Abstract:
Objective To investigate the effects of benazepril on plasma copeptin and N terminal brain natriuretic peptide (NT-proBNP) in the patients with chronic heart failure (CHF) in order to explore the mechanism of benazepril on ventricular remodeling.Methods Two hundred and thirty-eight patients with CHF were randomized into control group (n =118) and therapy group (n =120).Patients in control group were received regular treatment including medicine of treating cardiotonic diuretic and vasodilator for 6 months,while in therapy group were given benazepril beside regular treatment.The levels of copeptin,NT-proBNP were measured before and after treatment.The left ventricular ejection fraction (LVEF),left ventricular end systolic diameter(LVESD) and left ventricular end diastole diameter(LVEDD) were recorded and compared before and after treatment.Results In treatment group,the levels of copeptin and NT-pro BNP,LVEF,LVEDD,LVESD were (4.9 ± 1.3) pmol/L and (327.8 ± 226.8) ng/L,(33.5 ± 6.2) ％,(47.6 ± 8.9) mm,(60.2 ± 7.1) mm before treatment,different from that after treatment ((17.8 ± 7.9) pmol/L,t =7.331,P =0.008 ; (1 779.6±838.3) pg/mL,t =10.236,P =0.002; (50.5 ±5.2)％,t =3.336,P=0.009;(32.9 ±5.7) mm,t =2.767,P =0.010 ; (43.2 ± 5.6) rmm,t =2.882,P =0.009).After treatment the levels of copeptin,NT-proBNP,LVEF,LVESD and LVEDD in treatment were lower than that of control group(control group:copeptin:(10.5 ± 2.4) nmol/L; NT-proBNP:(1076.6 ± 486.6) pg/L; LVEF:(36.6 ± 5.6) ％ ; LVESD:(45.9 ± 6.8)mm; LVEDD:(57.5 ± 5.4) mm),and there was significant difference between groups (P =0.049,0.010,0.035,0.038,0.048 respectively).Conclusion Benazepril treatment could decrease the level of plasma copeptin and NT-proBNP in CHF patients,inhibit neuroendocrine and the ventricular remodeling,and then improve the heart function.
