Effect of early correction of anemia with erythropoietin on left ventricular mass in predialysis patients: a multi-center trial

  • Objective To assess the effects of early correction of anemia with recombinant human erythropoietin (rHuEPO) on the develop-ment and progression of left ventricular hypertrophy (LVH) in patients with mild-to-moderate chronic renal insufficiency (CRI) who are not on hemodialysis. Methods A total of 158 patients with serum creatinine from 147jJ.mol/L to 40()p_mol/L were enrolled in this prospective, multicenter study. Eighty-six patients with hemoglobin (Hb) 1 lOg/L (Group A). Forty patients with comparable Hb concentration ( l lOg/L and without rHuEPO treatment (Group C) were served as controls. Left ventricular mass index (LVMI) was evaluated by echocardiography at baseline and every 3 months for 2 years. Results There was no difference in age, gender, etiology of renal failure, blood pressure and cardiovascular risk factors among the 3 groups. At baseline, the prevalence of LVH was 72.1% in group A, 72.5% in group B and 59.4% in group C. LVMI was inversely correlated with Hb levels (r=0.70, P<0.01). During the 2-year period, the mean LVMI decreased from 142.6±25.7g/m: to 132.4±18.5 g/nr in group A, while increased significantly in both group B and group C. The mean Hb concentration increased from 93.8±i4.6g/L to 111.2±10.3g/L (P<0.05) in group A, but tended to decrease in group B and group C. There was no significant change of the mean blood pressure, number of anti-hypertensive drugs and serum creatinine concentrations in all 3 groups. However, patients' serum creatinine doubled more often in group B and group C than in group A. Conclusions LVH was common in predialysis CRI patients and was associated with the severity of anemia. Early intervention with rHuEPO may reverse LVH in these patients.
