Suppression of persistent atrial fibrillation by genetic knockdown of caspase 3: a pre-clinical pilot study

Abstract excerpt

AIMS: Atrial fibrillation (AF) is linked to cardiomyocyte apoptosis, leading to atrial remodelling and reduction in electrical conduction velocity. We hypothesized that genetic suppression of an apoptotic key enzyme, caspase 3, would prevent the development of persistent AF by reducing apoptosis which may serve as an arrhythmogenic substrate. METHODS AND RESULTS: Atrial fibrillation was induced in domestic pigs...
