Key result
Takotsubo cardiomyopathy is a rare syndrome mimicking ST-elevation myocardial infarction that carries a 4% to 5% mortality rate and requires emergent coronary angiography for differentiation.
Takotsubo cardiomyopathy is not entirely benign, carrying a 4-5% mortality rate, and necessitates emergent coronary angiography for definitive diagnosis due to its clinical overlap with STEMI.
Alerts clinicians to its mortality risk in STEMI-like presentations; leaves open prospective studies on targeted management.
Takotsubo cardiomyopathy (TC), a rare syndrome often preceded by an emotional or physical trigger, which earned the nickname broken heart syndrome, was first diagnosed in 1990. Takotsubo cardiomyopathy can mimic an ST-elevation myocardial infarction (STEMI). Originally, TC was thought to be self-limiting and benign. However, there is a 4%-5% mortality rate, which is associated with serious complications. The majority of people diagnosed with TC are postmenopausal women, but it can affect all ages. Patients will often present to the emergency department with chest pain and dyspnea. An electrocardiogram (ECG) often demonstrates ST elevation. There is no definitive way to differentiate between TC and STEMI on an ECG. Therefore, all patients need to have emergent coronary angiography with left ventriculography.
