醛固酮由肾上腺皮质球状带细胞分泌并参与水盐代谢,在心血管系统醛固酮参与氧化应激,诱导心肌纤维化从而参与心肌重构,醛固酮也影响心肌离子流和心肌复极从而与异位电活动有关。
Aldosterone is secreted by the adrenal cortical zone cells and participates in water and salt metabolism. Aldosterone participates in oxidative stress and induces myocardial fibrosis in the cardiovascular system, thereby participating in myocardial remodeling. Aldosterone also influences myocardial ion flux and myocardial repolarization and thus is related to electrical activity of the ectopic body .
