经过近10年的精心研究已明确,冠状动脉痉挛与心绞痛有重要关系。目前,人们仍把心绞痛分为冠血管痉挛型心绞痛(VA)和典型的劳累型心绞痛两类。钙拮抗剂对预防VA发作的显著疗效已得到了普遍承认。然而,与冠状动脉痉挛和心肌梗塞(MI)、心绞痛的关系及其治疗方面的研究所取得的进展相比,对其预后及影响预后的危险因素方面,目前还了解得很少。影响典型的劳累型心绞痛预后的主要因素 After nearly 10 years of careful study has clearly that coronary artery spasm and angina have an important relationship. Angina is still classified as coronary vasospasm (VA) and classic exertional angina. The significant effect of calcium antagonists on preventing VA attacks has been generally acknowledged. However, little is known about the prognosis and the risk factors that influence the prognosis of coronary artery spasm and myocardial infarction (MI), angina pectoris and the treatment progress. The main factors affecting the prognosis of typical exertional angina pectoris
