1. Takotsubo cardiomyopathy is a syndrome of transient left ventricular dysfunction resulting in apical ballooning that mimics ST-elevation myocardial infarction. 2. It is typically triggered by severe emotional or physical stress and is more common in post-menopausal women. 3. While symptoms and test results can appear similar to a heart attack, coronary angiography shows no significant arterial narrowing, and left ventricular function typically recovers within weeks.

15.  Cardiomyopathy characterized by transient apical and
midventricular LV dysfunction in the absence of
significant coronary artery disease that is triggered by
emotional or physical stress.
• In setting of depressed/abnormal function of distal and apical LV
segments there is compensatory hyperkinesis of basal walls 
“ballooning” of apex during systole.
 Typically recover normal LV function in 1-4 weeks.

16.  1st described in Japan in 1990
 Named after the tako-tsubo,
which is an octopus trap
• Shape of the trap is similar
to the appearance of LV
apical ballooning noted in
patients with this form of
cardiomyopathy
 Was later described in many
other reports and was
subsequently recognised as a
distinct entity

20.  May account for up to 2% of suspected ACS
 In-hospital mortality ranges between 0-8%
 Much more common in women (~90%),
especially postmenopausal women (>80% of
cases)
 Mean age 58-75 years
 More common in industrialised nations
 Many recognised triggers: death of loved one,
other catastrophic news, devastating financial
losses, natural disasters, physical illness/ICU,
etc.
Colin Farquharson , Cardiologist , Grimsby UK

21. 1. Transient a/dyskinesis of apical and midventricular
segments in association with regional wall motion
abnormalities that extend beyond the distribution of a
single epicardial vessel
2. Absence on angiography of obstructive coronary artery
disease or evidence of acute plaque rupture
3. New ST segment elevation or T wave inversions on
ECG
4. Absence of recent significant head trauma, intracranial
bleeding, phaeochromocytoma, myocarditis, or
hypertrophic cardiomyopathy
Proposed by Bybee, et al. 2004. Annals of Internal Medicine. 141: 858-865.

26.  Catecholamine excess
• Norepinephrine levels are very elevated in ~75% in some studies
• Plasma catecholamines significantly higher than in cases of MI
• May induce microvascular spasm or dysfunction myocardial
stunning or direct myocardial toxicity
• Limited endomyocardial biopsy data c/w histologic signs of
catecholamine toxicity
 Coronary artery spasm or microvascular spasm
 Myocarditis
 Post-menopausal downregulation of oestrogen
receptors
 Dense distribution of cardiac adrenoceptors in LV
apex of women > men
Colin Farquharson , Cardiologist , Grimsby UK

27.  Substernal chest pain (but not always)
 ECG abnormalities
• ST elevation (usually anterior leads)- 82%
• ST depression
• T wave inversion
• QT prolongation
• Abnormal Q waves
 Elevated cardiac biomarkers
 Dyspnoea
 Shock – similar haemodynamically to cardiogenic shock
 Syncope / feeling of “doom”

28. Colin Farquharson , Cardiologist , Grimsby UK

29.  Tachyarrhythmias, bradyarrhythmias
 Pulmonary oedema
 Cardiogenic shock
 Transient LV outflow tract obstruction
 Mitral valve dysfunction
 Acute thrombus formation and stroke
 Death

30.  Because presentation is similar to ACS, management is
usually similar in initial stages.
 LV ventriculogram and/or echocardiography can both be
used to visualize apical ballooning with a/dyskinesis of
apical ½ to ⅔ of the LV.
• Average LV EF range 20-49%
• Can have “atypical” ballooning of the middle or basal portions of
the LV (much less common)
• Wall motion abnormalities typically involve the distribution of more
than one coronary artery
 Ventriculography and echocardiography also allow
evaluation for LV outflow tract obstruction (~16%).
 Cardiac catheterization reveals lack of flow limiting
coronary lesions or evidence of plaque rupture.Colin Farquharson , Cardiologist , Grimsby UK

31.  Supportive, conservative therapy
• Hydrate, remove / reduce stress (if possible)
 Treat LV dysfunction with standard heart failure
regimen- including beta blocker, ACE inhibitor,
diuretics (if volume overloaded), aspirin
• Usually treated for ~6 months
 For pts who are hypotensive with shock, perform
echo to evaluate for LVOT obstruction.
• No LVOT obstruction inotropes, IABP if needed
• +LVOT obstruction NO inotropes (can worsen obstruction), use
beta blockers (+/- α-agonist phenylephrine), IABP if needed
• +/- fluid resuscitation (evaluate pulmonary status)
Colin Farquharson , Cardiologist , Grimsby UK

32.  0-8% in-hospital mortality, likely closer to 1-2% if
optimally treated
 Recovery of LV function, typically in 1-4 weeks
 Late sudden death (rare) and recurrent disease
(<10%) have been reported
Overall, good prognosis. If
patient survives the acute
phase, long-term prognosis
is excellent.
