Abstract

BACKGROUND/OBJECTIVE: Recent epidemiological data have shown that abdominal fat accumulation is associated with increased risk of cardiovascular events in patients with chronic kidney disease (CKD). This study aimed to investigate the association between visceral adiposity and coronary artery calcification (CAC) in CKD patients. SUBJECTS/METHODS: Cross-sectional study with 65 nondialyzed CKD male patients (59 +/- 9 years, CKD stages 3 and 4). Abdominal fat compartments were assessed by computed tomography (CT) at L4-L5 level. Visceral to subcutaneous (V/S) fat ratio was calculated. Visceral obesity was defined as a V/S fat ratio greater than the median value of the sample study (>0.55). CAC was detected by multi-slice CT. CAC scores were calculated with the Agatston method. RESULTS: CAC was present (calcium score > 10 AU) in 66% of patients. In the group with visceral obesity, the CAC score was significantly higher. This group had lower adiponectin and higher leptin levels compared to patients without visceral obesity. In the whole sample, higher V/S fat ratio was associated with CAC score, independently of age, body mass index, diabetes, ionized calcium, smoking or renal function. CONCLUSION: Our results show an association between visceral obesity and CAC in CKD patients, suggesting a deleterious effect of visceral fat in these patients. Increased visceral adiposity might enhance cardiovascular risk in this particular population. (AU)
