Adrenal gland-released vasostatin-I is a myocardial depressant factor.

ABSTRACT: Pheochromocytoma crisis is an exceptional consequence of the release of storage vesicles of the adrenal medulla. It is complicated by fulminant adrenergic myocarditis. It offers a unique opportunity to detect inotropic negative factors from neuroendocrine origin. Our objectives were (a) to describe a pheochromocytoma crisis, (b) to investigate in vivo myocardial depressant activities for the N-terminal 1-76 Chromogranin A-derived peptide, vasostatin-I (VS-I). A patient with a pheochromocytoma crisis was treated, including extracorporeal membrane oxygenation, until mass resection. Plasma concentrations of VS-I were time-dependently assessed with a specific immunoassay; correlations with invasive cardiovascular parameters were investigated. Increased VS-I concentrations were observed over 7
