Evidence for dynamic coronary vasoconstriction of non-infarct vessels during acute myocardial infarction.
The role of coronary vasoconstriction in acute myocardial infarction is controversial. Two patients are presented who were studied with angiography during the early hours of acute myocardial infarction and in whom reversible spasm of non-infarct vessels was observed. A tendency towards coronary vasospasm may be a generalized phenomenon during acute myocardial infarction.
