What this trial studies

This clinical trial evaluates the effectiveness of rivaroxaban, a direct oral anticoagulant, in preventing radial artery occlusion (RAO) following transradial access during coronary angiography or percutaneous coronary intervention. Participants will receive a daily dose of 15mg of rivaroxaban for seven days post-procedure. The study aims to determine if this post-procedural anticoagulation can reduce the incidence of RAO, which is a common complication that limits future access to the radial artery. The trial is designed to provide insights into the safety and efficacy of this approach compared to traditional methods.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older undergoing diagnostic coronary angiography or percutaneous coronary intervention via the transradial approach.

Not a fit: Patients with a high risk of bleeding or those who have had recent complications at the access site may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could significantly reduce the risk of radial artery occlusion, improving future treatment options for patients requiring cardiac procedures.

How similar studies have performed: While the use of intraprocedural anticoagulation has shown promise, the specific approach of post-procedural anticoagulation with rivaroxaban is novel and has not been extensively tested in prior studies.
