Exercise testing early after myocardial infarction. Risks and benefits

Abstract

Submaximal exercise testing in the early weeks following myocardial infarction appears to be safe in selected patient groups. Potential benefits of such testing includes: (1) promotion of patient self-confidence, (2) determination of post-hospital exercise prescription, (3) detection of arrhythmias, and (4) determination of post-hospital prognosis. However, the practical value of the apparent psychologic benefits and of the exercise prescription information in a patient not participating in formal exercise rehabilitation therapy is unclear. Detection of potentially important arrhythmias appears to be more adequately effected with 24-hour ambulatory electrocardiography, and detection of such arrhythmias appears to add relatively little prognostic information to that available from exercise electrocardiographic S-T analysis, or from resting radionuclide ejection fraction. Nonetheless, exercise-induced S-T segment depression can provide potentially useful prognostic information regarding morbid or fatal events during the year after infarction. Moreover, recent data suggest that exercise-induced angina and/or S-T segment depression can aid importantly in the noninvasive determination of the anatomic extent of coronary artery diseas...Continue Reading

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
