Stress cardiomyopathy (also called apical ballooning syndrome, takotsubo cardiomyopathy, broken heart syndrome, and stress-induced cardiomyopathy) is a syndrome characterized by transient regional systolic dysfunction, principally, of the left ventricle (LV), mimicking myocardial infarction (MI), but in the absence of angiographic evidence of obstructive coronary artery disease or acute plaque rupture. In most cases of stress cardiomyopathy, the regional wall motion abnormality extends beyond the territory perfused by a single epicardial coronary artery. The term takotsubo is taken from the Japanese name for an octopus trap, which has a shape that is similar to the systolic apical ballooning appearance of the LV in the most common and typical form of this disorde mid and apical segments of the LV are hypokinetic/akinetic, and there is hyperkinesis of the basal walls.   |
