ABSTRACT

Objective:

To observe the clinical efficacy of Xiao Qinglongtang on chronic heart failure with cold phlegm in lung, and explore its mechanism of action.

Method:

A total of 87 patients with definite chronic heart failure were divided into observation group and control group by random number table method.The two groups received routine western medicine at the same time. Forty-two cases in observation group were treated with Xiao Qinglongtang based on western medicine, and 45 cases in control group received the same dose of placebo. Both groups were treated for 4 weeks, and then their cardiac function, traditional Chinese medicine (TCM) syndrome score and efficacy were compared before and after treatment. Left ventricular ejection fraction (LVEF) and N-terminal pro-brain natriuretic peptide (NT-proBNP) were measured in both groups before and after treatment. The changes of standard deviation of NN intervals (SDNN), square root of the mean squared differences of successive NN intervals (RMSSD), high frequency (HF) and low frequency (LF) that reflect autonomic nerve function indexes in heart rate variability (HRV) after treatment were compared between two groups. The changes of inflammatory indicators such as interleukin-6IL-6) and highly sensitive C reaction proteinhs-CRP) were detected.

Result:

After treatment, the total effective rate for cardiac function in observation group was higher than that in control group (P<0.05). The TCM symptom scores were improved after treatment in both groups (P<0.05), and the total effective rate in observation group was higher than that in control group (P<0.01). After treatment, LVEF levels significantly increased (P<0.01) and NT-proBNP levels significantly decreased (P<0.01) in both groups, and the effect in observation group was more obvious (P<0.01). After treatment, SDNN, RMSD, HF and LF indicators in HRV were all higher than those before treatment in both groups (P<0.01), and the improvement in observation group was more significant than that in control group (P<0.01). The levels of IL-6 and hs-CRP decreased after treatment in both groups (P<0.01), and the level of observation group was significantly lower than that of control group (P<0.01).

Conclusion:

Xiao Qinglongtang has certain clinical efficacy in treating chronic heart failure with cold phlegm in lung as it can improve the clinical symptoms of patients, regulate autonomic nervous balance, and inhibit inflammatory factors, providing new clinical ideas to treat chronic heart failure in TCM.
