[Perioperative treatment of patients with pheochromocytoma combined severe catecholamine cardiomyopathy: 5 cases report].

OBJECTIVE

To discuss perioperative treatment and cardiac function changes after medicine and surgical treatment of pheochromocytoma patients with severe catecholamine cardiomyopathy.

METHODS

Five pheochromocytoma patients with severe catecholamine cardiomyopathy in our hospital for the past 5 years were studied, their general characteristics, clinical manifestations, diagnosis tests summarized and the cardiac function changes before and after the treatment evaluated.

RESULTS

All the 5 patients were diagnosed definitely before operation. After medication, left ventricular ejection fraction (LVEF) of the 5 patients improved and 4 patients' LVEF increased 7-10 days after operation compared with after medication, and one patient's LVEF improved after 3 months.

CONCLUSION

Pheochromocytoma patients with severe catecholamine cardiomyopathy should have adequate medication, and their abnormal cardiac function would be reversed after surgical treatment.
