Abstract:
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.
