This is not Dr. Conn's aldosterone anymore.

In 1955, Dr. Jerome Conn described a patient with severe hypertension and hypokalemia and an aldosterone-secreting adenoma. The prevalence of hyperaldosteronism is increased among patients with obesity or resistant hypertension. Angiotensin-converting enzyme (ACE) inhibitors and angiotensin receptor blockers reduce the secretion of aldosterone, but with chronic treatment aldosterone concentrations "escape" back to baseline values. Mineralocorticoid receptor (MR) antagonism reduces mortality in patients with heart disease who are already taking an ACE inhibitor and diuretic. In addition to affecting sodium and potassium homeostasis via classical MR-dependent pathways, aldosterone induces inflammation and causes cardiovascular remodeling and renal injury. Some of these effects involve MR-independent pathways. At the same time, ligands other than aldosterone can activate the MR. This paper reviews mechanism(s) for the proinflammatory and profibrotic effects of aldosterone and presents data indicating that endogenous aldosterone, acting at the MR, contributes to many of the pro-inflammatory and pro-fibrotic effects of angiotensin II in vivo.
