Coronary spasm can cause chest pain, and may even culminate in a myocardial infarction, but it is not often considered a cause of chest pain in the early postinfarction period. Three patients who had chest pain early (1 day to 3 weeks) after myocardial infarction were shown to have coronary spasm with ergonovine maleate provocation. Two patients had spasm in the coronary artery associated with the acute infarction; the third had spasm in a remote vessel. Two required intracoronary nitroglycerin to establish patency in the affected vessel. It is concluded that coronary vasospasm can result in postinfarction angina.
冠状动脉痉挛可引起胸痛，甚至可能最终导致心肌梗死，但在心肌梗死后早期，它通常不被认为是胸痛的原因。有3例在心肌梗死后早期（1天至3周）出现胸痛的患者，经马来酸麦角新碱激发试验显示存在冠状动脉痉挛。2例患者的冠状动脉痉挛发生在与急性梗死相关的血管；第3例患者的痉挛发生在远离梗死部位的血管。2例患者需要冠状动脉内注射硝酸甘油以恢复受累血管的通畅。得出的结论是，冠状动脉痉挛可导致梗死后心绞痛。
