About this study

Official title: Quantitative Analysis of Functional Computed Tomography (CT) Imaging of Coronary Atherosclerosis

The purpose of this prospective observational study is to evaluate the diagnostic and prognostic performance of a "one-stop" comprehensive coronary artery anatomy and function assessment for CAD.

Read the detailed description

Coronary CT angiography (CCTA) has become a reliable diagnostic technique to evaluate coronary artery disease (CAD) with high sensitivity and a negative predictive value. However, CCTA provides only anatomic information and tends to overestimate stenosis severity and is limited in its ability to diagnose myocardial ischemia. Undertaking additional CT myocardial perfusion imaging(CT-MPI) and CT-FFR improves specificity and positive predictive value, reducing unnecessary invasive coronary angiography. The purpose of this prospective observational study is to evaluate the diagnostic and prognostic performance of a "one-stop" comprehensive coronary artery anatomy and function assessment for CAD. SPECT myocardial perfusion imaging (SPECT-MPI)and invasively measured fractional flow reserve (FFR) will serve as the reference standard.

What is being measured

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

  1. Major Adverse Cardiovascular Events

    including cardiac death, all-cause death, acute coronary syndrome, readmission for acute coronary syndrome or heart failure, and Revascularization.

    Measured: 5 years

Secondary outcomes (4)
  1. Diagnostic performance of CT-MPI

    Diagnostic accuracy, Sensitivity, specificity, negative predictive value(NPV) and positive predictive value(PPV) of CT-perfusion imaging (quantitative and qualitative analysis) to determine the presence/absence of significant coronary artery disease at the subject level when compared with invasive FFR and SPECT-MPI.

    Measured: From admission to discharge, up to 1 week

  2. Diagnostic performance of CT-FFR

    Diagnostic accuracy, Sensitivity, specificity, negative predictive value(NPV) and positive predictive value(PPV) of CT-FFR to determine the presence/absence of significant coronary artery disease at the subject level when compared with invasive FFR and SPECT-MPI.

    Measured: From admission to discharge, up to 1 week

  3. Diagnostic performance of CT-MPI

    Diagnostic accuracy, Sensitivity, specificity, negative predictive value(NPV) and positive predictive value(PPV) of CT-perfusion imaging (quantitative and qualitative analysis) to determine the presence/absence of significant coronary artery disease in per-vessel level when compared with invasive FFR and SPECT-MPI.

    Measured: From admission to discharge, up to 1 week

  4. Diagnostic performance of CT-FFR

    Diagnostic accuracy, Sensitivity, specificity, negative predictive value(NPV) and positive predictive value(PPV) of CT-FFR to determine the presence/absence of significant coronary artery disease in per-vessel level when compared with invasive FFR and SPECT-MPI.

    Measured: From admission to discharge, up to 1 week

Questions about this trial

What is this clinical trial studying?

An observational study of Coronary Artery Disease, run by Qilu Hospital of Shandong 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 3 inclusion and 12 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 2 Aug 2021. 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?

Major Adverse Cardiovascular Events (time frame: 5 years). 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 2 Aug 2021; AzTrials last refreshed its copy on 7 Nov 2026.
