Analysis of factors associated with cognitive impairment in elderly patients hospitalized with chronic heart failure.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Objective: This study systematically investigates the prevalence of cognitive impairment (CI) and its associated factors among older inpatients with chronic heart failure (CHF), aiming to inform early clinical screening and targeted interventions. Methods: A cross-sectional study consecutively enrolled 220 CHF inpatients aged ≥ 60 years from the Department of Cardiology and General Medicine at the Fourth Affiliated Hospital of Anhui Medical University between October 2024 and November 2025. Cognitive function was assessed using the Chinese version of the Mini-Mental State Examination (MMSE). Demographic, clinical, and laboratory data-including NT-proBNP, lipid profiles, and left ventricular ejection fraction (LVEF) -were collected. Intergroup comparisons were performed, and variables significant in univariate analysis ( Conclusion: Cognitive impairment is highly prevalent among older inpatients with CHF and is influenced by advanced age, elevated NT-proBNP, sleep disorders, diabetes, lower education, and reduced LVEF. These findings highlight the high prevalence and associated factors of cognitive impairment in elderly patients with chronic heart failure, which may enhance clinical awareness of cognitive status in this population.
