Abstract

To the Editor: Aldosterone is known to induce cardiovascular dysfunction, including fibrosis, inflammation, and endothelial dysfunction, as well as thrombosis formation.1 Clinical trials have shown aldosterone to be an independent predictor of increased mortality in patients with chronic heart failure,2 and high circulating plasma aldosterone levels predict the clinical outcome in patients after myocardial infarction.3 Mineralocorticoid receptor blockade proved to exert beneficial effects in clinical trials, such as the Randomised Aldactone Evaluation Study and the Eplerenone Post-Acute Myocardial Infarction Heart Failure Efficacy and Survival Study.4 Recent studies provided evidence for a role of aldosterone in the pathogenesis of arteriosclerosis.5 However, the exact mechanisms of adverse aldosterone actions in the cardiovascular system are largely unknown. Here, we aimed at elucidating rapid (60 minutes) aldosterone effects on interactions between endothelial cells and leukocytes. …
