Long-term prognosis of painless exercise-induced ischemia in stable patients with previous myocardial infarction.

Objectives: This study was designed to better understand the functional correlates and the prognostic relevance of exercise-induced painless ischemia relative to painful ischemia in patients with stable coronary artery disease and previous myocardial infarction (MI).

Background: The usefulness of exercise testing (ET) for predicting cardiac events, years after MI, although suggested and widely applied, is questionable. In particular, previous studies have reached conflicting conclusions as to whether exercise-induced painless ischemia is related to a less severe myocardial ischemia or to a different prognosis than painful ischemia.

Can exercise testing in patients with a history of myocardial infarction predict fatal and non-fatal reinfarction?

Background And Objectives: Exercise testing (ET) is the preferred initial strategy for risk stratification in patients who are able to exercise and have an interpretable electrocardiogram. However, although it is often suggested and widely applied, its usefulness years after myocardial infarction (MI) is questionable. Therefore, this study was designed to assess the value of exercise testing in predicting the risk of fatal or non-fatal reinfarction in patients with chronic stable coronary artery disease (CAD) due to old myocardial infarction.
