July 13, 2021 updated by: Xie Mingxing

Union Hospital, Tongji Medical College, Huazhong University of Science and Technology

The aims of this study are to 1. Assess the preoperative and postoperative atrial and ventricular structure and function comprehensively in heart transplantation; 2. Explore the early, accurately and non-invasively indicators for evaluating myocardial fibrosis in end-stage heart failure, as well detecting acute rejection (AR),coronary allograft vasculopathy(CAV) and adverse clinical events in heart transplant patients by using conventional and the advanced echocardiography.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

This study will enrolled 1000 HT patients and 500 healthy controls, and the cardiac structure and function will be evaluated by ultrasound multimodal imaging. And the study aimed to 1. Assess the preoperative and postoperative atrial and ventricular structure and function comprehensively in heart transplantation; 2. Explore the early, accurately and non-invasively indicators for evaluating myocardial fibrosis in end-stage heart failure, as well detecting acute rejection(AR),coronary allograft vasculopathy(CAV) and adverse clinical events in heart transplant patients by using conventional and the advanced echocardiography.

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Observational

Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
1500

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

20 years to 100 years (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
HT group
Patients have echocardiography examination before and after heart transplantation.
Control group
healthy volunteers who had no history of hypertension, diabetes mellitus, renal failure or other organic diseases based on physical examinations, biochemical tests, electrocardiogram, echocardiography were enrolled as control group

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Using Image-Pro Plus 6.0 software to measure myocardial fibrosis
Time Frame: the measurement of myocardial fibrosis up to 1 year after heart transplant
The extent of myocardial fibrosis of the myocardial tissue from the removed heart during heart transplant was measured by Image-Pro Plus 6.0 software up to 1 year after heart transplant
the measurement of myocardial fibrosis up to 1 year after heart transplant
All cause death after the inclusion of the study
Time Frame: All cause death happened after inclusion of this study, up to 5 years
All cause death after HT was obtained via telephone interview with family members; contact with his/her physicians; or hospital records every year
All cause death happened after inclusion of this study, up to 5 years
Acute rejection after the inclusion of the study
Time Frame: Acute rejection happened after inclusion of this study, up to 5 years
Acute rejection after the inclusion of the study was obtained at regular intervals via telephone interview with the patient, or if deceased, with family members; contact with his/her physicians; or hospital records every year
Acute rejection happened after inclusion of this study, up to 5 years
Cardiac allograft vasculopathy after the inclusion of the study
Time Frame: Cardiac allograft vasculopathy happened after inclusion of this study, up to 5 years
Cardiac allograft vasculopathy after the inclusion of the study was obtained at regular intervals via telephone interview with the patient, or if deceased, with family members; contact with his/her physicians; or hospital records every year
Cardiac allograft vasculopathy happened after inclusion of this study, up to 5 years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Major adverse cardiac events after the inclusion of the study
Time Frame: Major adverse cardiac events happened after inclusion of this study，up to 5 years
Major adverse cardiac events after the inclusion of the study was obtained at regular intervals via telephone interview with the patient, or if deceased, with family members; contact with his/her physicians; or hospital records every year
Major adverse cardiac events happened after inclusion of this study，up to 5 years

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (ANTICIPATED)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
August 1, 2021

Primary Completion (ANTICIPATED)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
