Afferent baroreflex failure and tako-tsubo cardiomyopathy

This is an excerpt from the content

Tako-tsubo is a Japanese fisherman’s octopus trapping pot. The word has become popular to describe a type of cardiomyopathy in which the left ventricle of the heart transiently balloons at the apex and mid portions and, with a little imagination, looks like a tako-tsubo [1]. Variant forms of transient left ventricular dysfunction in which the apex is not affected have also been described [2]. Additional names for this clinical syndrome are transient left ventricular dysfunction syndrome, stress cardiomyopathy or apical ballooning cardiomyopathy. Patients present similarly to those with myocardial infarction, typically with chest pain and dyspnea and with findings on electrocardiography which are characteristic of myocardial infarction such as ST segment elevation and T wave inversion [35]. However, elevation of cardiac biomarkers such as troponin is modest and, in addition, the coronary arteries show no flow-limiting stenosis on conventional angiography [3]. Tako-tsubo cardiomyopathy ...
