Clinical Profile and Prognosis of Dementia in Patients With Acute Decompensated Heart Failure　― From the CURE-HF Registry

Background: Acute decompensated heart failure (ADHF) has a poor prognosis and common comorbidities may be contributory. However, evidence for the association between dementia and clinical outcomes in patients with is sparse and it requires further investigation into risk reduction.Methods and Results: We assessed the clinical profiles and outcomes of 1,026 patients (mean age 77.8 years, 43.2% female) with ADHF enrolled in the CURE-HF registry to evaluate the relationship between investigator-reported dementia status and clinical outcomes (all-cause death, cardiovascular (CV) death, non-CV death, and HF hospitalization) over a median follow-up of 2.7 years. In total, dementia was present in 118 (11.5%) patients, who experienced more drug interruptions and HF admissions due to infection than those without dementia (23.8% vs. 13.1%, P
