Key result
Ambulatory ST segment monitoring at 1-3 months post-myocardial infarction is inferior to exercise testing for predicting cardiac events (21% vs 9% for positive vs negative exercise test, P<0.05).
Why the study?
Does ambulatory ST segment monitoring improve prognostic prediction compared with exercise testing in patients 1-3 months after acute myocardial infarction?
Population
177 patients at a mean of 38 days (range 22-93) post-myocardial infarction
Comparison

Design
Cohort
Follow-up
at least 1 year

Ambulatory ST monitoring adds no value over exercise testing for post-MI risk stratification; hypothesis-generating and should not yet change practice.

Does ambulatory ST segment monitoring improve prognostic prediction compared with exercise testing in patients 1-3 months after acute myocardial infarction?
Ambulatory ST segment monitoring is inferior to exercise testing for predicting prognosis 1-3 months after acute myocardial infarction and does not add predictive power.
CIRRIE et al. (1994) conducted a cohort in Acute myocardial infarction (n=177). Ambulatory ST segment monitoring vs. Exercise treadmill testing was evaluated on Cardiac events (myocardial infarction, cardiac death or coronary revascularisation). Ambulatory ST segment monitoring at 1-3 months post-myocardial infarction is inferior to exercise testing for predicting cardiac events (21% vs 9% for positive vs negative exercise test, P<0.05).
