目的：探讨美托洛尔与常规方法在扩张型心肌病中的临床治疗效果。方法对66例扩张型心肌病患者资料进行分析，根据临床治疗方案不同将患者分为对照组和试验组。对照组患者采用常规药物治疗，试验组患者采用美托洛尔治疗，比较两组患者的治疗效果。结果试验组患者心率（HR）、C/T、收缩压（SBP）、舒张压（DBP）、左心室舒张末径（LVEDd）、左心室射血分数（LVEF）均低于对照组（均P＜0.05）；试验组患者日常生活活动能力评分、躯体功能评分、心理功能评分、社会功能评分均高于对照组（均P＜0.05）。结论给予扩张型心肌病患者采用美托洛尔进行治疗效果理想，能改善患者生活质量。“,”Objective To investigate the metoprolol and conventional methods in clinical treatment of dilated cardiomyopathy.Methods To hospital for treatment of 66 cases of dilated cardiomyopathy patients were analyzed, according to the different clinical treatment patients were divided into control and experimental groups.In the control group were treated with conventional drug therapy,the experimental group were treated with metoprolol treatment,the treatment effect between the two groups of patients.Results Heart rate test group(HR)index,C/T index,systolic blood pressure(SBP),diastolic blood pressure(DBP),left ventricular end-diastolic diameter(LVEDd),left ventricular ejection fraction(LVEF)were lower than the control group(P<0.05);activities of daily living in patients with experi- mental group scores,physical function score,mental function scores, social function scores were higher(P<0.05). Conclusion Give dilated cardiomyopathy patients using metoprolol treatment results are satisfactory,improve the quality of life of patients.
