Stress cardiomyopathy clinical presentation mimics an acute coronary syndrome. It is characterized by left ventricular multi-segmental commitment, absence of significant coronary artery disease and by the complete resolution of all the findings. Its pathophysiology is not yet clear, but the main theory suggests a catecholamine-mediated cardiotoxicity mechanism. Pheochromocytoma is a neuroendocrine tumor producer of catecholamines with several cardiovascular manifestations. We report a case of stress cardiomyopathy that was the first clinical manifestation of an unknown pheochromocytoma.
应激性心肌病的临床表现类似于急性冠状动脉综合征。其特征为左心室多节段受累、无明显冠状动脉疾病且所有表现均可完全缓解。其病理生理学尚不清楚，但主要理论认为是一种儿茶酚胺介导的心脏毒性机制。嗜铬细胞瘤是一种产生儿茶酚胺的神经内分泌肿瘤，有多种心血管表现。我们报告一例应激性心肌病病例，它是一例未知嗜铬细胞瘤的首发临床表现。
