This trial is registered with, NCT01014273.īetween June 6, 2006, and Nov 3, 2010, 7021 patients were enrolled from 158 hospitals in 32 countries. Patients and investigators were not masked to treatment allocation. All other outcomes were as reported by the investigators. A masked central committee adjudicated the primary outcome, components of the primary outcome, and stent thrombosis. Key secondary outcomes were death, myocardial infarction, or stroke and non-CABG-related major bleeding at 30 days. The primary outcome was a composite of death, myocardial infarction, stroke, or non-coronary artery bypass graft (non-CABG)-related major bleeding at 30 days. Patients with ACS were randomly assigned (1:1) by a 24 h computerised central automated voice response system to radial or femoral artery access.

The RadIal Vs femorAL access for coronary intervention (RIVAL) trial was a randomised, parallel group, multicentre trial. We aimed to assess whether radial access was superior to femoral access in patients with acute coronary syndromes (ACS) who were undergoing coronary angiography with possible intervention. Small trials have suggested that radial access for percutaneous coronary intervention (PCI) reduces vascular complications and bleeding compared with femoral access.
