Stress-induced cardiomyopathy, also known as Takotsubo cardiomyopathy and left ventricular apical ballooning syndrome, is characterized by transient systolic dysfunction of the apical and mid-segments of the left ventricle with the abscence of coronary occlusion, This disease typically occurs in postmenopausal women of an advanced age after emotional or physical stress. Although the prognosis is generally favorable, acute fatal complications have been reported in a small subset of patients. Some patients died with acute cardiac complications, on the other hand, other patients died with underlying critical illness which triggered stress-induced cardiomyopathy.
