目的分析β受体阻滞剂在治疗稳定型心绞痛时的作用与疗效评价。方法将稳定型心绞痛随机分为两组对照进行治疗,统计3个月与6个月两组发生不稳定型心绞痛与心律失常的情况。结果发生不稳定型心绞痛例数3个月治疗组5例,对照组14例,6个月治疗组6例,对照组24例;3个月治疗组出现10例心律失常,对照组出现20例。结论β受体阻滞剂对多数稳定型心绞痛患者治疗预后较好。 Objective To analyze the effect of β-blocker on the treatment of stable angina pectoris and evaluate its curative effect. Methods The patients with stable angina pectoris were randomly divided into two groups and the control group was treated. Statistically, unstable angina pectoris and arrhythmia were observed in both groups at 3 months and 6 months. Results The number of patients with unstable angina pectoris in 3 months was 5 in the treatment group, 14 in the control group, 6 in the 6-month treatment group and 24 in the control group; 10 in the 3-month treatment group and 20 in the control group .
