A Case of Pheochromocytoma Crisis with Acute Myocardial Infarction Induced by Glucocorticoids Administration

Abstract

The most common symptoms of pheochromocytoma are paroxysmal or sustained hypertension, or symptoms of paroxysmal adren-ergic stimulation such as palpitation, headache, and diaphoresis. These patients can on rare occasion reveal or be complicated with cardiovascular symptoms such as arrhythmia, cardiomyopathy, acute coronary syndrome and cardiogenic shock. These cardiac manifestations of pheochromocytoma may delay the diagnosis, which can cause a catastrophic outcome. A pheochromocytoma cri-sis is provoked by surgery, anesthesia, exercise and, several drugs and it is known to be an endocrine emergency with mortality as high as 85%. Many classes of drugs are well known to precipitate adverse reactions, but the presentation of pheochromocytoma af-ter the administration of steroid has rarely been reported. We report here on a case of pheochromocytoma crisis with acute myocar-dial infarction after the patient took prednisolone. Furthermore, we discuss the mechanism of glucocorticoid induced crisis and myocardial infarction in pheochromocytoma patients. (
