Low-level exercise testing early after AMI helps identify patients with a good 1-year prognosis, even when taking beta-blockers.
Cite This Study
Krone et al. (1987) conducted a cohort in Acute myocardial infarction (n=207). Low-level exercise testing was evaluated on Deaths from cardiac causes in the year after AMI. Low-level exercise testing identified 108 patients (52%) taking beta-blockers who had 0 deaths from cardiac causes in the year following acute myocardial infarction.
