Study population: Non-diabetic subjects will be enrolled at the Department of Cardiology, Mayo Clinic, Florida. Enrollment will not be randomized. Subjects will be enrolled based on achieving an equal number of men and women, and known Coronary Artery Disease or CAD (prior history of ischemia by stress test or a coronary catheterization documenting greater than or equal to 50% stenosis in any vessels within 12 months prior to enrollment) and no known CAD (controls - prior of history of coronary catheterization documenting less than or equal to 15% stenosis in any vessels within 12 months prior to enrollment). Enrollment will be stratified as shown below:

About this study
Official title: Effect of Exercise Stress Testing on Peripheral Gene Expression Using Corus CAD Diagnostic Test (Age, Sex, Gene Expression Score ASGES).
This is a prospective, single-center study that aims to evaluate the acute and delayed effect of exercise stress testing on the peripheral gene expression (PGE) levels using a predefined gene set established in the Corus CAD (Age/Sex/Gene Expression score - ASGES) test in subject with known obstructive coronary artery disease (CAD) and in control subjects (without known CAD).
Read the detailed description
This is a prospective, single-center study. This protocol is a pilot study to investigate the effects of "acute" exercise (by exercise stress testing; modified Bruce protocol) on peripheral gene expression (PGE) levels as measured by Corus CAD score (Age/Sex/Gene Expression score - ASGES). Subjects will have blood sampling at baseline, at peak exercise, within 30 to 60 minutes post-exercise, at 24-36 hours post-exercise. The study will be stratified by presence of CAD and gender. An equal number of subjects with known CAD and normal controls will be enrolled. Equally, an equal number of men and women will be included. A screening CBC and HgbA1c will be performed to ensure the subject meets the intended use instruction for Corus CAD (ASGES). Data collection will include presence or absence of ECG ischemia with testing, as well as heart rate and blood pressure response to exercise with other ECG and dynamic variables. There will be four blood samples taken per subject as shown in the figure below.

Questions about this trial
What is this clinical trial studying?
An observational study of Coronary Artery Disease and Angina Pectoris, run by CardioDx at 1 site 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 3 inclusion and 15 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 31 Jan 2019. 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 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?
Age/Sex/Gene expression score (ASGES) difference between peak exercise and baseline (time frame: up to 1 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 31 Jan 2019.
