We divided patients into three groups according to the severity of frailty using the KCL and compared clinical outcomes after discharge. The primary endpoint was all-cause death, and the secondary outcomes were cardiovascular death, heart failure (HF) rehospitalization, and the composite event of cardiovascular death and HF rehospitalization. Of 936 patients (median age, 81 years; 48.9% women) who could be assessed for frailty, we identified frailty in 501 patients (53.5%), prefrailty in 290 patients (31.0%), and non-frailty in 145 patients (15.5%). Compared with prefrail and non-frail patients, frail patients were older (83 vs. 79 and 72 years, P &amp;lt; 0.001), were more likely to be women (53.9% vs. 43.1% and 43.4%, P = 0.005), and were more likely to have a history of previous HF hospitalization (35.4% vs. 25.3% and 19.6%, P &amp;lt; 0.001) and multimorbidity (90.8% vs. 81.0% and 73.8%, P &amp;lt; 0.001). Frail patients had a lower rate of discharge to home (79.7% vs. 94.8% and 96.5%, P &amp;lt; 0.001). During the 2 year follow-up period, frail patients had a higher incidence rate of all-cause death, cardiovascular death, and HF rehospitalization (log-rank P &amp;lt; 0.001, P &amp;lt; 0.001, and P = 0.003, respectively). After adjusting for other prognostic factors, multivariate analysis showed that frailty was associated with all-cause death [adjusted hazard ratio (HR): 2.917, 95% confidence interval (CI): 1.326\u20136.417, P = 0.008] and cardiovascular death (adjusted HR: 7.026, 95% CI: 1.700\u201329.030, P = 0.007). Among all domains of the KCL, the cognitive function domain was associated with a higher risk of all-cause death (P = 0.004) and cardiovascular death (P &amp;lt; 0.001). The depression domain remained associated with a higher risk of HF rehospitalization (P = 0.045). The risk for all-cause death increased with an increase in total KCL score (adjusted HR: 1.819, 95% CI: 1.300\u20132.547, P &amp;lt; 0.001).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The KCL is a useful tool for risk stratification of adverse outcomes in patients with AHF.
