Although both sudden death and acute myocardial infarction are almost always associated with long-standing obstructive coronary artery disease, both may originate in the myocardium. Spasm has been suggested as a factor contributing to sudden death. Not all persons dying of acute myocardial infarction have narrowed coronary arteries, nor do all persons with obstructed arteries die of heart disease. The first phase of acute myocardial infarction may well involve myocardial necrosis, followed by stasis and collapse of collateral circulation and occasionally by coronary occlusion.
虽然猝死和急性心肌梗死几乎总是与长期存在的阻塞性冠状动脉疾病相关，但两者都可能起源于心肌。有人提出痉挛是导致猝死的一个因素。并非所有死于急性心肌梗死的人都有冠状动脉狭窄，也并非所有动脉阻塞的人都死于心脏病。急性心肌梗死的第一阶段很可能涉及心肌坏死，随后是侧支循环的淤滞和衰竭，偶尔还会出现冠状动脉闭塞。
