Aims: We aim to evaluate the incidence of atrial fibrillation (AF) in a large real-world cohort of patients implanted with an insertable cardiac monitor (ICM) who had a clinical history of symptomatic heart failure (HF) with reduced or preserved left ventricular ejection fraction (LVEF).
Methods: Patients with an ICM and a history of HF events were identified from the Optum® de-identified Electronic Health Record dataset merged with an ICM device dataset collected during 2007-2021. All ICM-detected AF episodes that were available with ≥30-s of ECG at onset were adjudicated using artificial intelligence (AI model).
