Abstract
The safety and efficacy of cardiac rehabilitation or exercise training in patients with heart failure (HF) have been investigated during the decades. Because exercise intolerance and easy fatigue are important symptoms in these patients, the potential role of cardiac rehabilitation program including regular exercise has been emerged. In the current guideline for patients with HF due to reduced systolic function, regular exercise program is Class I or IIa recommendation. Recently, a randomized prospective trial (Heart Failure-A Controlled Trial Investigating Outcome of Exercise Training, HF-ACTION) demonstrated that aerobic exercise modestly reduces the risk for clinical events in HF patients. However, cardiac rehabilitation program should be individualized and more research for heart failure with preserved ejection fraction (HFPEF) needed because approximately on half of patients with HF have preserved ejection fraction. There, this article provides the effects of regular exercise on clinical outcomes of HF patients and a brief practical guide for prescribing exercise in these patients.
