[Ischemic cardiomyopathy as a presentation of pheocromocytoma]

Area of Science:

• Cardiology
• Endocrinology
• Oncology

Background:

• Ischaemic heart disease (IHD) typically results from coronary artery disease.
• Pheochromocytoma is a rare neuroendocrine tumor of the adrenal medulla.
• The link between pheochromocytoma and IHD is infrequently recognized.

Observation:

• A patient presented with IHD symptoms.
• Coronary angiography revealed no significant coronary artery lesions.
• Subsequent investigations led to the diagnosis of pheochromocytoma.

Findings:

• Pheochromocytoma was identified as the underlying cause of the patient's IHD.
• The absence of coronary lesions highlighted an atypical presentation of IHD.
• This case underscores the diagnostic challenge posed by pheochromocytoma.

Implications:

• Pheochromocytoma should be considered in the differential diagnosis of IHD, particularly in cases lacking typical coronary findings.
• Prompt diagnosis of pheochromocytoma allows for potentially curative treatment.
• Recognizing this rare association can improve patient outcomes and prevent misdiagnosis of IHD.
