Aim: To test the relationship between cognitive function and self-care in patients with heart failure after adjusting for the contribution of age, education, functional status, myocardial stress, sleep and depression. Further, the relationship between cognitive function and self-care was explored with depression and sleep as moderators.
Background: Self-care can significantly impact functional capacity, well-being, morbidity, and prognosis in patients with heart failure (HF). However, self-care requires the cognitive ability to learn, perceive, interpret and respond. The influence of demographics and clinical symptoms on the relationship between cognition and self-care needs to be further understood.
Design: Descriptive, cross-sectional study.
Methods: The study included 142 patients with chronic HF (68% male, median age 72 years, 61% in NYHA II). Self-care was measured with the European Heart Failure Self-Care Behavior Scale. Cognitive function was evaluated with neuropsychological tests measuring global cognitive dysfunction, psychomotor speed, executive function, visual-spatial perception/construct, spatial performance, semantic and episodic memory.
Findings: Psychomotor function (speed and attention) measured with the Trail Making A was the only dimension of cognitive function significantly associated with self-care. Neither depressive symptoms, nor sleep disturbances moderated the relation between cognitive function and selfcare.
Conclusion: Deficits in psychomotor speed have implications for how patients should be educated and supported to perform self-care. A decrease in sustained attention and ability to carry out more than one task at a same time could lead to difficulties in self-care. Screening for psychomotor speed is therefore advocated for patients with HF.
