BackgroundThe usefulness of echocardiographic characteristics for dementia prediction in patients with heart failure decompensation (HFD) is not determined. Therefore, we sought to investigate the echocardiographic features of patients with HFD and screening diagnosis of dementia (SDD).Methods139 patients aged over 65 years were hospitalized with the diagnosis of HFD. Clinical characteristics and echocardiographic characteristics were recorded during hospitalization. SDD was defined based on the result of ALFI- MMSE of <17 points.ResultsPatients with SDD were older (p=0.013), had thicker IVSd (p=0.021), thicker PWd (p=0.005) and had a higher RWT (0.40 vs 0.35, p=0.004) than patients without SDD, without differences in LVMI (p=0.13). There was no correlation between RWT and LVMI (r=-0.01, p=0.88). In the multivariate analysis, an older age (β=-0.116, 95% CI -0.224 - -0.008, p=0.035, per year) and a higher RWT (β=-0.069, 95% CI -0.137 - -0.002, p=0.045, per 0.01) influenced a lower ALFI-MMSE. For a prediction of SDD, the RWT reached the area under a ROC curve of 0.67 (95% CI 0.56-0.77, p=0.004 with sensitivity of 60% and specificity of 70% for RWT of ≥0.375).ConclusionsApart from age, RWT reflecting left ventricular geometry changes but not hypertrophy was independently but moderately associated with SDD in patients following HFD (Tab. 4, Fig. 1, Ref. 35).
