BACKGROUND: Left ventricular hypertrophy (LVH), which strongly predicts cardiac mortality, is seen in more than 60% of end-stage renal disease patients. The aim of this study was to prospectively investigate the effect of salt restriction and strict volume control on blood pressure and LVH. METHOD: Nineteen hypertensive patients on chronic hemodialysis (HD) treatment (age 52 +/- 17 years, 7 women) were included in the study. Treatment consisted of 12-h HD per week, during which as much ultrafiltration (UF) was applied as possible without an excessive blood pressure (BP) drop. Special attention was given to dietary salt restriction. Predialysis mean BP (MBP), body weight (BW), cardio-thoracic index (CTI) and echocardiographic results were recorded at baseline and after 6 and 12 months. RESULTS: All patients reached acceptable BP (< 140/90 mmHg) within three months (10-75 days) with our strict volume control strategy. Mean pre-dialysis BP was 127 +/- 17/78 +/- 9 mm Hg at baseline, 120 +/- 9/75 +/- 6 mm Hg at the 6th month and 118 +/- 11/73 +/- 5 mm Hgat the 12th month. The incidence of symptomatic hypotension gradually decreased from a mean of 22% to 11% and 7%, respectively during follow-up. Left ventricular mass index decreased from 164 +/- 64 to 112 +/- 36 g/m2. CTI, left atrial, left ventricular systolic and diastolic diameters significantly decreased in all patients. Inter-dialytic weight gain was 930 +/- 70 g/day in the follow-up period. Hematocrit did not significantly differ at the first, second and last visits. CONCLUSION: Normal BP and improvement of cardiac structure, in particular a reduction of LVH could be reached in all our patients by intensifying salt restriction and UF.
