Reversible Left Ventricular Dysfunction with Apical Ballooning-A Case Report of Ampulla Cardiomyopathy
可逆性左心室功能不良合併頂部氣球狀突起－一壺腹狀心肌病變病例報告
摘要
壺腹狀心肌病變是一種罕見的疾病，其特徵是短暫的左心室頂部氣球狀突起卻無明顯的冠狀動脈疾病，在急性期左心室的形狀類似壺腹。這些病人常被誤診為急性心肌梗塞因為兩者有相似的臨床症狀、心電圖變化和心臟酵素升高。雖然此種疾病確切的成因還不清楚，但臨床表現和預後通常不錯。我們報告一位62歲壺腹狀心肌病變的女性個案並探討其可能的機制。和Catecholamine有關的微循環功能不全是最可能的原因。
並列摘要
Ampulla cardiomyopathy is a rare cardiac syndrome characterized by transient left ventricular (LV) apical ballooning without significant coronary artery disease. The shape of the left ventricular cavity during the acute phase resembles an ampulla. These patients are usually misdiagnosed as acute myocardial infarction because of similar clinical symptoms, electrocardiogram (ECG) changes and myocardial enzyme elevation. The precise etiology remains unclear. However, the clinical course and prognosis are usually benign. We report a 62-year-old woman with ampulla cardiomyopathy and discussed the possible pathogenesis involved. Catecholamine-related microcirculation dysfunction appears to be the most likely etiology.
