近年来认识到冠状动脉痉挛(CoronaryArtery Spasm,CAS)在缺血性心脏病的发病机理上可能起着较过去所设想的更为重要的作用,进一步弄清CAS所涉及的各种问题,将导致对缺血性心脏病更合理的预防和治疗。关于CAS的病理机制存在各种假说,但有确实论据的资料不多,很多问题仍待进一步研究。本文重点综述CAS和缺血 In recent years, it has been recognized that Coronary Artery Spasm (CAS) may play an even more important role in the pathogenesis of ischemic heart disease than was previously thought to be. Further understanding of the various problems involved in CAS will result in More reasonable prevention and treatment of ischemic heart disease. There are various hypotheses about the pathological mechanism of CAS, but there is not much data on the exact arguments. Many questions still need further study. This article focuses on CAS and ischemia
