Abstract
Background: atrial fibrillation (AF) is the most common cardiac rhythm disorder encountered in clinical practice. It is associated with an increased risk of stroke, hospitalization, and mortality, all of which have a significant impact on healthcare economic costs. AF is often asymptomatic and is frequently underdiagnosed. In particular, paroxysmal episodes may be missed during clinical evaluation and electrocardiogram.
Aim of the Study: to investigate the incidence and predictive factors of AHREs in patients with CIEDs and without a history of AF in order to provide a reliable basis for the clinical identification of patients with a high AHRE risk.
Patients and Methods: this is a retrospective, observational data collection study conducted at a single, tertiary care center in the Pacemaker Follow up clinics at Ain Shams University hospitals. Patients with dual‐chamber CIED (dual‐chamber pacemaker, ICD, CRT‐P, and CRT‐D), visiting the device clinic during the period of May 2022 to November 2022, were eligible for this data collection protocol.
Results: according to the result of our study, we concluded that coronary artery disease, stroke/Transient ischemic attacks, left atrial volume index> 34.73 ml/m^2, left ventricular ejection fraction≤ 48%, atrial pacing percentage > 53%, and ventricular pacing percentage >97% are independent factors associated with AHREs in patients with cardiac implantable electronic devices and without a history of AF. But unfortunately, we cannot evaluate the clinical outcomes of AHREs in such patients due to the short duration of the current study and the relatively small number of patients who were included in our study.
