title: Hypertriglyceridemic waist is associated with increased carotid atherosclerosis in chronic kidney disease patients.
abstract: BACKGROUND
  Patients with chronic kidney disease (CKD) have an unacceptably high risk of death, primarily as a result of cardiovascular disease (CVD). The 'hypertriglyceridemic waist' phenotype has been proposed as a simple and strong predictor of CVD risk. Therefore, we investigated the relationship between the hypertriglyceridemic waist phenotype and carotid atherosclerosis in CKD patients.
  
  
  METHODS
  In a cross-sectional study, we enrolled 785 prevalent CKD patients [416 males, aged 44.6 years (21.7-69.4), glomerular filtration rate 52.5 ml/min/1.73 m(2) (5.3-119.4)]. We divided the patients into three groups: group 1: waist circumference >90 cm in men or >85 cm in women and triglycerides ≥2 mmol/l (n = 109); group 3: waist circumference ≤90 cm in men or ≤85 cm in women and triglycerides <2 mmol/l (n = 379), and group 2: the remaining patients (n = 297). Routine biochemical parameters and carotid artery intima-media thickness (IMT) were measured.
  
  
  RESULTS
  The prevalence of the hypertriglyceridemic waist phenotypes was 13.8% in the CKD patients. Triglyceride, total cholesterol, HDL-cholesterol and LDL-cholesterol concentrations in group 1 were significantly higher than those in group 3. Carotid artery IMT of the hypertriglyceridemic waist group was the highest.
  
  
  CONCLUSIONS
  The hypertriglyceridemic waist phenotype was associated with worse carotid atherosclerosis in CKD patients. This suggests that the hypertriglyceridemic waist phenotype may be useful for predicting CVD risk in CKD patients.
