About this study

Official title: Comparison of the Diagnostic Performances of 82Rubidium Positron Emission Tomography and Conventional Scintigraphy With CZT Cameras for Detection of Myocardial Ischemia in a Population of Overweighed Patients and Women

The main objective of this study will be to compare the diagnostic performances of 82Rubidium-PET associated to pharmacologic stress (Persantine) to 99mTc-Sestamibi-SPECT with CZT cameras associated to a stress test (exercise, pharmacological, mixed) for detection of myocardial ischemia in a population of overweighed patients on one hand, and women on the other hand, in a population with an intermediate prevalence of coronary artery disease (≥ 3 cardiovascular risk factors in asymptomatic patients or prevalence of CAD ≥ 30 % using the DIAMOND-FORRESTER score in symptomatic patients).

Read the detailed description

The main objective of this study will be to compare the diagnostic performances of 82Rubidium-PET associated to pharmacologic stress (Persantine) to 99mTc-Sestamibi-SPECT with CZT cameras associated to a stress test (exercise, pharmacological, mixed) for detection of myocardial ischemia in a population of overweighed patients on one hand, and women on the other hand, in a population with an intermediate prevalence of coronary artery disease (≥ 3 cardiovascular risk factors in asymptomatic patients or prevalence of CAD ≥ 30 % using the DIAMOND-FORRESTER score in symptomatic patients).

Secondary objectives. (1) Comparison between the size and intensity of myocardial ischemia quantified using the sum difference score, left ventricular function at stress and at rest, measured with 99mTc-Sestamibi-SPECT with CZT cameras and 82Rubidium-PET.

(2) Comparison between the values of coronary fractional flow reserve measured invasively and noninvasively with 82Rubidium-PET in patients with stenosis ≥ 50 % on coronary angiography.

(3) Comparison of the effective dose caused by radiation exposure with 99mTc-Sestamibi-SPECT with CZT cameras and 82Rubidium-PET.

(4) Comparison of the costs of the two diagnostic strategies in this population of patients.

Inclusion criteria: Overweighed (body mass index ≥ 25) or women addressed in the Department of Nuclear Medicine for diagnostic cardiac scintigraphy with an intermediate pre-test prevalence of CAD (≥ 3 cardiovascular risk factors in asymptomatic patients or prevalence of CAD ≥ 30 % using the DIAMOND-FORRESTER score in symptomatic patients).

Non-inclusion criteria: Pregnant women; contraindication to dipyridamole injection.

Number of patients: 310 patients

Duration of the study. Duration of the study for a patient will be 16 months and 28 months for the first patients. Total duration of the study will be 40 months, including an 24-month inclusion time period.

Primary endpoint: Patients will be classified as positive in case of:

  • Myocardial ischemia defined as the presence of coronary stenosis ≥ 50 % on coronary angiography with functional impairment of blood flow confirmed by invasive measurement of coronary flow reserve (fractional flow reserve, FFR < 0.8), or, in absence of measurement of FFR, a critical coronary stenosis confirmed by the validation committee of coronary angiographies.
  • In absence of coronary angiography, the presence of cardiovascular event (cardiovascular or unknown cause of death, admission for acute coronary syndrome, unstable angina, myocardial ischemia or coronary revascularization) validated by the endpoint adjudication committee in the year following inclusion of the patient in the study.

Secondary endpoints: (1) Size and intensity of myocardial ischemia quantified using the sum difference score and, left ventricular function at stress and at rest, measured with 99mTc-Sestamibi-SPECT with CZT cameras and 82Rubidium-PET. (2) Values of coronary fractional flow reserve measured invasively and noninvasively with 82Rubidium-PET in patients with stenosis ≥ 50 % on coronary angiography. (3) Effective dose caused by radiation exposure with 99mTc-Sestamibi-SPECT with CZT cameras and 82Rubidium-PET. (4) Costs of the two diagnostic strategies in this population of patients.

What is being measured

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

  1. Myocardial ischemia

    Patients will be classified as positive in case of:

    • In absence of coronary angiography, presence of cardiovascular event during the following year.

    Measured: 1 year

Questions about this trial

What is this clinical trial studying?

A study testing Rubidium PET in people with Myocardial Ischemia, run by Assistance Publique - Hôpitaux de Paris 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 1 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 23 Feb 2017. 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?

Myocardial ischemia (time frame: 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01679886, which also lists 2 linked publications.

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 23 Feb 2017.
