Prognostic Value of Exercise Testing: a 6-Year Follow-Up in Post-Myocardial Infarction Patients
Key result
ST-segment depression ≥2.0 mm at low effort predicts future mortality and non-fatal recurrent MI.
- n=112
Why the study?
The prognostic value of symptom-limited exercise testing in post-myocardial infarction patients over a long-term period was not well established.

Symptom-limited exercise testing within 3 months post-myocardial infarction, specifically ST-segment depression ≥2.0 mm at low effort, is a strong predictor of long-term mortality and recurrent infarction.
Cite This Study
Backer et al. (2008) conducted a cohort in Post-Myocardial Infarction (n=112). Symptom-limited exercise test (ST-segment depression ≥2.0 mm at low effort) was evaluated on Future mortality and non-fatal recurrent infarction. ST-segment depression of ≥2.0 mm at low effort and maximal exercise parameters during a symptom-limited exercise test were indicative of future mortality and non-fatal recurrent infarction.
