About this study

The investigators will study Radial artery injury and endothelial function following trans-radial cardiac catheterisation. Radial artery injury will be quantified pre- and post- angiography using Optical Coherence Tomography. The participants will also have radial endothelial function assessed using flow-mediated dilatation at baseline, 24 hours, one week, one month and three months post- angiography. Blood will be taken pre and 24 hours post angiography for characterisation of endothelial progenitor cell numbers and function. The hypothesis is that trans-radial catheterisation will cause a reduction in flow-mediated dilatation which peaks at 24 hours and recovers at three months. The investigators hope to correlate the rate of this recovery with peri-procedural progenitor cell numbers.

What is being measured

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

  1. Change in Flow-mediated dilatation

    Radial artery flow-mediated dilatation will be assessed at the above stated time points

    Measured: baseline, 24 hours, one week, four weeks and three months post-angiography

Secondary outcomes (2)
  1. Radial artery injury

    Optical coherence tomography examination of the radial artery will be made at baseline and following sheath insertion.

    Measured: Baseline and up to 1 hour Post angiograpy sheath insertion

  2. Endothelial progenitor cell number an function Endothelial progenitor cell number and function

    Measured: Baseline and at 24 hours post-angiogram

Questions about this trial

What is this clinical trial studying?

An observational study of Atherosclerosis, run by University of Edinburgh at 1 site in United Kingdom.

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 4 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 7 Apr 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 United Kingdom. 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?

Change in Flow-mediated dilatation (time frame: baseline, 24 hours, one week, four weeks and three months post-angiography). 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 NCT02147119, which also lists 1 linked publication.

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 7 Apr 2017.
