After combining an extensive clinical background with non-invasive measurements and cardiac tissue, we will look for: (1) the combination of genetic data of blood and tissue in combination with data on structural remodelling, which would give insight into the different genes involved in structural remodelling; (2) the possible association or predisposing role of structural remodelling in atrial fibrillation (AF) and AF development; (3) the difference in genetic expression in association with different types of AF and the genetic markers for predisposition for postoperative atrial fibrillation (POAF) development. eQTLs expression quantitative trait loci, mRNA messenger RNA
