takotsubo cardiomyopathy
Pronunciation: tah-kot-SOO-bo kar-dee-oh-my-OP-ah-thee
A form of reversible cardiomyopathy triggered by severe emotional or physical stress, characterized by transient dysfunction of the left ventricle.
Full Definition
Takotsubo cardiomyopathy, also known as stress cardiomyopathy or broken heart syndrome, is a temporary condition where the heart muscle becomes suddenly weakened due to severe stress. The left ventricle changes shape, resembling a Japanese octopus trap (takotsubo), causing symptoms similar to a heart attack. Unlike myocardial infarction, there is no coronary artery blockage, and the condition is typically reversible within weeks to months. It predominantly affects postmenopausal women and can be triggered by emotional trauma, physical stress, or medical procedures.
Usage
Usage note: Often misspelled as 'tako-tsubo' with a hyphen; the correct spelling is one word. Japanese origin should be noted when explaining to lay audiences.
