[Acute myocardial damage from a pheochromocytoma]

Area of Science:

• Cardiology
• Endocrinology
• Oncology

Background:

• Cardiac involvement in pheochromocytoma is uncommon but can lead to severe clinical decline.
• Early recognition is crucial for appropriate management and preventing adverse outcomes.

Observation:

• A 70-year-old woman presented with chest discomfort, labile blood pressure, and dyspnea, initially suspected of acute myocardial infarction.
• Echocardiogram revealed severe left ventricular hypokinesia without segmental wall motion abnormalities, and cardiac biomarkers were normal.

Findings:

• Coronary angiography showed normal coronary arteries, ruling out obstructive coronary artery disease.
• Elevated urinary catecholamines confirmed pheochromocytoma, a rare adrenal tumor.
• The patient experienced significant hypertension during surgery and hypotension post-tumor removal.

Implications:

• This case underscores the importance of considering pheochromocytoma in patients with unexplained cardiac dysfunction and hypertension.
• Prompt diagnosis and management of pheochromocytoma are vital to prevent life-threatening cardiovascular complications.
• Multidisciplinary care involving cardiology, endocrinology, and surgery is essential for optimal patient outcomes.
