The "Heart Failure: A Controlled Trial Investigating Outcomes of Exercise Training" (HF-ACTION) study was conducted in 2003-2007. The aim was to investigate whether adding exercise training to the usual care of heart failure patients could improve cardiovascular outcomes (O'Conner et al., 2009). The trial recruited 2331 participants across the United States, Canada, and France, and used the composite of all-cause death and all-cause hospitalization as the primary endpoint. This dataset come from a high-risk subgroup consisting of 741 nonischemic patients with baseline cardiopulmonary test duration less than or equal to 12 minutes (Mao, 2022).
