目的:观察黄芪注射液联合常规西药治疗老年慢性充血性心力衰竭(CHF)心气虚、血脉瘀阻证的临床疗效。方法:将90例慢性CHF心气虚、血脉瘀阻证老年患者按随机数字表法分为观察组和对照组各45例。对照组给予常规西药治疗,观察组在对照组用药基础上联合黄芪注射液治疗。观察2组症状、体征,以及心功能的改善情况。结果:观察组治疗总有效率95.56%,高于对照组的82.22%(P<0.05)。治疗后,观察组心功能的改善情况优于对照组(P<0.05)。治疗前,2组左心室舒张末期容积(LVEDV)、左心室收缩末期容积(LVESV)和左心室射血分数(LVEF)比较,差异均无统计学意义(P>0.05)。治疗后,2组LVEDV、LVESV和LVEF均较治疗前改善,差异均有统计学意义(P<0.05);观察组LVEDV、LVESV和LVEF的改善情况均优于对照组,差异均有统计学意义(P<0.05)。结论:黄芪注射液联合常规西药治疗慢性CHF心气虚、血脉瘀阻证,能有效改善患者的症状、体征及心功能,疗效优于单纯使用常规西药治疗。
Objective: To observe the clinical effects of astragalus injection combined with routine western medicine in treating elderly patients with congestive heart failure and blood stasis syndrome of chronic congestive heart failure (CHF). Methods: 90 elderly patients with chronic heart failure and blood stasis syndrome were randomly divided into observation group and control group with 45 cases in each group. The control group was given conventional western medicine, and the observation group was treated with astragalus injection on the basis of the control group. The symptoms, signs and the improvement of cardiac function in 2 groups were observed. Results: The total effective rate of the observation group was 95.56%, which was higher than that of the control group (82.22%, P <0.05). After treatment, the improvement of cardiac function in observation group was better than that in control group (P <0.05). Before treatment, the left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume (LVESV) and left ventricular ejection fraction (LVEF) were not significantly different between the two groups (P> 0.05). After treatment, the LVEDV, LVESV and LVEF in both groups improved compared with those before treatment, the difference was statistically significant (P <0.05); the improvement of LVEDV, LVESV and LVEF in the observation group were better than the control group, the differences were statistically significant (P <0.05). Conclusion: Astragalus injection combined with conventional western medicine can effectively improve the symptoms, signs and cardiac function of patients with chronic heart failure and blood stasis syndrome. The curative effect is better than that of conventional western medicine alone.
