Takotsubo cardiomyopathy, also known as broken heart syndrome or stress-induced cardiomyopathy, is a temporary heart condition characterized by a sudden and reversible heart muscle weakening. This condition is often triggered by severe emotional or physical stress, such as the death of a loved one, a sudden illness, a traumatic event, or even extreme happiness. It was first described in Japan in the early 1990s.
It was named Takotsubo due to the affected heart’s shape and resemblance to a traditional Japanese octopus trap called a takotsubo. The exact cause of Takotsubo cardiomyopathy is not fully understood. However, it is believed to be related to the sudden surge of stress hormones (such as adrenaline) that can stun or temporarily paralyze the heart muscle. This can lead to decreased blood flow and temporary left ventricle dysfunction.
Epidemiology
Takotsubo cardiomyopathy is considered rare but is being increasingly diagnosed due to improved awareness and diagnostic methods. It is estimated to account for about 1-2% of patients initially suspected to have acute coronary syndrome. The condition primarily affects postmenopausal women, particularly those over the age of 50 or 60. However, cases have been reported in men and individuals of various ages.
Takotsubo cardiomyopathy has been reported in various regions around the world. While initially more common in Japan, cases have been documented across different ethnic and geographic populations. Recurrence of Takotsubo cardiomyopathy is uncommon but has been reported. Some individuals may experience the condition more than once, either triggered by similar stressors or unrelated events.
Anatomy
Pathophysiology
The pathophysiology of Takotsubo cardiomyopathy, also known as “broken heart syndrome” or stress-induced cardiomyopathy, is not fully understood, but several mechanisms have been proposed. It is characterized by a transient and reversible heart muscle weakening, primarily affecting the left ventricle. One prominent theory suggests that a sudden surge in catecholamines (epinephrine and norepinephrine) plays a central role.
High levels of catecholamines can lead to abnormal heart muscle contractions, causing the characteristic ballooning or apical akinesis seen in Takotsubo cardiomyopathy. This surge in stress hormones is believed to result from intense emotional or physical stress, triggering myocardial stunning. In some cases, coronary artery vasospasm, or sudden constriction of the coronary arteries, has been observed in Takotsubo cardiomyopathy.
This can reduce blood flow to the heart and contribute to myocardial damage. The exact triggers for these spasms are not fully understood but may be related to the release of stress hormones. The nervous system’s response to acute stress has also been implicated in the pathophysiology. This theory suggests that a sympathetic nervous system activity surge can lead to abnormal heart contractions and microvascular dysfunction.
Etiology
The precise origin of Takotsubo cardiomyopathy remains a subject of incomplete comprehension. Several potential mechanisms have been proposed as plausible causes, each shedding light on the possible etiological pathways of this condition. These include heightened sympathetic activity leading to excess catecholamines, spasms in coronary vessels, microvascular dysfunction, diminished estrogen levels, inflammatory responses, or compromised metabolism of myocardial fatty acids.
Various risk factors have been associated with the emergence of Takotsubo cardiomyopathy. These include distressing experiences such as domestic abuse, the loss of close family members, encounters with natural disasters, involvement in accidents or severe traumas, heated arguments, setbacks in finances or gambling, the diagnosis of acute medical conditions, and even the use of stimulating substances like cocaine or amphetamines. Curiously, even positive life events have been linked to this phenomenon, a notion dubbed the “happy heart syndrome.”
Genetics
Prognostic Factors
Most individuals with Takotsubo cardiomyopathy recover fully within a matter of weeks to months. While rare, recurrence of Takotsubo cardiomyopathy has been documented in some individuals.
In most cases, individuals who have experienced Takotsubo cardiomyopathy do not suffer long-term consequences to their heart health. However, regular follow-up appointments with a healthcare provider are recommended to monitor heart function and address potential complications or concerns.
Clinical History
Clinical History
Takotsubo cardiomyopathy was first described in Japan in the early 1990s. The name “Takotsubo” comes from the Japanese word for an octopus trap, as the left ventricle of the heart often takes on a distinctive shape resembling this trap during the condition. Patients often present with chest pain or discomfort, which can be severe and mimic a heart attack. Difficulty breathing is another common symptom patients experience.
The emotional stress that often precedes the condition can lead to feelings of anxiety or panic. Some individuals may experience nausea and vomiting. Takotsubo cardiomyopathy typically occurs suddenly and is often triggered by an emotionally or physically stressful event, such as the death of a loved one, a breakup, a severe illness, a motor vehicle accident, or surgery. It can also be associated with conditions like asthma attacks or seizures.
Physical Examination
Physical Examination
Takotsubo cardiomyopathy shares clinical similarities with acute coronary syndrome (ACS). This condition often arises in response to profound emotional or physical stressors, such as the unexpected loss of a family member, domestic strife, confrontations, a severe medical diagnosis, natural disasters, or financial setbacks. According to the International Takotsubo Registry study findings, the most prevalent symptoms include chest pain, breathlessness (dyspnea), and fainting (syncope).
Additionally, certain patients may exhibit signs and symptoms indicative of heart failure, rapid or slow heart rhythms (tachyarrhythmias and bradyarrhythmias), sudden cardiac arrest, or significant mitral valve leakage (severe mitral regurgitation). During a physical examination, healthcare providers might detect a systolic murmur with a late-peaking characteristic due to obstruction within the left ventricular outflow tract.
Furthermore, some individuals may display signs and symptoms resembling a transient ischemic attack or stroke-like presentation, primarily due to the formation of blood clots in the heart’s apex and subsequent embolization. It is important to note that roughly 10% of individuals with stress cardiomyopathy progress to cardiogenic shock.

Treatment Paradigm
The management of Takotsubo cardiomyopathy poses a challenge due to the absence of prospective randomized data, leading to a reliance on clinical experience and expert consensus. Given the initial similarity in presentation to acute coronary syndrome, the initial therapeutic approach involves several components, including aspirin, ACE inhibitors, beta-blockers, lipid-lowering medications, and coronary angiography to rule out obstructive coronary artery disease.
The choice of therapy depends on the patient’s clinical presentation and hemodynamic status. In stable patients, treatment typically includes cardioselective beta-blockers and ACE inhibitors for a relatively short duration, usually around 3 to 6 months. Serial imaging studies are crucial during this period to assess wall motion abnormalities and ventricular ejection fraction, helping to gauge the progression or improvement of the condition.
Anticoagulation is typically reserved for patients with documented ventricular thrombus formation or evidence of embolic events, which occurs in approximately 5% of individuals with Takotsubo cardiomyopathy. Inotropic agents may be required for patients with more unstable hemodynamics or those presenting in cardiogenic shock without left ventricular outflow obstruction.
In certain cases, mechanical hemodynamic support can be beneficial, utilizing devices such as an intra-aortic balloon pump or, in rare instances, left ventricular assist devices. In the presence of left ventricular outflow obstruction in cardiogenic shock, it is advisable to avoid inotropic agents. Instead, phenylephrine is the preferred pressor agent, often combined with beta-blocker agents.
