Impact of Low Body Mass Index on Cardiac Tamponade During Catheter Ablation for Atrial Fibrillation

In this analysis of a large nationwide database of patients with AF who underwent ablation, being underweight was independently associated with an increased risk of cardiac tamponade during AF ablation.
Study context
- Population
- Patients undergoing catheter ablation for atrial fibrillation (AF), Japan, April 2016–March 2018
- Participants
- 59,789 hospitalizations
- Exposure
- Underweight vs normal weight
- Outcome
- Cardiac tamponade during AF ablation
Methodological detailsJapanese nationwide claims database, mixed-effects multivariable Poisson regression

As reported in the abstract
- Cardiac tamponade overall (647 patients)
- 1.1%
Observational data: associations, not effects.
Further findings
Other risk factors for cardiac tamponade
- Increased risk with age ≥75 years, female sex, history of HF, hypertension, DM and dialysis
