About this study

The purpose of the study is to investigate the potential correlations of global longitudinal strain and peak left atrial strain, measured by speckle tracking echocardiography with the severity of hypertrophic cardiomyopathy and the risk for arrhythmias.

Specifically the investigational questions are:

  1. Is there a correlation between myocardial deformation parameters of the left heart chambers with other important ultrasound parameters (eg maximal wall thickness, presence of subaortic obstruction, etc.) in patients with hypertrophic cardiomyopathy?
  2. Is there a correlation between myocardial deformation parameters of the left heart chambers and the symptomatology or functional capacity of patients with hypertrophic cardiomyopathy?
  3. Is there a correlation between the myocardial deformation parameters of the left heart chambers and the exercise capacity, as evidenced by the cardiopulmonary exercise test, in patients with hypertrophic cardiomyopathy?
  4. Is there a correlation between myocardial deformation parameters of the left heart chambers with the risk of ventricular or supraventricular arrhythmias in patients with hypertrophic cardiomyopathy?
  5. Is there a correlation between myocardial deformation parameters of the left heart chambers and risk factors for sudden death?
Read the detailed description

Myocardial deformation parameters of the left heart chambers are of particular clinical importance because of their possible association with the severity of HCM and the presence of arrhythmias. However,current literature appears conflicting.

This is a prospective cohort study aiming to examine the echocardiographic parameters of myocardial deformation, estimated by the "speckle tracking" method, and their correlation with clinical presentation and symptomatology, other imaging parameters, exercise capacity, arrhythmias (ventricular or supraventricular) and risk factors for sudden death in patients with hypertrophic cardiomyopathy.

Although, similar efforts have been made in international literature, they are scarce and their results contradictory. The present study is the first to be performed in a Greek population, a fact that is particularly important given the genetic heterogeneity of the disease.

Questions about this trial

What is this clinical trial studying?

An observational study of Hypertrophic Cardiomyopathy, run by AHEPA University Hospital at 1 site in Greece.

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

Who may be eligible to take part?

The sponsor lists 1 inclusion and 3 exclusion criteria. 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: finished, as of the sponsor's last update on 20 Jul 2022. 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 Greece. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Cardiac arrest (time frame: 3 years). The study lists 4 primary outcomes in all. 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 NCT04112511, which also lists 2 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 20 Jul 2022.
