Insights

Men, younger patients, and those with higher education and employment are more likely to receive atrial fibrillation (AF) ablation. Women, older individuals, and those with lower socioeconomic status face disparities in AF ablation access.

Area of Science:

  • Cardiology
  • Public Health
  • Health Services Research

Background:

  • Atrial fibrillation (AF) is a prevalent arrhythmia impacting quality of life and increasing stroke risk.
  • Catheter ablation offers effective treatment for AF but equitable access remains a concern.
  • Identifying demographic disparities in AF ablation is crucial for improving patient outcomes.

Purpose of the Study:

  • To investigate demographic factors influencing the likelihood of receiving atrial fibrillation ablation.
  • To identify patient groups with reduced access to AF ablation procedures.

Main Methods:

  • Analysis of nationwide Danish registry data from 2010-2018, including 176,248 patients with newly diagnosed AF.
  • Multivariable Cox proportional hazard analysis to assess associations between demographics and ablation likelihood.
  • Aalen-Johansen estimator for cumulative incidence calculation.

Main Results:

  • Men (7%) were more likely to undergo ablation than women (3%).
  • Ablation rates were highest in patients aged 25-64 and decreased significantly with age, with only 0.7% of those 80+ receiving it.
  • Higher education and full-time employment correlated with increased likelihood of ablation, while retired patients had the lowest rates (3%).

Conclusions:

  • Significant disparities exist in AF ablation access based on gender, age, education, and employment status in Denmark.
  • Women, older patients, those with lower education, and individuals on social benefits are less likely to receive this treatment.
  • Addressing these socioeconomic and demographic disparities is essential for equitable AF management.
