Thirty-day readmissions after atrial fibrillation catheter ablation in patients with heart failure.
Abstract
Randomized clinical trial data have demonstrated catheter ablation (CA) as a viable treatment modality for atrial fibrillation (AF). Patients with heart failure (HF) undergoing AF CA appear to derive improvements in quality of life and mortality compared to those treated with medical therapy (MT). Contemporary national data on 30-day readmissions after CA compared to MT among patients with HF are lacking. From the 2016 Nationwide Readmissions Databases, 749 776 (weighted national estimate: 1 421 673) AF HF patients were identified of which 2204 (0.3%) underwent CA and 747 572 (99.7%) received MT. Propensity matching balanced baseline clinical characteristics. Thirty-day readmission rates, causes, predictors, and costs of 30-day readmission were compared. Among both the unmatched and matched cohorts, 30-day readmissions were lower for patients treated with CA compared to MT (16.8% vs 20.1%, P < .001 and 16.8% vs 18.8%, P = .020). CA was associated with reduced risk of readmission compared to MT (odds ratio 0.86, 95% confidence interval [CI]: 0.77-0.97). HF exacerbation and arrhythmias were the most common cause for 30-day readmission after CA. CA costs were higher during index hospitalization but similar to MT during readmission...Continue Reading

Atrial Filbrillation
Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.
Arrhythmia
Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
Atrial Fibrillation
Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.
