Abstract

PURPOSE
Carotid artery intima-media thickness (cIMT) has been reported as the predictive factor of mortality of cardiovascular disease in dialysis patients but only a few reports are available on the patients with earlier stages. We compared cIMT according to the stage of chronic kidney disease, and analyzed the data in association with cardiovascular risk factors.
METHODS
Study subjects were 88 patients with chronic kidney disease less than 60 ml/min/1.73m2 of glomerular filtration rate. cIMT was measured by means of high- resolution B-mode ultrasonography. Cardiovascular risk factors and cIMT were analyzed and compared with 30 subjects with normal renal function.
RESULTS
cIMT was significantly increased with the stage of chronic kidney disease. When the stage was increased from 3 to 5, cIMT was increased (p=002). cIMT was further increased in all stages of chronic kidney disease than in patients with normal kidney function. But association of diabetic chronic kidney disease with non-diabetic chronic kidney disease was not significant (p=0.127). Multiple regression analysis showed that cIMT in patients with chronic kidney disease was significantly correlated to age, glomerular filtration rate, and the stage of chronic kidney disease.
CONCLUSION
We suggest that carotid atherosclerosis could increase in no dialysis patients with early stage of chronic kidney disease. Carotid artery intima-media thickness was correlated with age, glomerular filtration rate, and the stage of chronic kidney disease.
