[Aldosterone receptor antagonists in heart failure. Rightly brought back from retirement].

There is growing evidence that aldosterone plays an important role in the development of endorgan-damage e.g. vascular and cardiac fibrosis, remodeling and endothelial dysfunction. Aldosterone-antagonism has become a novel therapeutic principle beyond its sodium retention properties in the treatment of cardiovascular diseases. In patients with severe left ventricular dysfunction spironolactone could reduce death and hospitalisation. A new selective aldosterone antagonist, eplerenone, was effective in patients with left ventricular dysfunction after myocardial infarction added to optimal medical therapy.
