Abstract
Currently, the number of patients with heart failure (HF) and cognitive impairment (CI) is growing. In this regard, it is necessary to screen for CI in patients with HF. The Mini-Сog test is one of the screening tests, but more research is needed to examine the feasibility of using it on a cohort of cardiac patients.
Aim of the study. The aim of the study is to assess the sensitivity and specificity of the Mini-Сog test in identifying patients with CI among patients aged 65 and over with HF.
Materials and methods. From March 2021 to March 2023, 149 people aged 65 and older with chronic heart failure
(CHF) were selected from a separate structural unit of the Russian Gerontology Research and Clinical Center of the Pirogov Russian National Research Medical University. Cognitive status was assessed using the Montreal Cognitive Assessment Scale and the Mini-Mental State Examination. All patients underwent the Mini-cog testing. Statistical analysis was performed using ROC analysis.
Results and conclusions. The prevalence of cognitive impairment among patients with CHF aged 65 or older, according to our study, is 67.8%. A cutoff value of 2 points or less points on the Mini-Cog test (AUC 0.856; CI 95% 0.7750.936, p < 0.001) indicates the presence of severe cognitive impairment with a sensitivity of 61.5% and a specificity of 92.1%. A score of 3 points or lower (AUC 0.828; CI 95% 0.762-0.894, p < 0.001) indicates mild cognitive impairment (MCI) with a sensitivity of 55.4% and a specificity of 93.7%, and dementia with a sensitivity of 80.8% and a specificity of 69.1%.
