Cognitive impairment in heart failure patients

Area of Science:

• Neurology
• Cardiology
• Psychology

Background:

• Heart failure (HF) is associated with cognitive impairment, impacting patients' ability to manage their health.
• Brain imaging reveals structural and functional changes in grey and white matter affecting cognitive domains in HF.
• Existing cognitive assessment tools lack consensus for optimal use in the HF population.

Purpose of the Study:

• To review current knowledge on cognitive impairment in heart failure.
• To identify etiological mechanisms and risk factors for cognitive deficits in HF.
• To highlight areas for future research in HF-related cognitive dysfunction.

Main Methods:

• Systematic review of existing literature on cognitive function in heart failure.
• Analysis of neuroimaging findings related to cognitive changes in HF.
• Evaluation of etiological factors including cerebral blood flow, cardiac output, and blood pressure.

Main Results:

• Cognitive damage in HF affects multiple domains, hindering self-care and treatment adherence.
• Cerebral blood flow reduction, decreased cardiac output, and altered cerebrovascular reactivity contribute to cognitive deficits.
• Cardiac, laboratory, demographic, and clinical factors are linked to cognitive impairment risk in HF.

Conclusions:

• Cognitive impairment is a significant complication of heart failure with diverse impacts.
• Understanding the interplay of cardiovascular and neurological factors is crucial for managing HF cognitive dysfunction.
• Further research is needed to refine assessment tools and identify at-risk HF populations.
