Tako-Tsubo cardiomyopathy

What it is

From: Orphanet

A rare cardiac disease characterized by acute occurrence of heart failure after an emotional or physical trigger; recovery of the wall motion abnormalities are observed within months. Symptoms are similar to acute coronary syndrome (ACS).

Reported clinical features and what the terms mean

The following findings are associated with this condition in Orphanet. They are not a checklist for diagnosing yourself, and they do not all occur in every affected person. Some are examination, imaging or laboratory findings that cannot be recognised at home.

The frequency labels describe how often a finding was reported among people with the condition in the source. They do not give the chance that a person with that symptom has the condition. Definitions below reproduce HPO terminology; they explain the term, not the likely severity in an individual.

Mildly reduced ejection fraction · Very frequent (99-80%)

A small reduction in the fraction of blood pumped from the left ventricle with each cardiac cycle. The normal range in adults is at least 50 percent, and a mild reduction is defined as 40-49 percent.

Chest pain · Frequent (79-30%)

An unpleasant sensation characterized by physical discomfort (such as pricking, throbbing, or aching) localized to the chest.

Increased circulating troponin T concentration · Frequent (79-30%)

An increased concentration of tropnin T in the blood, which is a cardiac regulatory protein that controls the calcium mediated interaction between actin and myosin. Raised cardiac troponin concentrations are now accepted as the standard biochemical marker for the diagnosis of myocardial infarction.

Reduced contraction of the left ventricular apex · Frequent (79-30%)

Reduced wall motion (contraction) of the apex of the left ventricle. This manifestation can be observed on echocardiography.

ST segment elevation · Frequent (79-30%)

An electrocardiographic anomaly in which the ST segment is observed to be located superior to the isoelectric line.

T-wave inversion · Frequent (79-30%)

An inversion of the T-wave (which is normally positive).

Abnormal B-type natriuretic peptide level · Occasional (29-5%)

A deviation from the normal circulating concentration of B-type natriuretic peptide (BNP).

Angina pectoris · Occasional (29-5%)

Paroxysmal chest pain that occurs with exertion or stress and is related to myocardial ischemia.

Decreased QRS voltage · Occasional (29-5%)

Reduced amplitude (height) of the QRS complex of the electrocardiogram (EKG), defined as amplitudes of all the QRS complexes in the limb leads are less than 5 mm or amplitudes of all the QRS complexes in the precordial leads less than 10 mm.

Dilatation of the ventricular cavity · Occasional (29-5%)

A localized outpouching of ventricular cavity that is generally associated with dyskinesia and paradoxical expansion during systole.

Dyspnea · Occasional (29-5%)

Difficult or labored breathing. Dyspnea is a subjective feeling only the patient can rate, e.g., on a Borg scale.

Hypertension · Occasional (29-5%)

The presence of chronic increased pressure in the systemic arterial system.

Hypotension · Occasional (29-5%)

Low Blood Pressure, vascular hypotension.

Left ventricular apical dyskinesis · Occasional (29-5%)

Dyskinesis is used to describe ventricular muscle segments that bulge outside the left ventricular cavity during systole, as opposed to contracting inwards with the rest of the segments.

Which doctor should you see?

The suggested department for discussing Tako-Tsubo cardiomyopathy is Cardiology, with a cardiologist as the relevant type of clinician. General physician / Family Medicine; paediatrician for children. Referral depends on symptoms.

This is an editorial referral starting point. The appropriate clinic depends on the person’s age, symptoms, previous diagnosis and local services. The first clinician can decide whether another specialty or a team is needed; a department label does not confirm the diagnosis.

How to prepare for an assessment

Bring a short timeline of the main symptoms: when they first appeared, whether they are constant or episodic, what seems to change them, and how they affect daily activities. Include previous reports, discharge summaries, current medicines and supplements, allergies, and any relevant family history. A dated record is more useful than trying to match every feature in an online article.

Ask the clinician what is already established and what remains uncertain. If a test is suggested, ask what question it answers, what its limitations are and how the result would change the next step. The information here is not an instruction to arrange every possible test. In children, bring growth, developmental and school information if it is relevant to the concern.

• Is the main concern heart structure, rhythm, circulation or another cause?
• Which symptoms should change the timing of follow-up?
• How would a proposed investigation change the care plan?

Treatment discussions and follow-up

The material gathered for this draft does not provide a complete condition-specific treatment pathway for Tako-Tsubo cardiomyopathy. That gap does not mean that treatment is unavailable. A clinician needs to establish the diagnosis and review current guidance before recommending medicines, procedures, rehabilitation or other support.

Before leaving the appointment, clarify the next review date, who will communicate results, and whom to contact if the situation changes. Discuss difficulties with sleep, work, school, mobility, eating or emotional wellbeing when these are relevant. Practical support may require coordination between the treating clinician and other services.

The collected references do not establish a complete prevention or long-term outlook section for this entry. Missing information should not be interpreted as proof that prevention is impossible or that a particular outcome is inevitable. Ask what is known for the exact subtype, stage and personal circumstances, and which uncertainties remain.

When to seek emergency help

Severe breathing difficulty, collapse, new stroke-like symptoms, a seizure that is prolonged or repeated without recovery, uncontrolled major bleeding, or an immediate risk of self-harm require emergency help. In India, call 112 or reach the nearest emergency department. This is a general, non-exhaustive warning list; it is not a condition-specific triage tool.
