Study Overview
Brief Summary
The RIGHT study is a large randomized study dedicated to post-PPCI anticoagulation in STEMI patients. The investigators propose to evaluate the clinical efficacy and safety of anticoagulation prolonged for at least 48 hours after the procedure vs. no prolongation of anticoagulation after procedure in patients with STEMI treated with bivalirudin during PPCI (primary hypothesis). When allocated to anticoagulation prolongation by randomization, the subject will be assigned to UFH, enoxaparin or bivalirudin (same regimen allocated by centre) for at least 48 hours after PPCI. The results from this study are expected to provide guidance on the risk/benefit of post-procedural anticoagulation in patients with STEMI.
Detailed Description
A minor change of time of randomization after prolongation of bivalirudin infusion at PCI dose up to 4 hours on protocol at September 19,2018. Reasons: a minor change concerning the timing of randomization considering the current local practice in some centers that use the 4 hour infusion of bivalirudin just after PCI. It remains in agreement with the current international guidelines and with the drug label in China. There is no change in drugs used and doses of these drugs once the randomization occurs.
