OBJECTIVE: To explore the cognitive function status and potential influence factors on cognitive function in hospitalized patients with chronic heart failure. METHODS: Using a cross-sectional research design, CHF patients (n = 267, mean age (63.8 ± 9.4) years) were recruited from two care units-Heart Failure Care Unit and Intensive Care Unit of our hospital. Cognitive function status was evaluated by the Montreal Cognitive Assessment (MoCA) screen test. RESULTS: Based on the MoCA score, 37.8% (101/267) patients suffered from cognitive impairment (score<26), especially on the three specific cognitive functions-memory, langue and executive capability. Multifactorial analysis showed that after controlling for other factors, there was a downward trend on cognitive function with aging (OR = 1.09, 95%CI:1.05-1.14) while higher left ventricular ejection fraction (LVEF) was related to better cognitive function (OR = 0.97, 95%CI:0.95-0.99); patients who took medicine regularly also had better cognitive function (OR = 3.71, 95%CI:1.40-10.91); cognitive function was better in patients with high level of social support compared those with low social support (OR = 0.92, 95%CI:0.88-0.96). CONCLUSIONS: Incidence of cognitive impairment is high in hospitalized patients with chronic heart failure. Age, LVEF, whether taking medication regularly and social support are factors related to cognitive function in CHF patients.
