Left ventricular remodeling in patients with chronic renal failure on outpatient hemodialysis

Abstract

Aim. To study left ventricular remodeling (LVR) in patients with end-stage renal disease (ESRD) treated by hemodialysis (HD). Material and methods. A total of 122 patients with ESRD were examined: 21 patients with predialysis ESRD (group 1), 37 patients treated by HD for 4 hours thrice a week (group 2), 64 patients treated by HD for 5 hours thrice a week (group 3). All the patients have undergone echocardiography. Blood serum hemoglobin, urea, creatinine, albumin, calcium, phosphates, PTH were measured. URR and Kt/V were calculated in patients of group 2 and 3. Results. LVM and ILVM were significantly higher in patients of group 2, excentric geometry predominated (63.2%). Conclusion. Prolongation of HD procedure from 4 to 5 hours thrice a week positively influences left ventricular remodeling and increases the survival of ESRD patients treated by HD.
