    Abstract:
    To evaluate determinants of left ventricular hypertrophy (LVH) and left ventricular (LV) systolic dysfunction in chronic renal failure (CRF), M-mode and two-dimensional echocardiography were performed in 38 undialyzed patients with CRF (serum creatinine > or = 3.4 mg/dL), 54 patients receiving continuous ambulatory peritoneal dialysis, 30 patients receiving hemodialysis, and 59 healthy age- and sex-matched volunteers. Left ventricular (LV) wall thickness and LV dimensions were greatest in dialysis patients, intermediate in CRF patients, and least in control subjects. LV mass index calculated from M-mode measurements was 78.7 g/m2 +/- 14.8 g/m2 in controls, 120.5 g/m2 +/- 28.7 g/m2 in CRF patients, and 136 +/- 45.0 g/m2 in dialysis patients (P < 0.0001). LV fractional shortening and LV velocity of circumferential shortening were lower in dialysis patients than in CRF patients and controls (fractional shortening 36.5% +/- 5.6% in controls, 36.2% +/- 7.2% in CRF patients, and 29.8% +/- 8.9% in dialysis patients; P < 0.0001). Echocardiography was normal in only 24 dialysis patients (29%) and 14 CRF patients (37%) (P = NS). Thirty-nine dialysis patients (46%) and 10 CRF patients (26%) had LVH (P = NS). Thirty dialysis patients (36%) and five CRF patients (13%) had LV systolic dysfunction (P < 0.05). LV hypertrophy with LV systolic dysfunction was present in 15 dialysis patients but no CRF patients (P < 0.05). There were no significant differences between hemodialysis patients and continuous ambulatory peritoneal dialysis patients in M-mode echocardiographic measurements or the frequency of LVH and LV systolic dysfunction.(ABSTRACT TRUNCATED AT 250 WORDS)
