About this study

Official title: Prognosis and Integrative Assessment of Aortic Coarctation Patients in CHINA

This is a systemic research of Chinese aortic coarctation patients, aiming to determine risk factors and serial biomarkers of aortic coarctation in prognosis.

Read the detailed description

The goal is to determine how much the left ventricle remodeling pre-operation and how it changes in the following-up duration after surgery, so does in the blood pressure and heart function. Risk factors associated with complications and prognosis are investigated and analyzed. Identification of novel biomarkers is needed to help predicting the prognosis, such as the left ventricle anti-remodeling, heart function and blood pressure improvement, as well as the exercise tolerance post-operation. The findings of this study will help the investigators developping new tests to monitor affected patients and optimize the operation as well as the follow-up procedure.

Retrospective Cohort of Aortic CoarctationPatients diagnosed as aortic coarctation and undergone corrected procedures from 2002 to Feb 28th 2019 were recruited in Beijing Anzhen Hospital, recording the results of clinical lab and echocardiography.
Perspective Cohort of Aortic CoarctationPatients diagnosed as aortic coarctation and undergone corrected procedures after Mar. 1st 2019 will be recruited in Beijing Anzhen Hospital, recording the results of clinical lab and echocardiography.

What is being measured

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

  1. Change in left ventricular mass

    Left ventricular mass will be measured by 2D echocardiography. For the retrospective cohort, the data is collected from the cases' medical record, and during follow-up visit.

    Measured: Prior to primary treatment and during follow-up visit(one month to 20 years for retrospective cohort and one year for prospective cohort)

  2. Hypertension

    Both resting blood pressure and exercise-related blood pressure will be assessed for patients above 5 years old during the follow-up visit.

    Measured: one month to 20 years after primary treatment for retrospective cohort and one year after primary treatment for prospective cohort

Secondary outcomes (10)
  1. Left ventricular systolic function

    Left ventricular systolic function assessed by echocardiography

    Measured: one month to 20 years after primary treatment for retrospective cohort and one year after primary treatment for prospective cohort

  2. Left ventricular diastolic function

    Left ventricular diastolic function assessed by echocardiography (TDI)

    Measured: one month to 20 years after primary treatment for retrospective cohort and one year after primary treatment for prospective cohort

  3. Left ventricular systolic heart function of longitudinal myocardium

    Left ventricular systolic heart function of longitudinal myocardium assessed by echocardiography (M mode Doppler).

    Measured: one month to 20 years after primary treatment for retrospective cohort and one year after primary treatment for prospective cohort

  4. Exercise tolerance

    Six minutes walking distance will be recorded and analyzed to evaluate the exercise tolerance. Echocardiographic images will be obtained after six minutes walking to assess the reserve function of left ventricle. Blood pressure will also be taken immediately after the Six minutes walking to analyze exercise-induced hypertension.

    Measured: one month to 20 years after primary treatment for retrospective cohort and one year after primary treatment for prospective cohort

  5. Biomarkers of vascular inflammation

    Biomarkers of inflammation (hs-CRP). For the retrospective cohort, the data is collected from the cases' medical record, and during follow-up visit.

    Measured: Prior to primary treatment and during follow-up visit(one month to 20 years for retrospective cohort and one year for prospective cohort)

  6. Biomarkers of left ventricle remodeling

    Biomarkers of left ventricle remodeling (ST2)

    Measured: For the retrospective cohort, follow-up visit of 1 month to 20 years after primary treatment. For the prospective cohort, the data is collected prior to primary treatment and during follow-up visit of one year after primary treatment

  7. Biomarkers of left heart function

    Biomarkers of left heart function (BNP). For the retrospective cohort, the data is collected from the cases' medical record, and during follow-up visit.

    Measured: Prior to primary treatment and during follow-up visit(one month to 20 years for retrospective cohort and one year for prospective cohort)

  8. Biomarkers of hypertension phenotype related to aortic coarctation

    Biomarkers of hypertension phenotype related to aortic coarctation

    Measured: one month to 20 years after primary treatment for retrospective cohort and one year after primary treatment for prospective cohort

  9. Recoarctation

    Recoarctation assessed by echocardiography or computed tomography angiography.

    Measured: one month to 20 years after primary treatment for retrospective cohort and one year after primary treatment for prospective cohort

  10. All-cause death

    The data is collected during follow-up visit at follow-up time point.

    Measured: 20 years after primary treatment for retrospective cohort and one year after primary treatment for prospective cohort

Questions about this trial

What is this clinical trial studying?

An observational study of Coarctation of Aorta, run by Beijing Institute of Heart, Lung and Blood Vessel Diseases 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: status not confirmed, as of the sponsor's last update on 14 Jul 2020. 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?

Results are not available in the source record.

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

Contact Yuan WANG, PhD (86-010-64456169, wangyuan980510@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in left ventricular mass (time frame: Prior to primary treatment and during follow-up visit(one month to 20 years for retrospective cohort and one year for prospective cohort)). 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 14 Jul 2020; AzTrials last refreshed its copy on 8 Nov 2026.
