Core Tip
Core Tip: Pheochromocytomas release massive amounts of catecholamines that can cause life-threatening cardiovascular complications, including cardiac arrhythmia, ST and non-ST segment elevation myocardial infarction, heart failure, and hypertensive urgency. For acute myocardial infarction with unexplained erratic blood pressure, headaches, palpitations, and sweating, pheochromocytoma should be considered a differential diagnosis. Pheochromocytoma is a non-atherosclerotic cause of myocardial infarction. The myocardial cell lesions may be caused by tachycardia, coronary artery spasm, or cardiomyopathy, which are related to excess catecholamines. Pheochromocy-toma with erythrocytosis is rarely reported. Elevated hematocrit contributes to increased blood viscosity and thus, to higher risk of coronary heart disease.
