The Prevalence of Atrial Fibrillation and Related Factors Including Anthropometric, Hemodynamic and Echocardiographic Parameters in Patients with Hemodialysis

Abstract

Introduction: Atrial fi brillation is the most common type of arrhythmia. The prevalence of atrial fi brillation is increased in hemodialysis patients. The aim of the present study was to investigate the prevalence of atrial fi brillation and related factors including anthropometric, hemodynamic and echocardiographic parameters in hemodialysis patients. Patients and Methods: We recruited 154 [72 (46.8%) woman, 82 (53.2%) man] hemodialysis patients in this study. Atrial fi brillation was determined electrocardiographically (the P waves was absent and RR intervals were irregular) and the patients were divided into two groups depending on the presence or absence of atrial fi brillation. Transthoracic echocardiography was performed in all patients. Results: There were 7 (4.5%) patients with atrial fi brillation. Although we found that the age, left ventricle end-diastolic diameter, left ventricle end-systolic diameter and left atrial diameter were increased in hemodialysis patients with atrial fi brillation, ejection fraction increased in hemodialysis patients with no atrial fi brillation. Left atrial diameter and left ventricle end-systolic diameter were shown to be independent predictors of atrial fi brillation in hemodialysis patients (p< 0.05). Conclusion: Left atrial diameter and end-systolic left ventricle diameter were independent predictors of atrial fi brillation in hemodialysis patients.
