The Heart’s Rhythm and the Brain’s Strain: Unravelling the Link Between Atrial Fibrillation and Heart Failure
A comprehensive review in *Heart* synthesizes the complex interplay between atrial fibrillation (AF) and heart failure with preserved ejection fraction (HFpEF), a condition with significant neurological and cognitive implications. The article details how AF complicates the diagnosis and management of HFpEF, a syndrome characterized by elevated cardiac filling pressures and exercise intolerance often linked to underlying cardiometabolic disturbances. The review explores the impact of AF on disease detection, symptom burden, and patient prognosis, while also evaluating current pharmacological and interventional therapies aimed at mitigating AF risk to improve patient outcomes in feeling, function, and survival. This analysis is crucial for understanding the systemic and cerebrovascular consequences of these intertwined cardiovascular disorders.
Study Significance: For neurologists and neuroscientists, this review underscores the critical need to consider cardiovascular comorbidities like AF and HFpEF when evaluating cognitive impairment and stroke risk. The systemic hypoperfusion and neuroinflammation associated with these conditions can accelerate neurodegeneration and worsen outcomes in diseases like vascular dementia. Integrating cardiovascular management into neurological care protocols could be a strategic imperative for improving long-term brain health and patient function.
