Introduction : Neuro-hormones such as the atrial natriuretic peptide (ANP), brain natriuretic peptide (BNP) and endothelin (ET) have been reported to increase the risk of stroke in atrial fibrillation (AF). Recently, emerging left atrial appendage (LAA) occlusion is performed to prevent the incidence of thrombosis, but little is known how the secretion of neuro-hormone after LAA occlusion. The study was to evaluate the effect of LAA occlusion on the secretion of ANP, BNP and ET levels at a long-term follow up.
