心肌梗塞发病不久注入二硝酸异甘梨醇(ISDN)有效,说明心肌梗塞的发病同某种程度和形态的冠脉痉挛有关。Oliva等报告,对15例急性心肌梗塞发病不久的病人,向阻塞冠脉内注入硝酸甘油,6例疏通,因此,认为心肌梗塞的发病与冠状动脉痉挛有关。冠脉痉挛是心肌梗塞的原因还是结果,尚难判断。唯冠脉高度狭窄时,是先因冠脉痉挛引起血流受阻,而后形成冠脉血栓或因冠脉内膜胶原纤维先形成血栓,
Shortly after onset of myocardial infarction, isoprenol dinitrate (ISDN) is effective, indicating that the incidence of myocardial infarction is associated with some degree and form of coronary spasm. Oliva et al. Reported that in 15 patients with acute myocardial infarction, nitroglycerin was infused into blocked coronary arteries and 6 patients were unblocked. Therefore, it is believed that the incidence of myocardial infarction is related to coronary spasm. Coronary artery spasm is the cause of myocardial infarction or result, it is difficult to judge. The only narrow coronary arteries, is due to coronary artery spasm caused by blocked blood flow, and then the formation of coronary artery thrombi or coronary intimal collagen fibers to form a thrombus,
