Q

Takotsubo cardiomyopathy

A

Transient regional systolic dysfunction of the LV that can imitate an MI but is associated with absence of significant obstructive CAD or evidence of plaque rupture, often seen in post menopausal women exposed to physical or emotional stress thought to be due to possible catecholamine surge, WILL see EKG findings such as ST elevations in 3 consecutive leads and cardiac enzymes are often positive, but coronary angiography shows absence of plaque rupture or obstruction
