Pheochromocytoma presenting as acute non-ST elevation myocardial infarction following elective hysterectomy
Insights
Pheochromocytoma, a rare adrenal tumor, significantly increases cardiovascular event risk. Early suspicion in patients with myocardial events and hypertension is crucial for timely diagnosis and management.
Area of Science:
- Cardiology
- Endocrinology
- Oncology
Background:
- Pheochromocytoma is associated with a 14-fold increased risk of cardiovascular events compared to essential hypertension.
- Adrenal tumors like pheochromocytoma can secrete catecholamines, leading to significant physiological effects.
Observation:
- A 47-year-old female presented with elevated troponins and ST depression post-hysterectomy.
- Cardiac catheterization revealed labile hypertension and tachycardia, but no coronary artery disease.
- Imaging identified a left adrenal mass, and biochemical tests confirmed pheochromocytoma.
Findings:
- Surgical removal of the pheochromocytoma resolved the patient's symptoms.
- Post-adrenalectomy, the patient was asymptomatic and required minimal antihypertensive medication.
Implications:
- Prompt diagnosis of pheochromocytoma in patients with unexplained cardiac events and hypertension is vital.
- Early identification prevents unnecessary cardiac procedures and guides appropriate preoperative management.
- This case highlights the importance of considering pheochromocytoma in the differential diagnosis of acute cardiovascular events.
Introduction:
Studies have shown patients with pheochromocytoma have a 14-fold higher rate of cardiovascular events than patients with essential hypertension.
Case Presentation:
A 47-year-old female was found to have elevated troponins and marked ST depression following elective hysterectomy. The patient underwent cardiac catheterization, and labile blood pressures with a narrow-complex tachycardia were noted during the procedure. No evidence of coronary artery disease or wall motion abnormality was found. After catheterization, the patient complained of abdominal pain with difficulty passing gas. CT abdomen/pelvis revealed a 4.3 x 5 cm left adrenal mass. Plasma metanephrines and 24-hour urine catecholamines suggested pheochromocytoma. She underwent left total adrenalectomy, and pathology confirmed pheochromocytoma. At 3-month follow-up, she was asymptomatic and required only one agent for blood pressure control.
Discussion:
Suspecting pheochromocytoma in patients with an unexpected myocardialevent and labile hypertension can lead to prompt diagnosis and appropriate preoperative management as well as avoidance of unnecessary procedures.
