Atrial Fibrillation Ablation Outcomes Vary by Age and Frailty in Older Adults

Strategic Insights -

According to a recent study published in the Journal of Cardiovascular Electrophysiology, researchers have found that the outcomes of catheter ablation for atrial fibrillation (AF) vary significantly by age and frailty in older adults. The study analyzed data from the 2016-2021 National Inpatient Sample database, identifying patients undergoing catheter ablation for AF. The researchers found that patients over 80 years had higher odds of cardiac rhythm restoration and pacemaker implantation but lower risks of cardiogenic shock, mechanical circulatory support, heart failure, myocardial infarction, and major adverse cardiac and cerebrovascular events (MACCE).

Key Takeaways:

  • A total of 292,395 patients underwent catheter ablation for AF between 2016 and 2021, with 79.2% of patients aged 35-65 years, 15.7% aged 66-79 years, and 5.1% aged 80 years.
  • The proportion of patients aged 80 years increased from 11% in 2016 to 21.1% in 2021.
  • Females comprised a higher proportion of the oldest age group (51.4%), but no sex differences were observed across frailty levels.
  • In-hospital mortality was highest in the high frailty group.
  • Higher frailty was associated with an increased risk of in-hospital mortality, complications, and MACCE.
  • Catheter ablation is increasingly performed in older patients, emphasizing the need for strategies to mitigate risks in this population.

Statistics:

  • 292,395 patients underwent catheter ablation for AF between 2016 and 2021.
  • 79.2% of patients were aged 35-65 years.
  • 15.7% of patients were aged 66-79 years.
  • 5.1% of patients were aged 80 years.
  • The proportion of patients aged 80 years increased from 11% in 2016 to 21.1% in 2021.
  • Females comprised 51.4% of the oldest age group.
  • In-hospital mortality was 1.3% in the high frailty group.
