Study Comparing CT Scan and Stress Test in Diagnosing Coronary Artery Disease in Patients Hospitalized for Chest Pain (PROSPECT)

August 21, 2015 updated by: Jeffrey Levsky, Montefiore Medical Center

A Randomized Trial Comparing Multi-Detector Coronary CT Angiography and Stress Myocardial Perfusion Imaging as the Initial Test for the Diagnosis of Coronary Artery Disease in Intermediate Risk Patients Admitted for Chest Pain

The purpose of this study is to determine whether coronary artery CT scanning or nuclear stress testing is better at diagnosing chest pain patients with coronary artery disease to select appropriate candidates for coronary catheterization and re-vascularization.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
400

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

21 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • patient admitted for chest pain or pressure
  • patient at intermediate short term risk of MI or death (AHA/ACC guidelines)

Exclusion Criteria:

  • prior diagnosis of coronary artery disease
  • evidence of ongoing myocardial infarction (and other high risk criteria per AHA/ACC guidelines)
  • contraindications to EKG-gated CT scanning with iodinated intravenous contrast under beta-blockade

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: CTA
Initial EKG-gated computed tomography angiography of the coronary arteries
Procedure: Coronary Computed Tomography Angiography
64-detector, retrospectively EKG-gated, computed tomography angiography of the coronary arteries during heart rate control (intravenous metoprolol, when necessary)
Other Names:
  • CCTA
  • Coronary CTA
  • Coronary CT
  • Coronary Artery CT
  • Coronary Artery CTA
  • Coronary CT Angiography
  • CTA of the Coronary Arteries
Active Comparator: MPI
Initial nuclear stress myocardial perfusion imaging
Procedure: Stress Nuclear Myocardial Perfusion Imaging
Usually dual-isotope perfusion imaging at rest (201-Thallium) and at stress (99m-Technetium-MIBI). Some patients will have a 2-day MIBI protocol. Gated SPECT and attenuation-correction images will be obtained. Treadmill stress will be performed. If a patient is unable to exercise, adenosine or dobutamine will be given.
Other Names:
  • stress test
  • sestamibi
  • nuclear stress test
  • nuclear cardiology
  • nuclear perfusion imaging
  • dual-isotope stress test
  • thallium
  • myocardial perfusion imaging
  • gated SPECT

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Coronary catheterization that does not lead to re-vascularization
Time Frame: 1 year
1 year

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Length of Hospital Stay (time to discharge)
Time Frame: usually from hours to a few days (average about one day)
usually from hours to a few days (average about one day)
Non-fatal myocardial infarction
Time Frame: 1 year
1 year
Death (all cause)
Time Frame: 1 year
1 year
Post-test renal dysfunction
Time Frame: usually within a few days
usually within a few days

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit).
