Aldosteron and end-organ damage


Several clinical studies have shown that blocking the action of aldosterone with mineralocorticoid receptor (MR) blockers in addition to angiotensin (Ang) II inhibitors reduces the mortality of patients with ischemic heart disease by further 30 %. Recent animal data suggest that is a main pathogenic factor for the development of end-organ damage. The role of locally produced and its receptor MR is not well understood. We have shown in vitro can potentiate Ang II-induced early signaling. The conjoining pathway for this interaction has not been characterized so far and the role of the MR remains to be illucidated.
