Key result
Decreased eGFR and elevated LAVI independently predict long-term atrial tachyarrhythmia recurrence after AF ablation.
Why the study?
The effect of renal function on the efficiency and long-term prognosis of catheter ablation for atrial fibrillation was not well understood.
Does decreased eGFR predict long-term recurrence of atrial tachyarrhythmia in patients undergoing first-time catheter ablation for AF?
Cohort (n=306)
No

Effect estimate: AUC 0.725 (95% CI 0.67-0.77)
p-value: p=<0.001
Decreased eGFR and elevated LAVI are independent predictors of long-term recurrence of atrial tachyarrhythmia after first-time catheter ablation for AF.
No takes yet. Share an insight, caveat, or question.
Impaired renal function may worsen post-ablation AF outcomes; hypothesis-generating and requires prospective validation before guiding practice.
Zheng et al. (2021) conducted a cohort in Atrial fibrillation (n=306). Decreased estimated glomerular filtration rate (eGFR) vs. Higher eGFR was evaluated on Long-term recurrence of atrial tachyarrhythmia (AUC 0.725, 95% CI 0.67-0.77, p=<0.001). Decreased estimated glomerular filtration rate (AUC 0.725) and elevated left atrial volume index independently predicted long-term recurrence of atrial tachyarrhythmia after catheter ablation for atrial fibrillation.
