Older patients (≥75 years) had a significantly higher risk of late cerebrovascular events (CVE) after catheter ablation for atrial fibrillation, with an OR of 4.9 (P = 0.001).
Does age ≥65 years increase the risk of cerebrovascular events after catheter ablation of atrial fibrillation compared to age <65 years?
While periprocedural stroke risk is similar across age groups, patients over 65 (especially >75 years) have a higher risk of late cerebrovascular events after AF ablation regardless of rhythm, anticoagulation status, or CHADS2 score.
Absolute Event Rate: 0% vs 0%
Stroke and Atrial Fibrillation Ablation . Introduction: Factors associated with cerebrovascular events (CVEs) after radiofrequency catheter ablation (RFA) of atrial fibrillation (AF) have not been well defined in elderly patients (≥65 years). The purpose of this study was to determine the prevalence and predictors of CVEs after RFA in patients with AF ≥65 years old, in comparison to patients 4 weeks after the RFA) occurred in 15 of 508 (3%) of patients ≥65 years old (1% per year) and in 5 of 508 (1%) patients 75 years old (OR = 4.9, ±95% CI: 3.3–148.5, P = 0.001) was the only independent predictor of a CVE. Among patients 75 years old is the only independent predictor of late CVEs regardless of the rhythm, anticoagulation status, or the CHADS 2 score (Congestive heart failure, Hypertension, Age ≥ 75 years, Diabetes mellitus and prior Stroke or transient ischemic attack).
