麝香保心丸对慢性缺血性心力衰竭患者心功能的影响

目的 探讨麝香保心丸对慢性缺血性心力衰竭患者心功能的影响.方法 96例临床症状稳定的慢性缺血性心力衰竭患者,随机分为麝香保心丸组(n=48)及安慰剂组(n=48),分别在西药治疗的基础上加用麝香保心丸或安慰剂治疗(2粒/次,3次/d,口服)24周,比较两组治疗前后左室射血分数(LVEF)、左室舒张末期容积(LVEDV)、血清脑钠肽(BNP)水平及6 min步行试验(6MWT)的变化.结果 两组患者一般资料之间差异无统计学意义.治疗24周后与治疗前比较,麝香保心丸组LVEF平均提高5.6％治疗前(34.2±3.5)％,治疗后(36.1±4.0)％,P＜0.05],血清BNP水平降低治疗前(680.2±203.9) pg/mL,治疗后(621.8±200.7) pg/mL,P＜0.05],6MWT距离增加治疗前(385.3士69.2)m,治疗后(401.7±75.0)m,P＜0.05],而LVEDV治疗前后差异无统计学意义(P＞0.05)；安慰剂组各指标治疗前后差异均无统计学意义(P＞0.05).结论 在西药治疗的基础上加用麝香保心丸能有效改善缺血性心力衰竭患者的心功能,是否能逆转左室重塑可能需要更长时间的观察.

Effect of Shexiangbaoxin pills on heart function in patients with chronic ischemia heart failure

Objective To investigate the effect of Shexiangbaoxin pills on the heart function of patients with chronic ischemia heart failure. Methods A total of 96 patients with documented stable chronic ischemia heart failure were evenly randomized into Shexiangbaoxin pill group (Shexiangbaoxin pill plus basic treatment) and placebo group (placebo plus basic treatment) for 24 weeks. The left ventricular ejection fraction (LVEF), left ventricular end diastolic volume (LVEDV), serum brain natriuretic peptide (BNP) level, and 6 minute walk test (6 MWT) were compared before and after treatment in the two groups. Results In Shexiangbaoxin pill group, the LVEF was increased by 5.6% after 24 weeks of treatment (\34.2±3.5\]% vs \36.1±4.0\]%, P<0.05), the serum BNP level was significantly decreased (\680.2±203.9\] pg/mL vs \621.8±200.7\] pg/mL, P<0.05), and the distance of 6MWT was significantly increased (\385.3±69.2\] m vs \401.7±75.0\] m, P<0.05); the LVEDV had no significance before and after treatment (P>0.05). The above parameters were not significantly different in placebo group before and after treatment (P>0.05). Conclusion Shexiangbaoxin pills plus basic treatment can effectively improve the left ventricular function in patients with chronic ischemia heart failure, and further study is needed to observe whether it can reverse left ventricular remodeling.
