Application of Methods of Renal Replacement Therapy for Abolishment of Hyperhydration in Patients With Decompensated Chronic Heart Failure

Slow continuous ultrafiltration (SCUF), continuous veno-venous haemofiltration (CVVHF) are alternative to diuretics methods of treatment of patients with chronic heart failure (CHF), edematous syndrome. Methods. Patients of both sexes aged 30-82 years with functional class IIAIV CHF were included because of decompensation of CHF. Randomization: experiment - 19 patients, 3-4 component therapy plus SCUF or CVVHF; control - 3-4 component therapy plus intravenous furosemide. Examination: I (n) over tilde at baseline, II (n) over tilde after compensation of CHF. Results: Delta weight (kg) - experiment -10.1+/-1.08, control -1.92+/-0.83, p=0.00001; Delta left ventricular ejection fraction - experiment +10.09+/-2.26, control +0.52+/-1.14, p=0.0007; Delta pulmonary artery systolic pressure (mm Hg) - experiment -12.32+/-3,43, control -4.05+/-2.07, p=0.029; Delta 6-min walk test: experiment +304.22+/-39.4, control +91.91+/-23.4, p=0.00003; A glomerular filtration rate - experiment -1.16+/-3.23, control +4.44+/-3.68, p=0.85; duration of hospitalization (days) - experiment 17,26+/-1,43, control 17.52+/-1.02, p=0.59. We did not observe complications related to renal replacement therapy. Conclusion. SCUF and CVVHF are safe for patients. In decompensated CHF SCUF and CVVHF 'provide greater weight reduction and fluid removal than intravenous diuretics, abolish hypervolemia what cause improvement of myocardial contractility.
