ABSTRACT

Objective To observe the effect of Huoxue-Yixin decoction combined with atorvastatin on NT-pro and QTd in patients with chronic heart failure (CHF). Methods A total of 120 patients with chronic heart failure in our hospital from December 2016 to June 2017 were enrolled in this study. The subjects were randomly divided into the control group (n=60) and the treatment group (n=60). The control group were treated with conventional treatment,and the treatment group were treated with Huoxue-Yixin decoction combined with atorvastatin. The two groups were treated for 30 days. The NT-ProBNP, QTd, QTcd and LVESD, LVEDD, LVEF of the two groups before and after treatment were compared.Results The QTd at 2 d(45.6 ± 8.9 ms vs.64.0 ± 18.2 ms,t=-7.029),14 d(44.3 ± 6.8 ms vs.55.7 ± 12.8 ms,t=-6.092)in the experiment group were significantly lower than those of control group(P<0.01).The level of QTcd at 2 d(50.8 ± 10.1 ms vs.71.2 ± 19.8 ms,t=7.109), 14 d(48.1 ± 9.7 ms vs.63.1 ± 13.1 ms,t=7.128)of the experiment group were significantly lower than those of control group(P<0.01).After treatment,the NT-ProBNP(494.58 ± 331.61 ng/L vs.594.71 ± 382.65 ng/L,t=-1.532), LVESD(40.23 ± 3.13 mm vs.49.72 ± 3.99 mm,t=-14.495)and LVEDD(58.22 ± 3.30 mm vs.65.11 ± 3.95 mm, t=-10.720)of the treatment group were significantly lower than those of the control group(P<0.01).The LVEF (69.82% ± 4.72% vs. 50.34% ± 4.02%, t=-10.720) of the treatment group was significantly higher than the control group(P<0.01).Conclusions The Huoxue-Yixin decoction combined with atorvastatin can reduce the level of NT-ProBNP, QTd and QTcd in patients with CHF, can significantly improve cardiac function.
