Definition/Description[edit | edit source]
Takotsubo cardiomyopathy occurs when there is an abnormal contraction of the transient left ventricle, creating a balloon shape appearance initially during systole. The Japanese first described the heart condition around 1991. The shape of the heart resembles a Japanese octopus pot with a rounded bottom and narrow neck; hence the name tako-tsubo.[1]
Typically an intense emotional stress can trigger this type of event. High levels of catecholamines are present in these patients and can cause the heart to be stunned temporarily. This is a reversible cardiomyopathy and clinically presents as a myocardial infarction. Individuals that experience this may or may not have a cardiovascular disease.
Other names include:
—Broken heart syndrome
—Ampulla cardiomyopathy
—Stress cardiomyopathy
—Apical ballooning syndrome (ABS)
—Acute left ventricular ballooning[1]
Prevalence[edit | edit source]
Takotsubo cardiomyopathy is a very rare condition and has to be differentiated from myocardial infarct. The incidence of takotsubo cardiomyopathy is 1-2% in patients diagnosed with MI. These individuals are usually postmenopausal females (90%). The average age is 62-75 years old. There are approximately 7,000-14,000 cases of takotsubo cardiomyopathy in the U.S.[2]
Characteristics/Clinical Presentation
[edit | edit source]
Usually takotsubo cadiomyopathy is triggered by emotional stress, physical stress, non-cardiac surgery or procedure (refer to table). The onset is insidious and presents with chest pain at rest.
Table I. Stressors reported to trigger ABS[3] Emotional stress Death or severe illness or injury of a family member, friend, or pet Receiving bad news—diagnosis of a major illness, daughter's divorce, spouse leaving for war Severe argument Public speaking Involvement with legal proceedings Financial loss—business, gambling Car accident Surprise party Move to a new residence Physical stress Non-cardiac surgery or procedure—cholecystectomy, hysterectomy Severe illness—asthma or chronic obstructive airway exacerbation, connective tissue disorders, acute cholecystitis, pseudomembranous colitis Severe pain—fracture, renal colic, pneumothorax, pulmonary embolism Recovering from general anesthesia Cocaine use Opiate withdrawal Stress test—dobutamine stress echo, exercise sestamibi Thyrotoxicosis |

Signs and Symptoms of Takotsubo include[4]:[5]
• Chest pain
• Dyspnea
• Hypotension
• Syncope
• Mild to moderate HF
• Pulmonary edema
• Lab Changes
• Modest increase in troponin T levels
• Increase in creatine phosphokinase (CPK)
• Elevation in pBNP
• High levels of serum catecholamines
The most common signs and symptoms are chest pain and dyspnea; resembling a myocardial infarction.

Systemic Involvement[edit | edit source]
There are a number of possible complications in patients who present with takotsubo cardiomyopathy. Left-sided congestive heart failure with pulmonary edema, cardiogenic shock, ventricular fibrillation, left ventricular thrombus formation, and left ventricular free wall rupture are all possibilities. Death is included in this list; however, the mortality rate is only 0-8%, and generally less than 2%.[6]
