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 18 to 75 years
  • All sexes
  • Healthy volunteers accepted
  • Adult, Older adult

Study population: The cases were all hospitalized patients recruited from two medical centers in Beijing and Harbin. The participants with two or more risk factors of CAD (age>45 for man and >55 for woman, hypertension, diabetes, overweight, hyperlipidemia) were subjected to treadmill stress test and selected as controls if their ECG were normal without clinical symptoms.

Who may be able to join

  • The coronary artery disease was defined by one of the following criteria-(1) based on World Health Organization criteria in terms of elevations of cardiac enzymes, electrocardiography (ECG) and clinical symptoms (angina, chest pressure, or shortness of breath); (2) angiographic evidence of more than 50% stenosis in one or more major coronary arteries; (3) previous history of PCI (percutaneous coronary intervention) or CABG (coronary artery bypass graft).
  • The controls were selected from the two medical centers meeting the following criteria: (1) with no family history for CAD; (2) no clinical symptoms for CAD; (3) resting ECG showed normal results. The subjects with two or more risk factors of CAD (age>45 for man and >55 for woman, hypertension, diabetes, overweight, hyperlipidemia) were subjected to treadmill stress test and selected as controls if their ECG were normal without clinical symptoms.

Who cannot join

  • Those with history of cardiomyopathy, valvular disease, peripheral vascular disease, stroke, severe hepatic and kidney deficiency were excluded in our study.

About this study

The cases were hospitalized patients from two medical centers in Beijing and Harbin respectively. Venous blood was collected by standard vein puncture in fasting condition.

Read the detailed description

In our study, the CAD was defined by one of the following criteria: (1) based on World Health Organization criteria in terms of elevations of cardiac enzymes, electrocardiography (ECG) and clinical symptoms (angina, chest pressure, or shortness of breath); (2) angiographic evidence of more than 50% stenosis in one or more major coronary arteries; (3) previous history of PCI (percutaneous coronary intervention) or CABG (coronary artery bypass graft). The controls were selected from the two medical centers meeting the following criteria: (1) with no family history for CAD; (2) no clinical symptoms for CAD; (3) resting ECG showed normal results. The subjects with two or more risk factors of CAD (age>45 for man and >55 for woman, hypertension, diabetes, overweight, hyperlipidemia) were subjected to treadmill stress test and selected as controls if their ECG were normal without clinical symptoms. Those with history of cardiomyopathy, valvular disease, peripheral vascular disease, stroke, severe hepatic and kidney deficiency were excluded in our study.

Venous blood was collected by standard vein puncture in fasting condition. Four single-nucleotide polymorphisms (SNPs) (rs7586970, rs6434222, rs10153820 and rs8176528) were detected with polymerase chain reaction-direct sequencing method. And the genotypes of these SNPs were determined in both CAD patients and non-CAD controls.

Questions about this trial

What is this clinical trial studying?

An observational study of Coronary Heart Disease, run by Chinese PLA General 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 2 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: status not confirmed, as of the sponsor's last update on 10 Nov 2016. 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?

Results are not available in the source record.

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

Contact Yundai Chen, Ph D (+86 531-51666045, ydchen301@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

the frequencies of TFPI were associated with CAD in Han Chinese (time frame: 1 year). 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 10 Nov 2016.
