Pheochromocytoma presenting with chest pain, heart failure and elevated pancreatic enzymes

Pheochromocytoma can present with various clinical manifestations and potentially mislead physicians by mimicking other conditions. Here we report a patient presenting with acute chest pain, de Winter electrocardiogram (ECG) changes, and elevated troponin I; the patient was initially diagnosed with acute myocardial infarction, but coronary angiography revealed no significant stenosis. He experienced heart failure symptoms with elevated serum amylase, lipase, and catecholamines. Further examination confirmed the diagnosis of pheochromocytoma, the patient later underwent tumor resection and recovered well. This case highlights the importance of rapid recognition and management of pheochromocytoma.
