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 Any age
  • All sexes
  • No healthy volunteers
  • Child, Adult, Older adult

Study population: The samples of this study are from Peking University Third Hospital, Peking University First Hospital and Wuhan Asian Heart Hospital.

Who may be able to join

  • Myocardial infarction group: case group
  • This group includes acute myocardial infarction (ST segment elevation and non ST segment elevation) and old myocardial infarction. The diagnostic basis of acute myocardial infarction: cardiac biomarkers (cardiac troponin and / or myocardial enzymes) increased or decreased, at least once the value exceeded the upper limit of normal, and there was the following evidence of myocardial ischemia: (1) clinical symptoms of myocardial ischemia( 2) New changes of myocardial ischemia appeared in ECG, i.e. new ST segment changes or left bundle branch block( 3) Pathological Q wave appeared in ECG( 4) Imaging evidence showed new loss of myocardial viability or regional wall motion abnormalities. Diagnosis basis of old myocardial infarction: Patients with previous history of myocardial infarction and confirmed by Peking University Third Hospital, first hospital, Asian heart hospital and Taiyuan cardiovascular hospital.

  • (1) There was severe hepatic and renal insufficiency (2) Cancer and malignant disease patients (3) Severe acute infection or metabolic disorder (4) Acute attack of chronic heart failure (5) Acute myocardial infarction without revascularization within 2 weeks (6) Secondary to obvious valvular heart disease, hypertrophic obstructive heart disease

About this study

Official title: Peking University and University of Michigan- Study of Myocardial Infarction and Atherosclerosis

Coronary heart disease and myocardial infarction have become a major threat to the health of our people. Their incidence rate and mortality rate are still rising. Dyslipidemia is one of the important risk factors. However, little is known about the genetic information of myocardial infarction and dyslipidemia, especially in Chinese population. This project aims to identify new loci related to myocardial infarction and blood lipid level in Chinese population, compare these gene variations with 94 gene variations related to myocardial infarction and blood lipid level in European population, and extract gene variations related to myocardial infarction and blood lipid level in Chinese population. In this case-control study, 3998 blood samples and 702 new blood samples were collected from the sample bank of Peking University Third Hospital and first hospital, respectively. The blood samples were collected from Asian heart disease hospital, Taiyuan cardiovascular disease hospital, Beijing Third Hospital and Shijingshan community follow-up population According to the results of carotid ultrasound or treadmill exercise test, the samples were divided into myocardial infarction group and control group, and the corresponding blood lipid levels were collected. The samples were genotyped by the metabochip gene chip of Illumina company. The data were processed by the calling algorithm of BeadStudio Gentrain 1.0 and the GenoSNP software. The related genes of myocardial infarction were analyzed by logistic regression, and the related genes of blood lipid level were analyzed by linear regression.

Background: coronary heart disease and myocardial infarction have become a major disease threatening the health of our people. Their incidence rate and mortality rate are still rising. Dyslipidemia is one of the important risk factors. However, little is known about the genetic information of myocardial infarction and dyslipidemia, especially in Chinese population.

Objective: to identify new loci related to myocardial infarction and blood lipid level in Chinese population, compare these gene variations with 94 gene variations related to myocardial infarction and blood lipid level in European population, and extract gene variations related to myocardial infarction and blood lipid level in Chinese population.

Methods: This is a case-control study. 9498 blood samples and 702 new blood samples were collected from the sample bank of Peking University Third Hospital and first hospital respectively. The blood samples were collected from Asian heart disease hospital, Beijing Third Hospital and Shijingshan community follow-up population According to the results of carotid ultrasound or treadmill exercise test, the samples were divided into myocardial infarction group and control group, and the corresponding blood lipid levels were collected. The samples were genotyped by the metabochip gene chip of Illumina company. The data were processed by the calling algorithm of BeadStudio Gentrain 1.0 and the GenoSNP software. The related genes of myocardial infarction were analyzed by logistic regression, and the related genes of blood lipid level were analyzed by linear regression.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Single-nucleotide Polymorphism of genes related with DyslipidemiaGenetic

    This study is an observational study to study the effect of different genotypes on the incidence of myocardial infarction

Study groups in NCT04950699
Study groupRoleWhat they receive
ControlPatients without typical symptoms of coronary heart disease, and coronary angiography or coronary CT showed no significant stenosis (coronary stenosis less than 30%), they were non coronary heart disease group, namely control group.
Receives: Genetic: Single-nucleotide Polymorphism of genes related with Dyslipidemia
myocardial infarctionThis group includes acute myocardial infarction (ST segment elevation and non ST segment elevation) and old myocardial infarction. The diagnostic basis of acute myocardial infarction: cardiac biomarkers (cardiac troponin and / or myocardial enzymes) increased or decreased, at least once the value exceeded the upper limit of normal, and there was the following evidence of myocardial ischemia: (1) clinical symptoms of myocardial ischemia( 2) New changes of myocardial ischemia appeared in ECG, i.e. new ST segment changes or left bundle branch block( 3) Pathological Q wave appeared in ECG( 4) Imaging evidence showed new loss of myocardial viability or regional wall motion abnormalities. Diagnosis of old myocardial infarction: the patient provided a history of previous myocardial infarction and confirmed as old myocardial infarction by the third or First Hospital of Peking University.
Receives: Genetic: Single-nucleotide Polymorphism of genes related with Dyslipidemia

Questions about this trial

What is this clinical trial studying?

An observational study of Coronary Heart Disease, run by Peking University Third Hospital.

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 4 inclusion and 1 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 6 Jul 2021. Status can change between updates, so confirm with the study contact before making plans.

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?

myocardial infarction (time frame: Retrospective analysis of cases in 6 years before the start of the study). 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 6 Jul 2021.
