目的观察倍他乐克治疗心脏X综合征(CSX)的疗效。方法72例X综合征患者随机分为硝酸酯和阿司匹林常规治疗组(对照组)36例,常规治疗加倍他乐克治疗组(治疗组)36例,服药10周,观察典型心绞痛发作频率、心电图运动实验变化。结果与对照组比较,治疗组CSX的心绞痛发作频率减少,心电图运动实验结果改善、差异均有统计学意义(P<0.05),与治疗前比较,治疗组治疗后CSX患者心绞痛发作频率和心电图运动实验结果比较差异均有统计学意义(P<0.05)。结论硝酸酯和阿司匹林加服倍他乐克治疗CSX疗效显著。
Objective To observe the efficacy of metoprolol in the treatment of cardiac X syndrome (CSX). Methods Seventy-two patients with syndrome X were randomly divided into three groups, 36 cases in the conventional treatment group (control group) and nitroglycerin and aspirin group, 36 cases in the conventional treatment group treated with metoprolol (treatment group) for 10 weeks. The frequency of typical angina pectoris, electrocardiogram Exercise experiment changes. Results Compared with the control group, the frequency of angina pectoris and the results of electrocardiogram exercise were decreased in the treatment group (P <0.05). Compared with the control group, the incidence of angina pectoris and electrocardiogram The experimental results were statistically significant differences (P <0.05). Conclusion Nitrates and aspirin combined with Betaloc to treat CSX have a significant effect.
