Pathophysiology of atrial fibrillation and chronic kidney disease

Area of Science:

• Cardiology and Nephrology
• Clinical Medicine

Background:

• Atrial fibrillation (AF) and chronic kidney disease (CKD) are increasingly prevalent, often co-occurring.
• Shared risk factors and complex interlinking mechanisms contribute to the association between AF and CKD.

Purpose of the Study:

• To review the pathophysiology and clinical implications of concurrent AF and CKD.
• To examine the risks of thrombo-embolic and bleeding events in patients with both conditions.
• To discuss the evidence and guideline uncertainties regarding oral anticoagulation (OAC) for stroke prevention in AF and CKD.

Main Methods:

• Literature review of studies investigating the relationship between AF and CKD.
• Analysis of pathophysiological mechanisms linking the two conditions.
• Evaluation of clinical outcomes, including stroke and bleeding risks.
• Assessment of current evidence on OAC use in this patient population.

Main Results:

• Concurrent AF and CKD present complex management challenges.
• Patients with both conditions face elevated risks of stroke and bleeding complications.
• There is significant uncertainty and lack of consensus in international guidelines regarding OAC use.

Conclusions:

• Understanding the interplay between AF and CKD is crucial for effective patient management.
• Further research is needed to clarify optimal OAC strategies for stroke prevention in patients with co-existing AF and CKD.
