The Long- and Short-Term Impact of Elevated Body Mass Index on the Risk of New Atrial Fibrillation

Key Points

• Investigate how elevated body mass index influences the risk of developing new atrial fibrillation over both short and long durations.
• Assessment of participants' body mass index and atrial fibrillation incidence
• Longitudinal follow-up to evaluate both short- and long-term effects
• Statistical analyses of risk factors associated with atrial fibrillation
• Individuals with elevated body mass index showed a 20% increased risk of developing atrial fibrillation (RR 1.2, 95% CI 1.1-1.4, p=0.02)
• Short-term exposure (less than one year) shows a 15% increase in risk (HR 1.15, 95% CI 1.05-1.25, p=0.03)
• Long-term effects indicate a stronger correlation, with a 30% higher risk over five years (OR 1.3, 95% CI 1.2-1.5, p=0.001)
