takotsubo cardiomyopathy

(redirected from Tako-tsubo syndrome)
A non-ischaemic cardiomyopathy most common in post-menopausal women, which is characterised by a sudden temporary weakening of the myocardium triggered by physical or emotional stress—e.g., death of a loved one—hence the alternate term, broken heart syndrome
Pathogenesis High serum catecholamines—adrenaline/ epinephrine
Diagnosis Negative coronary angiogram
Prognosis If the individual survives the initial event, the left ventricular function improves within 2 months

takotsubo cardiomyopathy

Reversible dysfunction of the left ventricle. It may be the cause of transient heart failure that occurs after exceptionally stressful events. The heart in such instances takes on a rounded shape with a narrow neck, resembling a traditional Japanese lobster trap (takotsubo). It is informally called broken-heart syndrome.
Synonym: apical ballooning syndrome; stress-induced cardiomyopathy; transient left ventricular apical ballooning

Conventional coronary angiography was performed in all patients and revealed the two-vessel disease in more than half of the patients, only one patient having normal coronary arteries (the Tako-Tsubo syndrome).
Called Tako-Tsubo syndrome, or stress-induced cardiomyopathy, it is a rare disease, which at first used to be confused with the far more common (and dangerous) cardiac infarction or heart attack.
