Transradial Evaluation Study of Diameter Increase After Vasodilatory Drugs Administration. — TRIESTE  

Coronary Artery Disease Clinical Trial

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

Status Active, not recruiting

Clinical Trial Summary

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.

Clinical Trial 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) ;
