Ampulla Cardiomyopathy (Takotsubo Cardiomyopathy)-A Review
摘要
The ampulla cardiomyopathy (Takotsubo Cardiomyopathy) also known as stress-induced cardiomyopathy (SICD), or broken heart syndrome, mimics acute coronary syndrome, typically characterized by transient regional systolic dysfunction involving the left ventricle apex and midventricle with hyperkinesis of the basal segments. Pathophysiology of this disease has been investigated by myocardial scintigraphy in recent years. The etiology may be related to catecholaminergic or adrenoceptor-hyperactive cardiomyopathy, but also may be mutlifactoral. In this article, we provide a brief review of the literature regarding the prevalence, the possible etiology, risk factors, electrocardiographic and echocardiographic findings, clinical manifestation, diagnostic criteria, prognosis and treatment.
