This subproject is one of many research subprojects utilizing theresources provided by a Center grant funded by NIH/NCRR. The subproject andinvestigator (PI) may have received primary funding from another NIH source,and thus could be represented in other CRISP entries. The institution listed isfor the Center, which is not necessarily the institution for the investigator.Heart Failure and A Controlled Trial Investigating Outcomes of Exercise TraiNing (HF-ACTION) is a multicenter, international, randomized trial that addresses the primary hypothesis that patients with left ventricular (LV) systolic dysfunction and New York Heart Association (NYHA) class II-IV symptoms who are given exercise training in addition to standard care will have a > 20% lower rate of death and hospitalization over two years than patients who receive usual care alone. Important secondary endpoints include exercise testing parameters, economics, quality of life, and depression. Over three years, regional centers in the United States and Canada and their satellite centers will recruit 3,000 consenting patients with heart failure (HF), LV ejection fraction (EF) 35%, and NYHA class II-IV. Once identified and screened, these patients will be randomized in a 1:1 fashion to receive usual care or usual care plus exercise training. Patients in the intervention arm will undergo 36 supervised exercise training sessions before initiating a home exercise training regimen that will be supplemented with occasional supervised review training sessions. All patients will perform gas exchange exercise tests at baseline, 3 months, 12 months, and 24 months of follow-up. All randomized patients will receive follow-up clinic and telephone calls at pre-specified times. Registries of clinical information will be maintained on eligible patients who decline trial entry. The results of the HF-ACTION trial will have a significant impact on the health and quality of life of millions of patients who now suffer from HF.
