Takotsubo cardiomyopathy (TC) is a transient stress-induced cardiomyopathy with left ventricular dysfunction of unknown etiology. A well accepted theory for the pathophysiology of TC is attributed to a massive catecholamine release [1]. This case report will review a chronic tetraplegia patient who was diagnosed with TC after a severe episode of autonomic dysreflexia (AD). He experiences mild episodes of AD several times a day; however, he had never experienced the severity of symptoms that was associated with this episode which led to his hospitalization. Autonomic dysreflexia is a syndrome of imbalanced sympathetic input secondary to loss of descending central sympathetic control in spinal cord injury due to noxious stimuli below the level of the injury, which occurs when the injury level is at thoracic level 6 (T6) or above [2]. In this specific case, it is presumed that the massive catecholamine release associated with this severe AD episode resulted in TC. Although TC has been diagnosed after other instances of acute stress, it is unknown for it to be diagnosed after AD in a chronic setting. The long-term effects of AD have not been well studied, and this case illustrates the importance of education to recognize and manage AD in the spinal cord patient who frequently has episodes of AD.
心尖球形综合征(Takotsubo cardiomyopathy,TC)是一种短暂的应激诱导性心肌病,病因不明,左心室功能障碍。TC 的病理生理学有一个被广泛接受的理论,归因于大量儿茶酚胺的释放[1]。本病例报告将回顾一位慢性四肢瘫痪患者,在严重自主神经反射异常(autonomic dysreflexia,AD)发作后被诊断为 TC。他每天会经历几次轻度 AD 发作;然而,他从未经历过与这次发作相关的严重症状,导致他住院治疗。自主神经反射异常是一种由于脊髓损伤导致的下行中枢交感控制丧失而引起的交感输入失衡综合征,通常发生在损伤水平在胸 6 节段(T6)或以上的情况下[2]。在这个特定的病例中,据推测,与严重 AD 发作相关的大量儿茶酚胺释放导致了 TC。虽然 TC 已经在其他急性应激发作后被诊断出来,但在慢性 AD 中被诊断出来的情况尚不清楚。AD 的长期影响尚未得到充分研究,本病例说明了对经常发生 AD 的脊髓损伤患者进行 AD 识别和管理的教育的重要性。
