About this study

The radial approach for a coronary angiography is currently adopted by several centers because of its simplicity. The radial artery spasm is the main inconvenient. Nitrates in intra-arterial have been widely studied in prevention of this spasm. No studies have compared the different routes of administration of nitrates as a patch and a continuous intravenous injection.

Read the detailed description

The radial approach is favored for coronary angiography due of several advantages: reduction of local bleeding risk, even in the most hemorragiparic situations, decreased downtime and time reduction of hospitalization, improved patient ulterior comfort. However, this approach is subject to an immediate major complication that is the radial artery spasm (RAS) which, according to the criteria used, has an average incidence of 30%. The administration of a vasodilator just before coronary angiography procedure enables an increase of the radial artery diameter and thus a decrease of friction probes. Theoretically this prevents the occurrence of the RAS.

The literature re-counts several vasodilator product tests (DN calcic blocker, magnesium sulfate, alpha-adrenergic antagonist ...) and various routes of administration (direct intravenous route (IV), subcutaneous injected route, direct intra-arterial route (IA)). Overall intra-arterial DN appears to be more efficient. The downside is a brief, painful thermal sensation but intense and notably unpleasant. IV injection is better tolerated but it was a direct injection and without proof of its superiority over IA. The para-radial subcutaneous injection has only been studied to facilitate access to the radial artery. The investigators randomized study compares, for the first time, the effectiveness of the transdermal administration of trinitrine (D) and continuous intravenous of dinitrate isosorbide (V) to dinitrate isosorbide intraarterial (A) standard.

What is being measured

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

  1. Radial artery diameter

    With the help of an arterial doppler, measure of the radial artery diameter after injection of dinitrate isosorbide at the beginning and at the end of the procedure (objective measure)

    Measured: Day of administration

  2. Probe friction

    Probe friction, as experienced by the operator (subjective measure)

    Measured: Day of administration

  3. Pain

    Pain felt by the patient in the forearm (subjective measure)

    Measured: Day of administration

  4. Radial artery occlusion

    Evaluation of the radial artery occlusion 3 months post procedure

    Measured: 3 months post procedure

Questions about this trial

What is this clinical trial studying?

A study testing dinitrate isosorbide and nitroglycerine in people with Coronaropathy, run by Brugmann University Hospital at 1 site in Belgium.

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 3 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 7 Oct 2014. 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 Belgium. 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?

Radial artery diameter (time frame: Day of administration). The study lists 4 primary outcomes in all. 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 7 Oct 2014.
