Characteristics and influencing factors of cognitive function in hospitalized patients with the chronic heart failure

Abstract:

Objective：To investigate the cognitive function and influential factors of hospitalized patients with the chronic heart failure （CHF）. Methods：A total of 104 CHF patients were conveniently drawn from patients in 5 hospitals and were evaluated by Montreal cognitive assessment scale（MoCA） Beijing Edition. Results：The prevalence of the cognitive impairment in 104 CHF patients in this study was 71.2%. The abnormal rates in each field ranking from high to low were delayed recall（92.3%），visual space and executive function（85.6%），language（76.0%），abstract（57.7%），attention（27.9%），naming （2.9%） and orientation（0.0%）. The multivariate lin－er regression analysis indicated age（B=-0.024，P=0.027） and education years（B=0.117，P=0.000） into the equation of visual space and executive function，sleep score（B=-0.036，P=0.037）into the equation of delayed recall，education years（B=0.088，P=0.000） and sleep score（B=-0.038，P=0.022） into the equation of attention，age（B=-0.015，P=0.042） and education years（B=0.047，P=0.019） in－to the equation of abstract，education years（B=0.074，P=0.001） into the equation of language，age（B=-0.067，P=0.029），education years（B=0.273，P=0.001） and NYHA grades（B=-0.915，P=0.017） into the equation of MoCA score. Conclusion：The prevalence of cognitive impairment in CHF patients was relatively high，especially the delayed recall impairment. Age，sleep disorders，and higher NYHA grades may be independent risk factors for cognitive impairment in patients with chronic heart failure，and higher education was a protective factor for cognitive impairment in CHF patients.
