Trial summary

Coronary angioplasty is rather frequently performed in such situations, presumably because, changes in the atherosclerotic plaque under drug treatment, have remained poorly described so far. Read more about this study

About this study

Official title: Intravascular Ultrasound (IVUS) Assessment of the Atherosclerotic Plaque Causing an Acute Coronary Syndrome: One-year Changes Under Optimal Secondary Prevention Drug Treatment

Coronary angioplasty is rather frequently performed in such situations, presumably because, changes in the atherosclerotic plaque under drug treatment, have remained poorly described so far. Intravascular ultrasound (IVUS) enables a precise description of coronary atheroma, better than the one provided by coronary angiography.

Read the detailed description

According to current guidelines, patients with coronary lesions with stenosis <70% should receive optimal secondary prevention drug treatment without angioplasty, even after an acute coronary syndrome (ACS). Nevertheless, coronary angioplasty is rather frequently performed in such situations, presumably because, changes in the atherosclerotic plaque under drug treatment, have remained poorly described so far. Intravascular ultrasound (IVUS) enables a precise description of coronary atheroma, better than the one provided by coronary angiography.

The first objective is to assess by endo-coronary ultrasound, under optimal medical treatment, the evolution of atheromatous plaque (with stenosis <70%). The evolution will be appreciated after 12 months of treatment the percentage of atheromatous volume (PVA). The aim of the first secondary objective to evaluate, after 12 months of treatment, the evolution of the total atheromatous volume (VAT) and the standardized total atheromatous volume (standardized VAT). The Second secondary objective is to evaluate by endo-coronary ultrasound, the evolution of a stable atheromatous plaque. This analysis will be performed in patients with a second coronary lesion (atheroma plaque), resulting in less than 70% stenosis, and not being responsible for acute coronary syndrome. The evolution of the stable plate will be compared to the evolution of the unstable plate. Finally, the third secondary objective is to estimate the incidence of clinical events (death, acute coronary syndromes, ischemic stroke, revascularization, hospitalization for heart failure) within 12 months of the occurrence of an acute coronary syndrome managed by medical treatment optimal secondary prevention (without performing angioplasty).

What is being measured

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

  1. atheroma volume

    One-year changes in percent atheroma volume (PAV), measured in the lesion which has promoted the ACS (unstable plaque).

    Measured: one year

Secondary outcomes (4)
  1. PAV

    One-year changes total atheroma volume (TAV) and normalized TAV. One year changes in PAV, TAV and normalized TAV in a stable plaque (not involved in the ACS).

    Measured: 1 year

  2. incidence of the clinical cardiovascular events

    one year incidence of clinical cardiovascular events (death, acute coronary syndrome, ischaemic stroke, revascularization, hospitalization for heart failure).

    Measured: 1 year

  3. TAV

    One-year changes in PAV, TAV and normalized TAV, in a stable plaque (not involved in the ACS)

    Measured: 1 year

  4. normalized TAV

    One-year changes in PAV, TAV and normalized TAV, in a stable plaque (not involved in the ACS)

    Measured: 1 year

Questions about this trial

What is this clinical trial studying?

An observational study of Acute Coronary Syndrome, run by University Hospital, Toulouse at 3 sites 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 1 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 Jul 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites 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?

atheroma volume (time frame: one year). 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 Jul 2020.
