目的观察益气化瘀冲剂治疗慢性舒张性心力衰竭的临床疗效。方法将120例慢性舒张性心力衰竭病人随机分为两组。试验组63例给予益气化瘀冲剂及西药规范诊疗方案:包括β受体阻滞剂、血管紧张素转换酶抑制剂(ACEI)或血管紧张素Ⅱ受体阻滞剂(ARB)、钙拮抗剂、利尿剂、硝酸酯类药物治疗。对照组57例给予西药规范诊疗方案治疗。观察两组治疗前后临床症状积分、6 min步行距离、脑钠肽(BNP)水平和左心室功能的变化情况。结果两组有效率分别为93.65%和82.46%,组间比较差异有统计学意义(P<0.05);试验组治疗后气促、胸闷、头晕、乏力和口唇紫暗的临床症状积分均明显降低,组间比较差异有统计学意义(P<0.05);试验组用药后6 min步行距离、BNP、左室舒张功能提高明显,组间比较差异有统计意义(P<0.05)。结论在常规西医治疗基础上联合益气化瘀冲剂治疗舒张性心力衰竭,疗效优于单纯西医治疗。
Objective To observe the clinical curative effect of Yiqi Huayu granule on chronic diastolic heart failure. Methods 120 patients with chronic diastolic heart failure were randomly divided into two groups. The experimental group of 63 cases given Yiqi Huayu granules and western medicine norms of treatment programs: including β-blockers, angiotensin converting enzyme inhibitor (ACEI) or angiotensin Ⅱ receptor blocker (ARB), calcium antagonist Agents, diuretics, nitrates treatment. The control group of 57 cases given Western standard treatment program for treatment. Clinical symptom score, 6-minute walk distance, BNP level and left ventricular function were observed before and after treatment. Results The effective rates of the two groups were 93.65% and 82.46%, respectively, and there was significant difference between the two groups (P <0.05). The scores of clinical symptoms in the experimental group after treatment were shortened, chest tightness, dizziness, fatigue and darkness of lips were significantly decreased (P <0.05). The walking distance, BNP and left ventricular diastolic function were significantly increased in the experimental group at 6 min after treatment, with significant difference between the two groups (P <0.05). Conclusion On the basis of routine western medicine, Yiqi Huayu Granule is effective in treating diastolic heart failure.
