    Abstract:
    AIM: To study correlation between development of left ventricular hypertrophy (LVH) and remodeling of major arteries at a predialysis stage of chronic renal failure (CRF). MATERIAL AND METHODS: A total of 95 non-diabetic patients (48 males-51% and 47 females-49%) with stage I-III CRF entered the trial. A mean age of the patients was 46.7 years (95% CI 43.7-49.8 years). Glomerular filtration rate calculated by Cockrott-Gault formula was 37.7 ml/min (33.9-41.4 ml/min), blood creatinine level--2.9 mg/dl (2.6-3.2 mg/dl). Arterial hypertension (AH) was registered in 96% patients, smoking--in 40%, cardiovascular hereditary burden--in 54%, hyperlipidemia--in 66%, overweight--in 60%, anemia--in 34%, hyperphosphatemia--in 45%. Echocardiography, ultrasonic dopplerography of the common carotid arteries (CCA) and common femoral artery (CFA) were performed in 83 and 37 patients, respectively. RESULTS: LVH (LV myocardium mass index > 134 g/m2 for males and > 110 g/m2 for females) was detected in 37.3% patients. Concentric remodeling was recorded in 31.3%, concentric myocardial hypertrophy--in 19.1% patients, excentric hypertrophy--in 18.1%. Development of LVH was linked with age, high systolic and pulse blood pressure, marked renal dysfunction, anemia, elevated ESR and hyperphosphatemia. The presence of L VH correlated with increased thickness of intima-media complex (IMC) of CCA and CFA (r = 0.65, p < 0.01 and r = 0.51, p < 0.05, respectively). There was correlation between thickness of LV posterior wall and impairment of CCA elasticity (r = -0.42, p < 0.05). CONCLUSION: Patients with initial and moderate disorders of renal function frequently have LVH related to conventional and "renal" risk factors. A LV mass increase and structural-functional changes of major vessels strongly correlate.
