Pheochromocytoma is a rare catecholamine-secreting neuroendocrine tumor arising from chromaffin cells. Acute catecholamine-mediated cardiomyopathy secondary to pheochromocytoma is rare, but life-threatening. We report a case of a 50-year-old man who presented with chest pain with electrocardiography showing ST elevation in V2-4. He was transferred to cardiac catheterization laboratory for coronary angiography immediately. However, the results showed no evidence of coronary artery occlusions and the left ventriculography revealed hypokinesia of basal part with poor left ventricular ejection fraction. Further investigation confirmed pheochromocytoma-related reversible cardiomyopathy.
嗜铬细胞瘤是一种罕见的起源于嗜铬细胞的分泌儿茶酚胺的神经内分泌肿瘤。由嗜铬细胞瘤继发的急性儿茶酚胺介导的心肌病很罕见，但可危及生命。我们报告一例50岁男性患者，其因胸痛就诊，心电图显示V2 - 4导联ST段抬高。他立即被转至心脏导管实验室进行冠状动脉造影。然而，结果显示无冠状动脉阻塞的证据，左心室造影显示基底段运动减弱，左心室射血分数低。进一步检查确诊为嗜铬细胞瘤相关的可逆性心肌病。
