    Abstract:
    AIM: To investigate remodeling of the heart in patients with predialysis phase of chronic renal failure (CRF). MATERIAL AND METHODS: Patients with predialysis phase of CRF (n = 61; serum creatinine 412.4 +/- 242.69 mumol/l), essential hypertension (EH) (n = 35) and healthy volunteers (n = 20) were assessed with echocardiography. The patients were not significantly different by the level of systolic and diastolic blood pressure, age and gender. RESULTS: Left ventricular mass index (LVMI) was increased in 53(86.9%) patients with CRF. LVMI was not different in patients with CRF and EH (189.9 +/- 71.35 vs. 165.0 +/- 41.83 g/m2; p = 0.3). Relative wall thickness was similar in patients with serum creatinine < 200 mumol/l and patients with more elevated serum creatinine (57.2 +/- 10.33 vs 58.31 +/- 13.33; p = 0.9). The ejection fraction lower than 50% was detected in 14(22.9%) patients with CRF. Multivariate regression analysis showed that LVMI was independently related to systolic blood pressure (p = 0.004) and level of hemoglobin (p = 0.004). Diastolic dysfunction (early and atrial peak filling velocities ratio < 1.0) was detected in 13(50%) from 26 investigated patients with CRF. The independent influence of hemoglobin on isovolumic relaxation time (p = 0.04) and early and atrial peak filling velocities ratio (p = 0.02) are shown. CONCLUSION: In patients with predialysis phase of CRF left ventricular hypertrophy (LVH) is extremely common including patients with mildly elevated serum creatinine. The treatment of patients with renal pathology and normal function must include measures not only to correct renal process but also to prevent development of LVH.
