Racial Differences in Device-Detected Incident Atrial Fibrillation.

Background: Prior research suggests Black individuals have a lower risk of atrial fibrillation (AF) than White individuals, but this may be related to the underdetection of AF. Whether this trend persists using highly sensitive methods of AF diagnosis has not been well-studied.

Objectives: The objective of this study was to use cardiac implantable electronic devices (CIEDs) capable of AF diagnosis to compare AF incidence between Black and White individuals.

CHADSVASc score as a predictor of ablation success defined by continuous long-term monitoring.

Background: There are few reliable risk stratification tools for successful atrial fibrillation catheter ablation (AFCA) and most prior studies have used short-term external monitors to define success. CHADSVASc score may be useful in predicting AF recurrence. We investigated whether CHADSVASc score correlates with AFCA success as measured by continuous monitoring via cardiac implantable electronic devices (CIEDs).

Impact of atrial fibrillation ablation on activity minutes in patients with cardiac implantable electronic devices.

Background: Impaired quality of life due to atrial fibrillation (AF), which often includes decreased activity level, is an indication for ablation. However, the impact of ablation for AF on activity is poorly understood.

Objective: The purpose of this study was to assess the impact of ablation on activity minutes per day using continuous accelerometer data from cardiac implantable electronic devices (CIEDs).
