目的探讨盐酸胺碘酮片联合酒石酸美托洛尔片治疗心力衰竭伴室性期前收缩的临床疗效。方法选取2013—2014年迁西县人民医院收治的慢性心律失常伴室性期前收缩患者104例,采用计算机产生随机数字分为对照组53例与观察组51例。对照组患者予以盐酸胺碘酮片治疗,观察组患者在对照组基础上加用酒石酸美托洛尔片治疗。观察两组患者治疗前后静息时心室率、左室射血分数(LVEF)、左室舒张末期容积(LVEDV)、左室收缩末期容积(LVESV)、临床疗效及不良反应发生情况。结果治疗前两组患者静息时心室率、LVEF、LVEDV、LVESV比较,差异无统计学意义(P>0.05),治疗后观察组患者静息时心室率、LVEDV、LVESV低于对照组,LVEF高于对照组,差异有统计学意义(P<0.05);观察组患者室性期前收缩临床疗效及心功能临床疗效优于对照组,差异有统计学意义(P<0.05);两组患者不良反应发生率比较,差异无统计学意义(P>0.05)。结论盐酸胺碘酮片联合酒石酸美托洛尔片治疗心力衰竭伴室性期前收缩的临床疗效显著,可改善患者心功能,且不良反应少。
Objective To investigate the clinical efficacy of amiodarone hydrochloride tablets combined with metoprolol tartrate tablets in the treatment of heart failure with premature ventricular contraction. Methods A total of 104 patients with chronic cardiac arrhythmia and ventricular premature contractions admitted to Qianxi County People’s Hospital from 2013 to 2014 were selected and randomly divided into control group (53 cases) and observation group (51 cases). Patients in the control group were treated with amiodarone hydrochloride tablets. Patients in the observation group were treated with metoprolol tartrate tablets on the basis of the control group. The ventricular rate at rest, left ventricular ejection fraction (LVEF), left ventricular end-diastolic volume (LVEDV) and left ventricular end-systolic volume (LVESV) were observed before and after treatment in both groups. The clinical efficacy and adverse reactions were observed. Results There was no significant difference in ventricular rate, LVEF, LVEDV and LVESV between the two groups before treatment (P> 0.05). After treatment, the resting ventricular rate, LVEDV and LVESV in the observation group were lower than those in the control group (P <0.05). The clinical curative effect and clinical efficacy of ventricular premature ventricular contraction in the observation group were better than those in the control group (P <0.05), and the difference was statistically significant The incidence of adverse reactions, the difference was not statistically significant (P> 0.05). Conclusion Amiodarone hydrochloride tablets combined with metoprolol tartrate tablets in the treatment of heart failure with premature ventricular contraction clinical efficacy was significant, can improve cardiac function in patients with less adverse reactions.
