Gene Expression Profiles for the Identification of Prevalent Atrial Fibrillation

BACKGROUND: Diagnosis of atrial fibrillation (AF) can be difficult, requiring cumbersome investigations. We aimed to determine the association of established whole-blood gene expression scores with prevalent AF and to evaluate their performance for the identification of AF in a SIRS (Steroids in Cardiac Surgery) trial cohort. METHODS AND RESULTS: Whole-blood, transcriptome-wide gene expression profiling was performed using the Illumina …
