Zusammenfassung: | Background
Obesity and diabetes are risk factors for atrial fibrillation (AF) incidence and recurrence after catheter ablation. However, their impact on post‐ablation complications in real‐world practice is unknown.
Objectives
We examine annual trends in AF ablations and procedural outcomes in obese and diabetic patients in the US and whether obesity and diabetes are independently associated with adverse outcomes.
Methods
Using the Nationwide Inpatient Sample (2005–2013), we identified obese and diabetic patients admitted for AF ablation. Common complications were identified using ICD‐9‐CM codes. The primary outcome included the composite of any in‐hospital complication or death. Annual trends of the primary outcome, length‐of‐stay (LOS) and total‐inflation adjusted hospital charges were examined. Multivariate analyses studied the association of obesity and diabetes with outcomes.
Results
An estimated 106 462 AF ablations were performed in the US from 2005 to 2013. Annual trends revealed a gradual increase in ablations performed in obese and diabetic patients and in complication rates. The overall rate of the primary outcome in obese was 11.7% versus 8.2% in non‐obese and 10.7% in diabetic versus 8.2% in non‐diabetic patients (p |
