Distal versus conventional transradial artery access for coronary catheterization in patients with ST- elevation myocardial infraction (STEMI) (DR-STEMI): Rationale and design of an international, multicenter, randomized trial
Study context
- Population
- Patients with STEMI undergoing coronary angiography and interventionsplanned enrollment (277 patients in each treatment arm)
- Participants
- 554 patients
- Planned comparison
- Distal transradial access (dTRA) versus conventional transradial access (TRA) access in patients with STEMI undergoing coronary angiography and interventions
- dTRAn = 277
- TRAn = 277
- Primary endpoint
- Needle-to-wire time (time between the puncture of the radial artery and wire crossing of the infarct-related artery); noninferiority of dTRA to conventional TRA
Methodological details1:1 randomization, all-comers screening
