The physiologic basis for early ambulation after myocardial infarction.

Early ambulation is a recommended component of care for appropriately selected patients with uncomplicated myocardial infarction, which is feasible, safe, and cost-effective. Benefits of this approach include the prevention of cardiovascular "deconditioning" and other complications of prolonged bed rest, the prevention or reduction of anxiety and depression, the enhancement of physical work capacity and of self-image and self-confidence at the time of hospital discharge, and the lessening of total disability as assessed at followup examination. Economic advantages to be derived are those of permitting a shorter hospitalization, a more effective hospital bed utilization, and an earlier and more complete return to work.
