Trial summary

Myocardial perfusion scintigraphy is to evaluate coronary perfusion as well as heart muscle function. This examination takes place in two stages, one imaging at rest and one after a cardiac stress caused. This stress can be triggered as a first-line stress test. Read more about this study

About this study

Official title: Descriptive Study Comparing Regadenoson Versus Dipyridamole in Use as Pharmacological Stress Agent Before a Myocardial Perfusion Imaging by Single Photon Emission Computed Tomography (SPECT)

Myocardial perfusion scintigraphy is to evaluate coronary perfusion as well as heart muscle function. This examination takes place in two stages, one imaging at rest and one after a cardiac stress caused. This stress can be triggered as a first-line stress test. A pharmacological stress is proposed when stress test is not possible or contraindicated, Several drugs have a marketing authorization in this indication (adenosine, dipyridamole, regadenoson, dobutamine).

Among them, the regadenoson is the most recent molecule. Marketed in France since 2013, it would allow a reduction of undesirable effects compared to other agents, especially adenosine. It is simple and quick to use thanks to a single dose administration. However, its cost is nearly 30 times higher than dipyridamole. In the investigational center, dipyridamole is currently the first-line pharmacological stress agent, whereas regadenoson is reserved for a limited number of doses, the indication of which must be justified (asthmatic patient or with severe COPD). Few studies in the literature specifically compare these two pharmacological agents (examination time, cost, tolerance) and the opinion on the use of regadenoson in the service is limited.

Being tested
collect examination time, functional and clinical tolerability

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • collect examination time, functional and clinical tolerabilityOther

    Examination time : time from patient setup and launch of the pre-test to the end of the patient monitoring Functional tolerability : functional assessed by the patient Clinical tolerability : clinical score by the cardiologist

Study groups in NCT03084562
Study groupRoleWhat they receive
Dipyridamolestress test impossible or contraindicated (first intention)
Receives: Other: collect examination time, functional and clinical tolerability
Regadenosonstress test and dipyridamole impossible or contraindicated. In particular, patients with severe COPD or asthmatic patient. (second intention)
Receives: Other: collect examination time, functional and clinical tolerability

What is being measured

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

  1. Duration of the test

    Evaluate the time savings from the use of regadenoson versus dipyridamole by comparing the duration of the test.

    Measured: 24 hours (Visit 1: During the examen)

Questions about this trial

What is this clinical trial studying?

An observational study of Myocardial Perfusion Imaging, run by Hospices Civils de Lyon at 1 site in France.

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 5 inclusion and 2 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 13 Apr 2018. 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 France. 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?

Duration of the test (time frame: 24 hours (Visit 1: During the examen)). 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 13 Apr 2018.
