近年开展冠状动脉痉挛(CAS)冠状动脉(CA)造影检查以来,对 CAS 的研究较前迅速发展。发现 CAS 可发生于不同程度病变的 CA。不但可导致变异型心绞痛,也可造成典型和劳力型心绞痛。作者在对冠心病猝死临床病理研究中发现 CA 和心肌病变与猝死不成比例,曾提出可能因精神过劳等因索诱发 CAS 致急性心肌缺血,梗塞、室颤、猝死。CAS 缺乏病理形态标志。CA造影及诱发试验技术操作复杂,有一定的危险性。试图以临床、心电图、病理相结合避行研究,以便证实 CAS 的作用。
In recent years to carry out coronary artery spasm (CAS) coronary artery (CA) angiography since the CAS rapid development of the study. CAS found that lesions can occur in varying degrees of CA. Not only can cause variant angina can also cause typical and exertional angina. In the clinical pathological study of sudden death of coronary heart disease, the authors found that CA and cardiomyopathy were disproportionately caused by sudden death, suggesting that acute myocardial ischemia, infarction, ventricular fibrillation and sudden death may be induced by CAS because of mental overwork. CAS lack of pathological signs. CA angiography and induced test technique operation is complicated, there is a certain risk. Attempts to clinical, ECG, pathology combined with evasive research in order to confirm the role of CAS.
