Direct Evidences for Sympathetic Hyperactivity and Baroreflex Impairment in Tako Tsubo Cardiopathy
BACKGROUND The exact pathophysiology of Tako-Tsubo cardiomyopathy (TTC) remains unknown but a role for sympathetic hyperactivity has been suggested. Up to now, no direct evidence of sympathetic nerve hyperactivity has been established nor involvement of sympathetic baroreflex identified. The aim of our study was to determine, by direct sympathetic nerve activity (SNS) recording if sympathetic n...
متن کاملCardiac sympathetic activity in hypertrophic cardiomyopathy and Tako-tsubo cardiomyopathy
123I-meta-iodobenzylguanidine (123I-mIBG) scintigraphy has been established as an important technique to evaluate cardiac sympathetic function and it has been shown to be of clinical value, especially for the assessment of prognosis, in many cardiac diseases. The majority of 123I-mIBG scintigraphy studies have focused on patients with cardiac dysfunction due to hypertension, ischemic heart dise...

Tako-tsubo Cardiomyopathy (TTC) is typically precipitated by sudden emotional or physical stress, and is associated with excessive sympathetic stimulation and catecholamine release. Its clinical presentation is similar to that of acute coronary syndrome. The diagn...
