Pheochromocytoma with acute heart failure as a complication-emphasis on the etiology of acute heart failure for diagnosis and treatment: a case report.

BACKGROUND

The primary causes of heart failure include myocardial damage and structural abnormalities. In addition to cardiovascular disease, noncardiovascular disease can also lead to heart failure. Identifying these etiologies is critical for accurate diagnosis and timely, targeted treatment.

CASE PRESENTATION: The patient presented with a 10-month history of recurrent chest tightness and shortness of breath, with symptoms significantly worsening 6 hours before admission. She was diagnosed with acute heart failure in the decompensated phase, complicated by cardiogenic shock. Stabilization was achieved via an intra-aortic balloon pump (IABP) and veno-arterial extracorporeal membrane oxygenation (VA-ECMO). Further evaluation revealed pheochromocytoma as the underlying cause of acute heart failure. The patient underwent successful surgical resection of the pheochromocytoma, with no recurrence of heart failure symptoms observed during follow-up.

CONCLUSION

Acute heart failure is a rare but critical condition with rapid onset, often presenting as an emergency. Effective management necessitates life support therapy to stabilize the patient, allowing time for further diagnostic and therapeutic measures.
