大量资料表明,应用β阻滞剂或钙离子拮抗剂能显著降低心绞痛患者胸痛的发作频率。在缓解心绞痛和改善运动能力方面,β阻滞剂与钙离子拮抗剂的联合应用比两药单独应用更为有效。慢性缺血性心脏病治疗的选择取决于识别主要的发病机理。无痛性心肌缺血:动态心电图监测提供了一个区别心绞痛不同发病机理的方法。有心绞痛主诉的患者,24h动态心电图记录显示,既有伴胸痛发作的ST段压低,也有相同数量的不伴胸痛的ST段压低。
A large number of data show that the application of beta blockers or calcium antagonists can significantly reduce the frequency of chest pain in angina patients. The combination of beta blockers and calcium antagonists is more effective than the two drugs alone in relieving angina and improving exercise capacity. The choice of treatment for chronic ischemic heart disease depends on the identification of the main pathogenesis. Painless Myocardial Ischemia: Holter monitoring provides a means of differentiating the different pathogenesis of angina. In patients with angina complaints, 24-hour Holter recordings showed both ST-segment depression with chest pain episodes and the same number of ST-segment depression without chest pain.
