Diabetes and Atrial Fibrillation: Insight From Basic to Translational Science Into the Mechanisms and Management

Area of Science:

• Cardiology
• Endocrinology
• Translational Science

Background:

• Atrial fibrillation (AF) remains a major cause of mortality and morbidity, including heart failure and stroke.
• Diabetes mellitus (DM) is an independent risk factor for AF, exacerbating adverse outcomes.
• The interplay between DM and AF involves complex pathophysiology, including atrial cardiomyopathy.

Purpose of the Study:

• To review the intricate mechanisms underlying AF in patients with DM.
• To discuss current and emerging management strategies for AF in the context of DM.
• To bridge insights from basic science to translational applications.

Main Methods:

• Review of current literature on the pathophysiology of AF in DM.
• Analysis of basic science findings related to atrial remodeling and dysfunction in DM.
• Examination of clinical studies on AF management in diabetic patients.

Main Results:

• DM contributes to AF through structural changes (atrial cardiomyopathy), fibrosis, and impaired cardiac function.
• Key factors include ion channel abnormalities, renin-angiotensin-aldosterone system dysregulation, and autonomic dysfunction.
• Understanding these mechanisms is crucial for effective AF management in DM.

Conclusions:

• The relationship between DM and AF is multifactorial, involving significant atrial remodeling.
• Targeting DM-related pathways offers potential for novel AF therapies.
• Integrated management strategies are essential for improving outcomes in patients with both conditions.
