What is it
Stress-induced cardiomyopathy is a type of non-ischemic cardiomyopathy caused by a sudden temporary dysnfuction of the myocardium. The etiology is unclear, but thought to be related to the autonomic nervous system and an excessive release of adrenalin. The effect is possible HF, lethal ventricular dysrhythmias, and possible ventricular rupture. This condition is also known as Takotsubo, apical ballooning syndrome, or broken heart syndrome.
It is most commonly seen in postmenopasual women with a history of a recent and severe emotional or physical stress. The average age at onset is between 58-75 years. This condition is usually sudden, and acute with the heart returning to normal in about two months.
