About this study

Official title: Effects of Guiding Catheter on Fractional Flow Reserve and Non-Hyperemic Pressure Ratios for the Assessment of Coronary Artery Stenoses - Disengage @Rest

The DISENGAGE@rest study is a prospective registry carried out at Federico II University of Naples with the aim to evaluate the influence of the guiding catheter engagement within the coronary ostium on both FFR and non-hyperaemic pressure ratios values (such as Pd/Pa and the Resting Full-cycle Ratio -RFR), as well as the corresponding clinical impact on decision-making strategies. Consecutive patients with at least one intermediate stenosis (40%-90% by visual estimation) in any of the 3 main coronary arteries will be included.

Questions about this trial

What is this clinical trial studying?

An observational study of Coronary Artery Disease, run by Federico II University at 1 site in Italy.

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 5 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 2024. 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 Italy. 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?

Differences between FFR before and after guiding catheter disengagement (time frame: 10 minutes). The study lists 2 primary outcomes in all. 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 NCT04975425, which also lists 17 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 2024.
