About this study

Official title: Research of Intracardiac Hemodynamics and Myocardial Strains of Athlete's Heart

The goal of this observational study is to compare the differences of intracardiac hemodynamics and myocardial strain in athletes with different training levels to adapt to long-term high-level training in rest conditions. The main questions aim to answer are: 1. whether an increase in amplitude and duration of intracardiac hemodynamics and myocardial strain compared with healthy controls; 2. Whether significant correlations exist between the hemodynamic indices and training level.

Participants will be asked to filling out the questionnaire, such as the age, training year (the number of years the athlete has participated in any sport), technical hierarchy (promoted by the Competitive Sports Department of the General Administration of Sport of China, weekly training time in the last 6 months, height, weight, body surface area, heart rate, systolic blood pressure, and diastolic blood pressure; and will be asked to perform an examination of transthoracic echocardiography.

Researchers will compare differences of cardiac structure and function, especially the hemodynamics and myocardial strain to see if training level could affect the cardiac function through hemodynamics and myocardial strain.

What is being measured

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

  1. intracardiac hemodynamics in mmHg/mm using vector flow mapping

    intraventricular pressure gradient from left ventricular apex to base

    Measured: through study completion, an average of 1 year

  2. myocardial strain in % using two-dimension tissue tracking

    left ventricular longitudinal strain

    Measured: through study completion, an average of 1 year

Secondary outcomes (1)
  1. wall shear stress in pascal using vector flow mapping

    segmental wall shear stress of the left ventricle

    Measured: through study completion, an average of 1 year

Questions about this trial

What is this clinical trial studying?

An observational study of Cardiac Structure and Function and Intracardiac Hemodynamic, run by Chengdu Sport University at 1 site in China.

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 2 inclusion and 2 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 30 Jul 2024. 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 China. 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?

intracardiac hemodynamics in mmHg/mm using vector flow mapping (time frame: through study completion, an average of 1 year). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 30 Jul 2024.
