title: [Risk factors of vascular complications in patients at a predialysis stage of chronic renal failure].
abstract: OBJECTIVE
  To specify risk factors of vascular complications at a predialysis stage of renal failure.
  
  
  METHODS
  The trial enrolled 165 patients with chronic renal failure (CRF) aged 46 +/- 15 years, glomerular filtration rate (GFR) - 37.2 (35.02-40.83) and arterial hypertension (96%). The examination included ultrasound dopplerography of the common carotid arteries (CCA) and common femoral arteries (CFA) for detection of atherosclerotic plaques (AP), estimation of the thickness of arterial intima-media, elasticity and rigidity of the vascular wall. Factors of risk for atherosclerosis and cardiovascular complications were assessed.
  
  
  RESULTS
  Aortic atherosclerosis was detected in 60 patients, that of cardiac vessels, brain, kidneys and lower limbs - in 35, 30, 23 and 8 patients, respectively. Acute cardiovascular complications occurred in 13 patients. Main atherosclerosis risk factors were age, body mass index, systolic and pulse arterial pressure, disturbances of phosphorus-calcium metabolism. Structure and function of CCA and CFA were studied with dopplerography in 37 CRF patients. Increased intima-media thickness was associated with age, male sex, overweight, hypercholesterinemia, systolic and pulse arterial pressure. Body mass index, GFR, creatinin level were independent factors of intima-media thickness. Abnormal elasticity of CCA was related to hypertension, CFA - to hypercholesterolemia.
