The rate of catheter ablation for hospitalized patients with atrial fibrillation increased significantly from 0.06% in 1990 to 0.79% in 2005, representing a 15% annual increase (95% CI 13-16%).
Observational (n=269,471)
Yes
The use of catheter ablation for atrial fibrillation in the United States increased significantly between 1990 and 2005, with ablated patients generally being younger and having fewer comorbidities.
Effect estimate: 15% increase per year (95% CI 13-16)
Absolute Event Rate: 0.79% vs 0.06%
p-value: p=<0.001
BACKGROUND: There are few data on the use of catheter ablation for atrial fibrillation (AF) in the United States. We analyzed data from the National Hospital Discharge Survey (NHDS) to examine trends in the rate of catheter ablation for hospitalized patients with AF over a 15-year period. OBJECTIVE: To examine rates of catheter ablation in patients with AF over time. DESIGN: All adult patients in the NHDS with an International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) code for AF from the years 1990 to 2005 were identified and assessed for the presence of a cardiac catheter ablation procedure code. Clinical characteristics associated with ablation were identified and multivariable logistic regression used to determine trends in the rate of ablation therapy over time. RESULTS: We identified 269,471 adults with AF. The rate of catheter ablation in AF patients increased from 0.06% in 1990 to 0.79% in 2005 (P 75 years, diabetes mellitus, or stroke/transient ischemic attack (37% versus 16%; P or =80 years (0.0% in 1990 and 0.26% in 2005; P < 0.001 for trend). CONCLUSIONS: The rate of catheter ablation in patients with AF is increasing significantly over time, even in the oldest patients. Medicine.
Kneeland et al. (Tue,) conducted a observational in Atrial fibrillation (n=269,471). Catheter ablation vs. No ablation was evaluated on Rate of catheter ablation over time (15% increase per year, 95% CI 13-16, p=<0.001). The rate of catheter ablation for hospitalized patients with atrial fibrillation increased significantly from 0.06% in 1990 to 0.79% in 2005, representing a 15% annual increase (95% CI 13-16%).
