目的评估酚妥拉明联合多巴胺治疗42例难治性心力衰竭的临床疗效。方法选取84例难治性心力衰竭患者作为研究对象,按随机盲选法分为两组,对照组42例给予常规治疗,观察组42例给予酚妥拉明联合多巴胺治疗,比较两组临床治疗效果。结果治疗前心率、收缩压、舒张压两组比较差异未见统计学意义(P>0.05);治疗后,两组三项指标呈降低趋势,观察组降低趋势更显著(P<0.05);治疗前后左室射学分数,两组比较差异未见统计学意义(P>0.05)。观察组治疗总有效率为95.24%,高于对照组的71.43%,差异有统计学意义(P<0.05)。结论难治性心力衰竭患者给予酚妥拉明联合多巴胺治疗,疗效显著,值得采纳应用。
Objective To evaluate the clinical efficacy of phentolamine combined with dopamine in the treatment of 42 patients with refractory heart failure. Methods Eighty-four patients with refractory heart failure were enrolled in this study. Patients were divided into two groups according to the random blind selection method. In the control group, 42 patients were given conventional therapy. In the observation group, 42 patients were treated with phentolamine combined with dopamine. effect. Results Before treatment, heart rate, systolic blood pressure and diastolic blood pressure had no significant difference between the two groups (P> 0.05). After treatment, the three indicators of both groups showed a decreasing trend, and the observation group showed a more significant decreasing trend (P <0.05) Before and after left ventricular fractional radiography, the two groups showed no significant difference (P> 0.05). The total effective rate of observation group was 95.24%, which was higher than that of control group (71.43%), the difference was statistically significant (P <0.05). Conclusion Phentolamine combined with dopamine in patients with refractory heart failure has significant curative effect and is worthy of adoption.
