Implication

ST depression and elevation associate with multivessel disease and LV aneurysm post-MI; leaves open utility for risk stratification or management decisions.

Structured PICO

Can ST segment changes during exercise testing predict multivessel coronary disease and left ventricular aneurysm in patients after a single myocardial infarction?

P
Population
154 patients with a single documented myocardial infarction who had both exercise testing and coronary angiography
I
Intervention
Exercise testing with evaluation of ST segment changes (ST depression ≥1 mm, ST elevation ≥1 mm, both, or neither)
O
Outcome
Presence of multivessel coronary disease (≥70% luminal narrowing in two or more coronary vessels) and left ventricular aneurysmsurrogate

ST depression during exercise testing post-MI strongly predicts multivessel coronary disease, whereas ST elevation predicts the presence of a left ventricular aneurysm.
