Predictors for Progression of Atrial Fibrillation in Patients Awaiting Atrial Fibrillation Ablation

2017 HRS/EHRA/ECAS/APHRS/SOLAECE expert consensus statement on catheter and surgical ablation of atrial fibrillation

“…Similar results were reported in another recent study that examined AF progression while waiting for an AF ablation procedure. 19 Among 564 patients with PAF, 11% progressed to persistent AF during a 10-month follow-up period. In this study, heart failure (HF) and a left atrial (LA) diameter >45 mm were predictive of progression.…”

Clinical scores for outcomes of rhythm control or arrhythmia progression in patients with atrial fibrillation: a systematic review

“…In the original study, nearly 50% of patients with a HATCH score of >5 progressed to persistent AF, but only 6% of those with a score of 0 experienced AF progression. A subsequent study of AF patients who were awaiting CA found the HATCH score to be a poor predictor of AF progression [ 19 ]. Similar observations were seen in the Belgrade AF study, which showed that the HATCH score had only very modest predictive value (c statistic, 0.6) for the arrhythmia progression in a cohort of lone AF patients over a 12-year follow-up period [ 20 ].…”

Why is chronic obstructive pulmonary disease linked to atrial fibrillation? A systematic overview of the underlying mechanisms

“…In addition to the above-mentioned scores, a left atrial diameter of >45 mm and heart failure are among the strongest independent predictors of AFib [6].…”
