Coronary heart disease and atrial fibrillation: a vicious cycle

Area of Science:

• Cardiology
• Internal Medicine

Background:

• Coronary heart disease (CHD) and atrial fibrillation (AF) are increasingly comorbid conditions.
• Shared risk factors and bidirectional disease mechanisms contribute to their strong correlation.

Purpose of the Study:

• To review the complex interplay between CHD and AF.
• To explore strategies for breaking the vicious cycle between these two conditions.

Main Methods:

• Literature review of studies investigating the relationship between CHD and AF.
• Analysis of mechanisms by which CHD affects AF and vice versa.
• Examination of current treatment guidelines and emerging therapeutic strategies.

Main Results:

• CHD can promote AF progression through reentry, ectopic activity, and neural remodeling.
• AF exacerbates CHD via atherosclerosis, oxygen supply-demand mismatch, and thrombosis.
• A vicious cycle exists where CHD and AF aggravate each other.

Conclusions:

• Understanding the bidirectional relationship is crucial for managing patients with comorbid CHD and AF.
• Antithrombotic therapy and rhythm control are key current treatments.
• Developing strategies to interrupt the CHD-AF cycle is fundamental for optimizing patient care and outcomes.
