About this study

Official title: Dual-Source CT and STress Cardiac Magnetic Resonance Assessment in the Triage of Patients With Suspected Acute Coronary Syndromes (D-STAT)

This study is designed to evaluate the effectiveness and measurable cost impact of stress cardiac MRI for non-invasive evaluation of intermediate lesions discovered on CCTA in low-to-intermediate risk patients admitted to the ED with suspected ACS. Our primary objective is to determine if the strategy of CTA + stress CMR will reduce the length of time in the ED required to establish a definitive diagnosis, compared to CTA + stress MPI.

Read the detailed description

Non-invasive evaluation of coronary anatomy via multi-slice computed tomography with coronary CT angiography (CCTA) has been shown to provide rapid and accurate non-invasive coronary angiography. Although CCTA can be rapidly and safely performed and despite improving our ability to image coronary arteries in this noninvasive fashion, the limitation of CCTA is lack of physiological information in intermediate lesions, i.e., if a patient has a blockage of 40-60% on CCTA in an artery, it is not possible to know if this is what causes symptoms in a patient. This limitation is currently being overcome by stress testing, commonly with perfusion imaging (nuclear stress test). However, disadvantages of nuclear stress testing include long testing times (usually > 4 hours) and use of radiation. Patients with intermediate/uninterpretable lesions on CCTA will be randomized to MPI or MRI.

The endpoints of the study are:

Primary outcome variables:

  1. Length of ED stay until definitive diagnosis (time from ED triage until definitive diagnosis).

Secondary outcome variables will include:

  1. Cost of care of an early diagnostic strategy utilizing stress CMR vs. standard care (costs incurred during index hospitalization and 30 day follow up period) in patients with intermediate lesions of CTA.
  2. Accuracy of CTA + stress CMR in prediction of occurrence of major adverse cardiac events (MACE) during a 3 month follow-up period, compared to the standard care (CTA + stress/rest MPI): cardiac death, acute myocardial infarction, need for coronary artery revascularization, need for admission or treatment for documented CAD.

Questions about this trial

What is this clinical trial studying?

An observational study of Coronary Disease, run by Corewell Health East 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 4 inclusion and 18 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: stopped early, as of the sponsor's last update on 1 Mar 2010. 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 was stopped early (reason given: Lack of staff and funding.). Results are not available in the source record.

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.

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 1 Mar 2010.
