Modifiable Risk Factors in Atrial Fibrillation: Clinical Implications and Pathophysiological Insights

Area of Science:

• Cardiology
• Electrophysiology
• Preventive Medicine

Background:

• Atrial fibrillation (AF) is a prevalent arrhythmia, with rising incidence linked to modifiable lifestyle and clinical factors.
• Understanding the impact of obesity, hypertension, diabetes, OSA, alcohol, and fitness on AF is crucial for prevention and treatment.

Purpose of the Study:

• To review literature on six key modifiable risk factors for AF.
• To synthesize evidence on pathophysiological effects and intervention impacts on AF.

Main Methods:

• Narrative literature review.
• Assessment of six modifiable AF risk factors.
• Synthesis of pathophysiological effects and intervention outcomes.

Main Results:

• Increased BMI, hypertension, diabetes, OSA, alcohol intake, and extreme cardiorespiratory fitness elevate AF risk.
• Weight loss, CPAP, and moderate exercise improve AF outcomes.
• Shared mechanisms include fibrosis, inflammation, and autonomic imbalance.

Conclusions:

• Integrating risk-factor modification into AF management enhances procedural efficacy.
• Addresses fundamental AF disease mechanisms for improved prevention and therapy.
