Atrial fibrillation (AF) is the most common sustained arrhythmia encountered in clinical practice and an important contributor to cardiovascular morbidity and mortality. Although the exact mechanisms behind AF are not completely elucidated, the underlying pathophysiological changes have been well described. Predisposal factors for AF include the older age, the increased left atrial size, the decreased left atrial function, the presence of heart failure and left ventricular systolic dysfunction and the presence of coronary heart disease or pulmonary or mitral valve disease.

Mammalian hearts contain a family of peptides with potent natriuretic, diuretic, and vasorelaxant actions. In addition to atrial natruretic peptide (ANP) and brain natriuretic peptide, recent studies in humans and animals have suggested that the N-terminal ANP prohormone fragment 31-67 may represent another adaptive mechanism to achieve body fluid homeostasis. Furthermore, these investigations have also suggested that via different mechanisms of action on target organisms, the C-terminal hormone ANP 99-126 and pro-ANP 31-67 may coordinate and contribute to the regulation of hemodynamic and renal function in pathophysiologic situations, such as heart failure.
