hfaction_cpx12: A dataset from the HF-ACTION trial
In WA: While-Alive Loss Rate for Recurrent Event in the Presence of Death

The Heart Failure: A Controlled Trial Investigating Outcomes of Exercise Training (HF-ACTION) study was conducted between 2003–2007 to investigate whether adding exercise training to the usual care of heart failure patients improves their cardiovascular outcomes (O'Conner et al., 2009). This dataset is for a high-risk subgroup consisting of 741 nonischemic patients with baseline cardiopulmonary test duration less than or equal to 12 minutes and analyze recurrent hospitalizations as well as overall survival.
