Inflammatory and Infectious Processes Serve as Links between Atrial Fibrillation and Alzheimer's Disease

Area of Science:

• Cardiology
• Neurology
• Pathophysiology

Background:

• Atrial fibrillation (AF) is a common arrhythmia linked to stroke and cognitive decline.
• Alzheimer's disease (AD) is the leading cause of dementia with complex, not fully understood, pathogenesis.
• Inflammation and infection are increasingly implicated in both AD and AF, suggesting a potential common etiology.

Purpose of the Study:

• To elucidate the shared pathophysiological pathways between atrial fibrillation and Alzheimer's disease.
• To identify overlapping predictive biomarkers for both conditions.
• To discuss emerging pharmacological strategies for joint treatment approaches.

Main Methods:

• Review of current literature on the pathophysiology of AF and AD.
• Analysis of shared inflammatory and infectious mechanisms.
• Exploration of potential overlapping biomarkers and therapeutic targets.

Main Results:

• Identification of key shared pathways, including inflammation, linking AF and cognitive decline.
• Highlighting of potential predictive biomarkers common to both conditions.
• Discussion of novel therapeutic strategies targeting these shared pathways.

Conclusions:

• A common link exists between atrial fibrillation and Alzheimer's disease, primarily driven by inflammatory processes.
• Further research into shared biomarkers and joint pharmacological approaches is warranted for effective treatment of both conditions.
