EFT levels were significantly higher in hemodialysis patients compared to the controls (8.0±2.2 mm vs. 5.8±1.9 mm; p ＜ 0.01). In multivariate linear regression analysis we determined that hemodialysis patient status was found to be an independent predictor for both EFT (β = 0. 700, p = 0.014) and carotid intima-media thickness (CIMT, β = 0. 614, p = 0.047). Conclusions: Hemodialysis patients are independently associated with high EFT and CIMT.
