Although a single cutoff of 0.98\u2009m\/s has been proposed based on post\u2010discharge prognosis, the continuous relationship between gait speed and outcomes suggests the possible presence of multiple cutoffs. Identifying these thresholds may help establish stepwise, attainable goals for a broad range of older HF patients. This study aimed to determine whether additional prognostic gait speed cutoffs exist at discharge in older HF patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We conducted a secondary analysis of the J\u2010Proof HF, comprising 7326 hospitalized patients aged \u2265\u200965\u2009years with confirmed HF. The cohort was randomly divided into a derivation (60%) and a validation (40%) cohort. The primary outcome was a composite of all\u2010cause death or HF readmission within 1\u2009year. Gait speed cutoffs were identified in the derivation cohort using survival classification and regression tree (CART) analysis and validated in the validation cohort.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Three prognostic cutoffs were identified (&lt;\u20090.39, &lt;\u20090.69, and &lt;\u20091.00\u2009m\/s), defining four gait speed categories.
