LEFT VENTRICULAR HYPERTROPHY IN PATIENTS ON CHRONIC HAEMODIALYSIS

Abstract

Left ventricular hypertrophy (LVH) is one of the main complication in patients on chronic haemodialysis. We observed high left ventricular mass index (LVMI) – 175,8 ± 6,4 g/m2 – in patients with substantial (>8 L) overhydration at the beginning of dialysis treatment and its reduction to 112,0 ± 7,2 g/m2 after removing of excessive fluid. In stable dialysis patients LVMI correlated with interdialysis weight gain (r = 0,79). In patients with interdialysis overhydration more, than 5% body mass, worsening of LVH was observed. On the contrary, regression of LVMI was registered in patients with moderate overhydration (<4,5% body mass). Patients with adequate intravascular refilling during dialysis session (with minor decline of relative blood volume per one L of ultrafiltration) were noncompliant concerning fluid restriction more frequently.
