目的观察老年人心力衰竭使用肌氨肽苷注射液的临床疗效及血浆脑钠肽(BNP)的浓度变化。方法临床病例120例,随机设常规治疗组与常规治疗加肌氨肽苷组,观测两组临床疗效及血浆脑钠肽浓度进行比较。结果常规治疗组与加肌氨肽苷组疗效差异有统计学意义及脑钠肽浓度变化也有明显差异。结论肌氨肽苷治疗老年人心力衰竭有确切疗效。 Objective To observe the clinical efficacy and the concentration of plasma brain natriuretic peptide (BNP) in elderly patients with heart failure treated with muscle aminopeptidase. Methods A total of 120 clinical cases were randomly divided into routine treatment group and conventional treatment plus muscle glycosides group. The clinical efficacy and concentration of plasma brain natriuretic peptide in the two groups were compared. Results There was significant difference in the curative effect between the conventional treatment group and the plus aminoglycoside group and the significant difference in the concentration of the brain natriuretic peptide. Conclusion Aminopeptidase treatment of heart failure in the elderly have the exact effect.
