- W2981692034 abstract "Abstract Catheter ablation for atrial fibrillation (AF) is a validated therapy for patients with symptomatic AF to prevent recurrences. The CASTLE AF trial indicated that ablation for AF in patients with heart failure was associated with a lower rate of death from any cause or hospitalization for worsening heart failure than was medical therapy. However, the benefit of AF ablation was not significant in older patients (>65 yo). The purpose of our study was to compare the incidence of these events in patients after AF catheter ablation versus patients not treated with AF ablation at a nationwide level and to analyse whether the possible benefit with AF ablation may differ among patients younger or older than 75 yo. Methods This French longitudinal cohort study was based on the national hospitalization PMSI (Programme de Médicalisation des Systèmes d'Information) database covering hospital care from the entire population. We included all patients, over 18 years old, with AF from January 2010 to December 2015. Results Among the 1,663,284 patients identified with AF, 28,018 patients were treated with AF ablation (28% female, mean age 60±10 yo) and 1,635,266 did not have AF ablation (48% female, mean age 78±11 yo). Among those treated with AF ablation, 1,605/28,018 patients (5.7%) were aged >75 yo. During follow-up (456±546 days), hospitalization with a primary diagnosis of HF and death were recorded. Incidences of hospitalization for HF and death were significantly lower in AF ablation group (respectively 6.09% vs 13.29% person per year, p<0.0001, and 1.49% vs 17.11% person per year, p<0.0001). These associations were confirmed in a multivariable analysis after adjustment on age and other comorbidities (HR 0.66, 95% CI 0.63–0.69, p<0.0001 for HF and HR 0.21, 95% CI 0.19–0.23, p<0.0001 for all-cause death). Results were significant and relatively similar whether patients were aged below or above 75 yo: HR 0.63, 95% CI 0.60–0.66, p<0.0001 when age <75 yo and HR 0.60, 95% CI 0.51–0.70, p<0.0001 when age >75 yo for hospitalization for HF; HR 0.21, 95% CI 0.19–0.24, p<0.0001 when age <75 yo and HR 0.36, 95% CI 0.29–0.45, p<0.0001 when age >75 yo for all-cause death. Conclusion In the nationwide analysis of unselected AF patients seen in hospitals, AF ablation was independently associated with a lower risk of hospitalization for HF and death whether patients were aged below or above 75 yo." @default.
