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 21 to 99 years
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Study population: The patient population of interest and the main inclusion criterion for inclusion is the occurrence of chest pain (or anginal equivalent) in a patient without known significant CAD or a history of prior myocardial infarction, and the utilization of Corus CAD (Age/Sex/Gene Expression score - ASGES). Additionally, subjects with similar chest pain (or angina equivalent) whom did not undergo Corus CAD (ASGES) will be included as a control group, to understand the diagnostic evaluation and management of patients prior to Corus CAD (ASGES) use.

Who may be able to join

  • Symptoms suggestive of CAD, according to the opinion of the site clinician
  • Age >= 21 years

Who cannot join

  • History of myocardial infarction (MI)
  • History of high risk unstable angina, systemic infections or systemic inflammatory conditions
  • Current MI or acute coronary syndrome
  • Current New York Heart Association (NYHA) class III or IV congestive heart failure symptoms
  • Known/documented CAD
  • History/current Diabetes Mellitus
  • Taking steroids, immunosuppressive agents, or chemotherapeutic agents, at time of chest pain presentation

About this study

The purpose of this study is to understand the use of Corus CAD also known as Age/Sex/Gene Expression score (ASGES) in the clinical decision making process of patients who underwent the evaluation of chest pain or anginal equivalent symptoms. Specifically, to better understand whether the use of the assay in clinical decision making resulted in changes in noninvasive diagnostic test ordering or diagnostic yield of additional tests ordered and/or invasive angiography.

Read the detailed description

The UCU-CARD (Understanding Clinician Utility-Cardiology) study is a retrospective, matched-cohort evaluation of diagnostic testing in a community-based cardiology practice setting that used a personalized age, sex, and gene expression test during early work-up of patients with symptoms suggestive of obstructive CAD (http://www.clinicaltrials.gov, NCT02223286). The study measured the rates of advanced cardiac diagnostic testing after initial work-up, including stress testing with imaging, CTA, or ICA. Rates of advanced diagnostic testing for patients who received the age, sex, and gene expression test (ASGES) were compared with testing rates for matched historical controls (usual care). The study hypothesis was that incorporating the age, sex, and gene expression testing early in the diagnostic work-up pathway would permit the identification of patients for whom advanced diagnostic testing was not required, thereby avoiding unnecessary testing and enabling cardiologists to focus their diagnostic resources more efficiently.

This single-center study was conducted at the North Phoenix Heart Center (Phoenix, AZ), a community-based group cardiology practice that receives patients on referral from primary care physicians and other specialists in the surrounding area. The practice incorporated age, sex, and gene expression testing into its diagnostic protocol beginning in June 2011. Data collection was completed in December 2013. Institutional Review Board (IRB) approval of the study protocol was granted by Quorum Review. Informed consent waivers were granted as data collection was retrospective and all data were de-identified.

Study groupRoleWhat they receive
ASGES (Treatment Group)Patients who received a Corus CAD or Age/Sex/Gene Expression Score (ASGES) to aid in the diagnosis of obstructive CAD
Receives: Diagnostic Test: Corus CAD
Non-ASGES (Control Group)Patients who underwent usual care testing and did not receive a Corus CAD or Age/SEX/Gene Expression Score (ASGES) to aid in the diagnosis of obstructive CAD

What is being measured

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

  1. The primary measure of this study is the number of advanced diagnostic tests in ASGES (treatment group) patients compared to the number of advanced diagnostic tests in non-ASGES (control group) patients.

    The primary study endpoint was the percentage of patients for whom advanced diagnostic testing was ordered-stress testing with imaging, computed tomography angiography, or invasive coronary angiography.

    Measured: up to 24 months

Questions about this trial

What is this clinical trial studying?

An observational study of Coronary Artery Disease and Angina Pectoris, run by CardioDx at 3 sites in United States.

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 7 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 22 Feb 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in United States. 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?

The primary measure of this study is the number of advanced diagnostic tests in ASGES (treatment group) patients compared to the number of advanced diagnostic tests in non-ASGES (control group) patients. (time frame: up to 24 months). 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 22 Feb 2018.
