Background: In patients with chronic renal failure (CRF), carotid artery intima media thickness (CAIMT) is increased when the patients are on hemodialysis. Vascular events caused by atherosclerosis are the major cause of death in patients undergoing hemodialysis. Aims: This study was done to find out the relationship between carotid artery intima media thickness and hemodialysis in chronic renal failure patients independent of classical risk factors and also the relationship between CAIMT of hemodialyzed patients and nonhemodialyzed CRF patients. Materials and Methods: In this observational study, CAIMT of 78 CRF patients was examined by B-mode ultrasonography. Glomerular filtration rate (GFR) was calculated by using the "Modification of Diet in Renal Disease" formula. CRF patients, who had been on regular hemodialysis treatment (treated thrice weekly) for at least 6 months, were identified as hemodialyzed patients. Data were analyzed by software Statistical package for the social Sciences (SPSS) (17 th version). Results: There was significant positive correlation between CAIMT and hemodialysis (P=0.045) independent of traditional risk factors. Hemodialyzed patients had higher mean CAIMT (1136.30±21.21 μm, P<0.001) than mean CAIMT of age and sex matched nondialyzed patients (959.30±23.01 μm). Conclusion: Hemodialysis is an independent risk factor for atherosclerosis in CRF patents. Hemodialyzed patients have significantly higher CAIMT than nondialyzed CRF patients.
