About this study

Official title: TransRadIal Evaluation STudy of diamEter Increase After Vasodilatory Drugs Administration: The TRIESTE Randomized Study

Radial artery access use in percutaneous cardiac interventions (PCI) is associated with a lower risk of vascular complications, bleeding and major adverse cardiac events including cardiac death in the long-term follow-up. Intra-radial administration of vasodilatory drugs, transiently painful for the patient, reduces the risk of spasm and is currently the standard technique performed worldwide. However, the efficacy of intravenous administration of vasodilatory drugs has never been evaluated.

Read the detailed description

Multicenter, randomised controlled trial, designed to evaluate the noninferiority of the intravenous administration of vasodilatory drugs in comparison with the actual gold standard intra-arterial radial route, in terms of radial artery diameter increase.

All consecutive patients with stable ischemic disease or stable acute coronary syndrome (NSTEMI - Non-ST elevation myocardial infarction) for whom a coronary procedure is planned will be included in the study. Three groups will be constituted. For all groups, the diameters of both radial arteries will be measured thrice by echo-Doppler: 5 minutes before sheath insertion, immediately before sheath insertion and 5 minutes after sheath insertion. Pain evaluation will be performed after injection of the vasodilatory drugs/placebo in the radial artery:

  • Group 1 (control group): intra-radial administration of the vasodilatory drugs after sheath insertion (verapamil 2.5 mg + isosorbide dinitrate 0.5 mg)
  • Group 2 (intravenous-post): intra-venous administration of the vasodilatory drugs after sheath insertion (verapamil 2.5 mg + isosorbide dinitrate 0.5 mg)
  • Group 3 (intravenous-pre): intra-venous administration of the vasodilatory drugs 5 minutes before sheath insertion (verapamil 2.5 mg + isosorbide dinitrate 0.5 mg)

What is being measured

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

  1. Maximal radial artery diameter dilation, measured by echo-doppler, after administration of vasodilatory drugs by intravenous or intra-radial route.

    Radial artery diameter

    Measured: 5 minutes after vasodilatory drugs administration

Secondary outcomes (3)
  1. Pain evaluation after vasodilatory drugs administration using the intravenous versus intra-radial route

    Scale from 0 to 10, lower values corresponding to lower pain and higher values to intense pain.

    Measured: Procedure (During vasodilatory drugs administration)

  2. Hemodynamic changes after vasodilatory drugs administration using the intravenous versus intra-radial route

    Measure of arterial pressure

    Measured: 5 minutes after vasodilatory drugs administration

  3. Heart rate change after vasodilatory drugs administration using the intravenous versus intra-radial route

    Measure of heart rate.

    Measured: 5 minutes after vasodilatory drugs administration

Questions about this trial

What is this clinical trial studying?

A study testing Intravenous administration of vasodilatory drugs in people with Arterial Spasm and Coronary Artery Disease, run by University of Lausanne Hospitals at 2 sites in Switzerland.

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 9 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 6 Aug 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Switzerland. 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?

Maximal radial artery diameter dilation, measured by echo-doppler, after administration of vasodilatory drugs by intravenous or intra-radial route. (time frame: 5 minutes after vasodilatory drugs administration). 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 6 Aug 2024.
