Exercise ST elevation warrants context-specific interpretation by prior MI status; extends correlative insights but leaves open prospective validation.
What is the correlation between exercise-induced ST-segment elevation and myocardial perfusion or coronary anatomy in patients with and without previous myocardial infarction?
Exercise-induced ST-segment elevation indicates severe transient ischemia in patients without prior myocardial infarction, but may reflect peri-infarctional ischemia or abnormal wall motion in those with prior infarction.
Dunn et al. (1980) studied this question.
