Abstract:
BACKGROUND AND OBJECTIVES: This examined the association of cognitive function with self-care and major adverse cardiac events (MACE) among heart failure (HF) patients. SUBJECTS AND METHODS: In this prospective study, 86 outpatients with HF completed face-to-face interviews including neuropsychological testing to evaluate cognitive function and the use of the Self-Care of Heart Failure Index to measure self-care. Functional status was assessed with the New York Heart Association (NYHA) classification. Follow-up data on MACE were obtained at 24 months after enrollment. RESULTS: Compared with the Korean norm values, more than half of the HF patients had cognitive deficits in global function (33.0%), immediate recall (65.1%), delayed recall memory (65.1%), and executive function (60.5%). Patients with symptomatic HF (> or =NYHA class II) had the higher risk for substantially poor cognitive function in all areas of cognitive function than asymptomatic HF patients (NYHA class I, p<0.05). Most patients demonstrated poor self-care adequacy in maintenance (84.9%), management of symptoms (100%), and confidence (86.0%). After adjustment for age and gender, memory function was significantly associated with self-care confidence (odds ratio 1.41, 95% confidence interval 1.03-1.92, p=0.033). No relationship was found between cognition and self-care maintenance. There were 19 MACE's during the 24-month follow-up. Patients without MACE had a significantly higher global cognitive function (p=0.024), while no cognitive domains were significant predictors of MACE when adjusted for age and gender. CONCLUSION: HF patients with memory loss have poorer self-care confidence. Studies are warranted to examine the functional implication of cognitive deficits and adverse outcomes in a larger sample.
