Takotsuba Cardiomyopathy

Aka: Takotsuba Cardiomyopathy, Stress Cardiomyopathy, Broken Heart Syndrome, Stress Induced Cardiomyopathy
  1. Definition
    1. Abrupt onset Left Ventricular Systolic Dysfunction as a response to severe emotional or physiologic stress
  2. Epidemiology
    1. Prevalence: 0.02% of hospitalized patients
    2. Ages 50 to 70 most commonly affected
    3. Primarily in women (95% of cases)
    4. Accounts for 1-2% of presumed STEMI cases
  3. History
    1. Initially described in Japan (1990)
    2. Takotsuba is Japanese for a ceramic octopus trap (which resembles the heart on Echocardiogram)
  4. Pathophysiology
    1. Postulated cause as Catecholamine surge that results in heart Muscle injury and a drop in contractility
    2. Transient with often a full recovery without significant residual Cardiomyopathy by 2 weeks
  5. Risk Factors
    1. Major stressors (85%-89% report a stressful event in the preceding 12 hours)
    2. Stress examples
      1. Emotional stressors (e.g. fear, grief, anger)
      2. Physical stressors (e.g. Cerebrovascular Accident)
      3. General Surgery
      4. Chemotherapy
      5. Exogenous Catecholamines such as beta Agonists (e.g. Albuterol, Phenylephrine)
  6. Symptoms
    1. Mimics Acute Coronary Syndrome
    2. Chest Pain
    3. Shortness of Breath
  7. Signs
    1. May present with Cardiogenic Shock or lethal Arrhythmia (e.g. VT/VF, PEA)
  8. Labs
    1. Serum Troponin
      1. Frequently increased
  9. Diagnostics
    1. Electrocardiogram
      1. May mimic ST Elevation Myocardial Infarction
      2. Deep T Wave Inversions and ST Depression
      3. May demonstrate contiguous lead ST Elevation with reciprocal changes
        1. Frequently affects the anterior distribution and to a lesser extent inferior distribution
    2. Echocardiogram
      1. Acute, severe Systolic Dysfunction (with ejection fraction dropping from normal to <25-35%)
      2. Echocardiogram demonstrates reduced contractility not explained by single vessel disease
      3. May demonstrate apical ballooning of the left ventricle
      4. Heart assumes elongated shape (Japanese octopus trap)
      5. Akinetic apex
    3. Angiogram
      1. No occlusive vascular disease identified to explain the event
  10. Management
    1. Supportive care
    2. Start by treating as Acute Coronary Syndrome and exclude STEMI
    3. Manage Arrhythmias as needed
    4. Manage Cardiogenic Shock and Acute Pulmonary Edema
      1. See Cardiogenic Shock for emergent management
      2. Beta Blockers and ACE Inhibitors are commonly used for Takotsuba
      3. Consider Diuretics
      4. Anticoagulation may be considered (if decreased left ventricle wall motion)
      5. Consider Endotracheal Intubation
      6. Consider Intra-aortic balloon pump
  11. Prognosis
    1. Initial aggressive management is critical for good prognosis
    2. Ejection Fraction returns to normal (at least >50%) in nearly all cases (100% in the Sharkey study)
      1. Typically normalizes after first month
    3. Mortality 2% during hospitalization
    4. Recurrence in 5-6%

Takotsubo Cardiomyopathy (C1739395)

Definition (MSH) A transient left ventricular apical dysfunction or ballooning accompanied by electrocardiographic (ECG) T wave inversions. This abnormality is associated with high levels of CATECHOLAMINES, either administered or endogenously secreted from a tumor or during extreme stress.
Definition (NCI) A rare disorder characterized by transient left ventricular wall systolic dysfunction, resulting in apical ballooning appearance, chest pain, and ST segment elevation.
