First identified in 1992 in Japan, Takotsubu Cardiomyopathy is a stress-induced cardiomyopathy that presents identically to ST-segment elevated myocardial infarction (STEMI). Termed Broken Heart Syndrome for its correlation to stressful events such as the loss of a spouse or family member, Takotsubo is a complex phenomenon in the world of cardiac care. Over-saturation of endogenous catecholamines is the most popular explanation for this clinical condition, but other explanations such as parasympathetic nervous system dysfunction and coronary artery vasospasm are also revealing themselves as causative factors.
