Abstract

BACKGROUND: Aging is one of the major concerns and determinants of the indications for catheter ablation (CA) for atrial fibril-lation. This study aimed to assess the safety of CA in older patients with atrial fibrillation undergoing CA. METHODS AND RESULTS: The JROAD-DPC (Japanese Registry of All Cardiac and Vascular Diseases-Diagnosis Procedure Combination) is a nationwide claims database using data from the Japanese Diagnosis Procedure Combination/Per Diem Payment System. Among 6 632 484 records found between April 2012 and March 2018 from 1058 hospitals, 135 299 patients with atrial fibrillation (aged 65±10 years, 38 952 women) who underwent CA in 456 hospitals were studied and divided into the following age groups: <60, 60 to 64, 65 to 69, 70 to 74, 75 to 79, 80 to 84, and ≥85 years. The overall in-hospital complication rate was 3.4% (cardiac tamponade 1.2%), and in-hospital mortality was 0.04%. Older patients had a higher prevalence of women, lower body mass index, and a higher burden of comorbidities such as hypertension, and all of those characteristics were predictors for complications in multivariate analysis. A multivariate adjusted odds ratio revealed that increased age was independently and significantly associated with overall complications (60–64 years, 1.19; 65–69 years, 1.29; 70–74 years, 1.57; 75–79 years, 1.63; 80–84 years, 1.90; and ≥85 years, 2.86; the reference was <60 years). CONCLUSIONS: The nationwide JROAD-DPC database demonstrated that the frequency of complications following CA in patients with atrial fibrillation increased according to age.
