SORT OUT IX STEMI OCT is a randomized 1:1 study comparing the polymer-free Biolimus-eluting BIOFREEDOM stent with a biodegradable-polymer Sirolimus-eluting ORSIRO stent patients with STEMI treated with primary PCI.~Vascular healing index (uncovered stent struts, malapposed stent struts, maximal intima coverage and accumulated extra-stent lumen volume) assessed with optical coherence tomography (OCT) 1 month after primary PCI.~Patients will be enrolled by the investigators and randomly allocated to treatment groups after diagnostic coronary angiography and before primary PCI. A web based Trial Partner randomization system will be used.~OCT will be performed with the frequency-domain OPTIS OCT system and Dragonfly™ Imaging Catheter during the index procedure and after 1 months.
The aim of the Danish Organization for Randomized Trials with Clinical Outcome (SORT OUT) IX STEMI OCT is to compare early vascular healing of the polymer-free Biolimus-eluting BIOFREEDOM stent with a biodegradable-polymer Sirolimus-eluting ORSIRO stent in patients with ST-segment elevation myocardial infarction (STEMI) treated with primary percutaneous coronary intervention (PCI).
