目的观察射频消融术治疗心动过速性心肌病的临床效果。方法 82例心动过速性心肌病患者,随机分为观察组与对照组,各41例。对照组给予贝那普利、利尿剂、地高辛、胺碘酮口服治疗,观察组采用射频消融术治疗,对两组患者治疗前后的左心室舒张末期内径(LVEDD)、左心室射血分数(LVEF)、血浆N端脑钠肽前体(NT-pro BNP)水平以及心功能改善情况进行观察比较。结果治疗后两组LVEDD、LVEF及NT-pro BNP水平比较差异具有统计学意义(P<0.05);观察组患者心功能改善情况明显优于对照组,差异具有统计学意义(P<0.05)。结论射频消融术治疗心动过速性心肌病的临床疗效理想,优于药物治疗,值得在临床上推广与应用。
Objective To observe the clinical effect of radiofrequency catheter ablation in the treatment of tachycardia cardiomyopathy. Methods 82 cases of tachycardia cardiomyopathy patients were randomly divided into observation group and control group, 41 cases each. The patients in the control group were treated with benazepril, diuretic, digoxin and amiodarone. The patients in the observation group were treated with radiofrequency catheter ablation. The left ventricular end-diastolic diameter (LVEDD), left ventricular ejection fraction (LVEF), plasma N-terminal pro-brain natriuretic peptide (NT-pro BNP) levels and cardiac function were observed and compared. Results The LVEDD, LVEF and NT-pro BNP levels in the two groups after treatment were significantly different (P <0.05). The improvement of cardiac function in the observation group was significantly better than that in the control group, with statistical significance (P <0.05). Conclusion Radiofrequency catheter ablation is an effective method to treat tachycardia cardiomyopathy, which is superior to medical treatment and is worth popularizing and applying clinically.
