目的观察尼卡地平联合多巴酚丁胺治疗难治性心力衰竭(RHF)的疗效。方法 46例 RHF 患者随机分为治疗组23例和对照组23例,两组均给予常规治疗。治疗组则在常规治疗的基础上再给予尼卡地平和多巴酚丁胺,1周为1疗程。观察两组治疗前后临床疗效及 SBP、DBP、HR、LVEF 的变化和不良反应。结果两组临床疗效比较:治疗组总有效率为91.3%,对照组为65.2%,差异有显著性意义(X~2=4.6,P<0.05);两组治疗前后 SBP、DBP、HR、及 LVEF 比较,差异均有显著性意义(P<0.01)。结论尼卡地平联合多巴酚丁胺治疗难治性心力衰竭有较好的疗效,且不良反应较少。
Objective To observe the efficacy of nicardipine combined with dobutamine in the treatment of refractory heart failure (RHF). Methods Forty-six patients with RHF were randomly divided into treatment group (23 cases) and control group (23 cases). Both groups were given routine treatment. The treatment group was given nicardipine and dobutamine on the basis of routine treatment, and the course of treatment was 1 week. The clinical efficacy and changes of SBP, DBP, HR, LVEF and adverse reactions in both groups before and after treatment were observed. Results The clinical efficacy of the two groups was 91.3% in the treatment group and 65.2% in the control group, with significant difference (X ~ 2 = 4.6, P <0.05). The SBP, DBP, HR, LVEF, the differences were significant (P <0.01). Conclusions Nicardipine combined with dobutamine can treat refractory heart failure with good curative effect and less side effects.
