Role of diabetes in heart rhythm disorders

Area of Science:

• Cardiology
• Endocrinology
• Clinical Medicine

Background:

• Diabetes mellitus (DM) incidence is rapidly increasing globally.
• DM is a primary driver of cardiovascular diseases (CVDs), exacerbating atherosclerosis.
• DM independently elevates risks for macrovascular and microvascular complications, including myocardial infarction, stroke, and retinopathy.

Purpose of the Study:

• To provide a concise overview of the association between DM and cardiac rhythm disorders.
• To elucidate the underlying pathophysiological mechanisms linking DM to arrhythmias.
• To highlight DM as a critical risk factor for cardiovascular morbidity and mortality.

Main Methods:

• Literature review of studies on diabetes and cardiac arrhythmias.
• Analysis of pathophysiological mechanisms connecting DM to atrial fibrillation (AF) and ventricular arrhythmias (VA).
• Synthesis of current understanding on DM's impact on cardiovascular health and rhythm disturbances.

Main Results:

• DM is strongly associated with increased prevalence of atrial fibrillation (AF) and ventricular arrhythmias (VA).
• Aggravated atherosclerosis and macro/microangiopathy in DM patients contribute to cardiac complications.
• DM significantly increases cardiovascular morbidity and mortality, often linked to rhythm disorders.

Conclusions:

• Diabetes mellitus poses a substantial threat to cardiovascular health, markedly increasing the risk of arrhythmias.
• Understanding the pathophysiological links between DM and disorders like AF and VA is crucial for patient management.
• Effective DM management is essential to mitigate associated cardiovascular risks and improve patient outcomes.
