Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Study population: Individuals with manifest Takotsubo cardiomyopathy

Inclusion criteria: Mayo Clinic Diagnostic Criteria (Prasad et al. American Heart Journal 2008)

  1. Transient hypokinesis, akinesis, or dyskinesis of the left ventricular mid segments with or without apical involvement; the regional wall motion abnormalities extend beyond a single epicardial vascular distribution; a stressful trigger is often, but not always present.*
  2. Absence of obstructive coronary disease or angiographic evidence of acute plaque rupture. †
  3. New electrocardiographic abnormalities (either ST-segment elevation and/or T-wave inversion) or modest elevation in cardiac troponin.

In both of the above circumstances, the diagnosis of TTC should be made with caution, and a clear stressful precipitating trigger must be sought. * There are rare exceptions to these criteria such as those patients in whom the regional wall motion abnormality is limited to a single coronary territory.

† It is possible that a patient with obstructive coronary atherosclerosis may also develop TTC.

Exclusion criteria: Patients with Myocarditis

About this study

Official title: International Multicenter Registry on Takotsubo Cardiomyopathy

This is a multicenter, multinational, prospective and retrospective, observational study of patients with Takotsubo cardiomyopathy (TTC).

Data on natural profile (demographical characteristics, clinical phenotype, laboratory values, electrocardiography parameters, echocardiography parameters, coronary angiography parameters, medication) and outcome are systematically collected.

Our aim is to gain a better insight into the clinical profile and pathophysiology of TTC.

Read the detailed description

Registry is an open-ended study and eligible individuals are assessed at index event and follow-up on their phenotypical characteristics. Furthermore, outcome data are collected (by clinical visits or telephone follow-up).

In addition, participants are given the option to consent to the donation of biosamples for the purposes to identify TTC specific biomarkers and mutations (sub-study on behalf of the registry).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Natural history of TTC

    To determine the natural history of Takotsubo cardiomyopathy.

    Measured: 10 years

Secondary outcomes (1)

  1. Cardiovascular complications, recurrence of TTC and all cause mortality

    Patients will be assessed for cardiovascular complications during hospitalisation and at follow-up (up to 10 years)

    Measured: at hospitalizsation, short term (1 year) and long term (10 years)

Questions about this trial

What is this clinical trial studying?

An observational study of Takotsubo Cardiomyopathy, run by University of Zurich at 1 site in Switzerland.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 21 May 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Switzerland. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Christian Templin, MD, PhD (+41 44 255 95 85, christian.templin@usz.ch), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Natural history of TTC (time frame: 10 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01947621, which also lists 18 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 May 2014.
