本文提出了冠状动脉痉挛(简称冠弥痉挛)的定义:冠脉造影能见到大的心外膜分支出现一时性的、可逆的、次全或完全性狭窄为特征,同时伴有心肌缺血的某些表现,后者包括:①胸痛;②S-T 段抬高或压低;③心室舒张末期压力升高;④左心室运动障碍或运动减弱;⑤心肌乳酸产生;⑥一时性的~(201)铊灌注显影缺损。Masen 等报道了76例不稳定型心绞痛患者,在发作时所作血液动力学监测和~(201)铊心肌闪烁扫描或冠脉造影,均证实其起因是冠脉痉挛。不稳定型心绞痛中的一个特别类型是变异型心绞痛,这类患者会发生与劳力无关的持续和严重的心绞痛并其有特征性的临床标志——S-T 段抬高。应用硝酸甘油后,冠脉造影图完全恢复正常。Oliva 等研究了15例急性心肌梗塞患者,其中6例证实有冠脉痉挛。Masen 等提出,在梗
This paper presents the definition of coronary spasm (coronary spasm): coronary angiography can be found in large epicardial branches appear transient, reversible, sub-total or complete stenosis as characterized by myocardial ischemia The latter include: ① chest pain; ② S-T segment elevation or depression; ③ end-diastolic pressure; ④ left ventricular dyskinesia or exercise decreased; ⑤ myocardial lactic acid; ⑥ temporary Thallium perfusion development defect. Masen et al reported 76 patients with unstable angina pectoris, hemodynamic monitoring and ~ (201) thallium myocardial scintigraphy or coronary angiography at the time of the episode, all of which confirmed the cause of coronary spasm. A special type of unstable angina is variant angina, a type of patient that develops persistent and severe angina unrelated to labor and has a characteristic clinical marker of elevated S-T levels. After the application of nitroglycerin, coronary angiography completely returned to normal. Oliva et al studied 15 patients with acute myocardial infarction, of which 6 confirmed coronary artery spasm. Masen et al. Propose that in the stems
