The case of a patient with pheochromocytoma who presented with an unusual pattern of left ventricular dysfunction not previously described is reported. Although a triad of headaches, sweating attacks and palpitations is generally recognized as the classic mode of presentation of this pathology, this patient first presented with shock and pulmonary edema. Moreover, both echocardiography and angiography showed severe basal and mid-ventricular left ventricular dysfunction but preserved apical contractility. This hitherto unidentified finding was interpreted as being due to an afterload mismatch, rather than to an intrinsic myocardial injury, as is usually reported in such cases.
报告了一例嗜铬细胞瘤患者,其表现出一种此前未描述过的不寻常左心室功能障碍模式。尽管头痛、出汗发作和心悸三联征通常被认为是这种疾病的经典表现模式,但该患者最初表现为休克和肺水肿。此外,超声心动图和血管造影均显示左心室严重的基底段和中间段功能障碍,但心尖部收缩性保留。这一迄今未被识别的发现被解释为是由于后负荷不匹配,而非通常在此类病例中报道的心肌内在损伤所致。
