REACTIONS OF SYMPATHOVAGAL BALANCE IN ACUTE PHARMACOLOGICAL ASSAY AND EFFICIENCY OF ENALAPRIL MALEAT THERAPY OF A HEART FAILURE

The important condition of treatment of the patients with a heart failure (HF) is the normalization of a neu-rogumoral regulation (NGR) under action of medicinal therapy, and first of all, by ACE-inhibitors. Heart rate vari-ability (HRV) is a technique qualitatively estimating work of NGR. The efficiency of enalapril maleat (EM) thera-py of the patients with HF on its influence on clinical parameters and HRV was estimated depending on reaction LF/HF HRV in acute pharmacological assay (APA) with this preparation. Prior to the beginning treatment to the patients was spent APA with EM with registration of parameters HRV before reception and at height of action of a preparation. By its results of the patients have shared into two groups: group 1 with increase LF/HF, and group 2 with decrease LF/HF in APA. Within 3 months all patients received EM, nitroglycerinum and hydrochlorthia-zidum, then estimated changes in a clinical-functional condition of the patients and parameters HRV. The results show, that the clinical efficiency of EM is more effective at of decrease reaction of sympathovagal balance on APA with this preparation, is especial at the persons with III NYHA class. At rising LF/HF on APA results of treatment are less essential. The reaction of ТР in reply to therapy is higher in group of the patients with decrease LF/HF in APA, that reduces risk of development of fatal complications.
