Acute catecholamine cardiomyopathy is an uncommon, life-threatening manifestation
of pheochromocytoma. The massive release of catecholamines from the adrenal
medulla and their toxic effects on the coronary vessels and the cardiac myocytes
play a significant role in the pathogenesis of cardiomyopathy in patients with
pheochromocytoma. Severe manifestations, such as acute catecholamine
cardiomyopathy, may be the initial presentation, especially in unsuspected and
untreated pheochromocytoma cases. The clinical course of catecholamine-induced
cardiomyopathy is unpredictable as patients may rapidly deteriorate into
circulatory collapse and multisystem crisis. We report a case of a 25-year-old
man who presented with catecholamine-induced cardiomyopathy.
