Exercise training in heart failure: inpatient and outpatient considerations.

Exercise training has become increasingly important in the treatment of heart failure patients. It has long been known that the exercise tolerance of a patient with heart failure is related to his or her morbidity and mortality. Recently, it has been proved that exercise training improves cardiorespiratory function, functional status, and psychosocial status of heart failure patients. It is unknown whether these improvements will improve morbidity and mortality but quality of life appears to be enhanced. Subtle improvements in these areas may lead to a more satisfying and productive life for many heart failure patients. However, further investigation of the specific effects of such improvements is needed.
