Abstract:
Objective To investigate the effects of Sacubitril/Valsartan on amino terminal probrain natriuretic peptide (NT-proBNP),high sensitivity C-reactive protein (hs-CRP),soluble suppression of tumorigenicity 2(sST2)levels and on left ventricular(LV)structure in NYHA Ⅳ heart failure with reduced ejection fraction(HFrEF) patients.Methods A total of 67 HFrEF patients with NYHA Ⅳ were randomly divided into the control group (n =30)receiving conventional medical treatment,and the observation group(n=32)receiving Sacubitril/Valsartan instead of ACEI(or ARB if ACEI induced cough) in conventional medical treatment.NT-proBNP levels were determined by fluorescer-enhanced chemiluminescence.hs CRP levels were detected by latecx enhanced immunoturbidimetric assay.sST2 levels were determined by enzyme-linked immunosorbent assay (ELISA).The modified Simpson method was used to detect left ventricular end-diastolic diameter (LVEDD),LV posterior wall(LVPW)and LV ejection fraction(LVEF).Two groups of patients were treated and followed-up for 6 months.Results Clinical efficacy was better in the observation group than in the control group(effective rate,20 cases or 61.3％ vs.8 cases or 26.7％,P＜0.05).As compared with the control group,the observation group of patients had an increased LVEF[(46.7±9.2) ％ vs.(41.8±8.0)％,P＜0.05]and a decreased LVEDD[(52.6±6.7)mm vs.(58.8±7.5)mm,P＜0.05].After vs.before treatment,NT-proBNP,hs-CRP and sST2 levels were decreased in both control and observation groups [(1 427 ± 219) μg/L vs.(2 615 ± 273)μg/L,(1.14 ± 1.02) mg/L vs.(1.55±1.38)mg/L,(0.30±0.12)μg/L vs.(0.41±0.10)μg/L,all P＜0.05],and the decrements were much more in the observation group than in the control group (P＜0.05).The annual accumulated frequence and duration of hospitalization were less in the observation group than in the control group[(0.8±0.6)times vs.(1.8±1.0) times,(10.2±5.8)d vs.(16.5±7.2)d,P＜0.05].The maintenance dose of tolasemide was lower in the observation group than in the control group [(15.2±8.4)mg vs.(20.6±10.8)mg,P＜0.05].Conclusions Sacubitril/valsartan therapy is safe and effective and it can reduce hs-CRP and sST2 levels and improve the ventricular remodeling in HFrEF patients of HYHA Ⅳ.
