5-hydroxytryptamine and atrial fibrillation: how significant is this piece in the puzzle?

Abstract

5-Hydroxytryptamine, a recent addition to the list of hormonal triggers for atrial fibrillation (AF), may play a pivotal role in the induction of AF related not only to cardiac surgery but also to acute coronary syndromes, valvular heart disease, cardiomyopathies, alcoholism, aging, and conducting tissue disease. This review examines the supporting laboratory and clinical evidence and provides a comprehensive insight into the basic underlying mechanisms involved. It also delves into the potential benefits and limitations of 5-HT4 antagonists in the prevention and management of this arrhythmia.
