Abstract :
Objective: The aim of this case study is to emphasize the importance of α-blockade in managing a rare complication of an untreated pheochromocytoma. Clinical Presentation and Intervention: A 41-year-old man with previous bilateral pheochromocytoma presented with chest pain. He was suffering from cardiac failure and persistent hypotension requiring an inotrope. Cardiac markers, an electrocardiogram and an echocardiogram confirmed acute myocardial infarct with poor ejection fraction and global hypokinesia. An 18 Ffluorodeoxyglucose PET/CT scan showed progressive left suprarenal and organ of Zuckerkandl pheochromocytomas. Blood pressure stabilisation proved challenging but was achieved by titrating an incremental dose of α-blocker against a tapering inotropic dose. Conclusion: This case showed the efficacy of an α-blocker despite persistent hypotension in a patient with pheochromocytoma-induced cardiomyopathy.
