1 The Authors' Reply We would like to thank Dr. Hassan for your interest in our recently published study “Association between changes in heart rate and adverse events in patients with non-valvular atrial fibrillation: A post hoc analysis of the J-RHYTHM Registry.” [1] There were several limitations in our study as already mentioned in the article [1]. Our replies to the comments are as follows. First, we agree that heart rate (HR) fluctuation may have influenced the incidence of adverse events.

Introduction Atrial fibrillation (AF) and heart failure (HF) are common in the elderly population and often exist concomitantly.1 Coexistence of HF with AF can affect the prognosis of patients with AF.2-5 However, the association between the coexistence of HF and the risk of clinical events may be indirect or attenuated because elderly AF patients may have more comorbidities and heart damage, and older age itself is strongly associated with stroke, HF, and mortality.1, 6, 7 Direct oral...

JACC Journals › JACC: Asia › Archives › Vol. 3 No. 3_Part_2 AbstractBackgroundAdvancing age, decreasing renal function, and atrial fibrillation are strongly associated. Real-world evidence of direct oral anticoagulant (DOAC) use among elderly patients ≥75 years of age with nonvalvular atrial fibrillation and renal dysfunction is limited. ObjectivesThis study sought to assess 2-year outcomes and anticoagulant treatment, stratified by renal function.
