This study included 201 patients suffering ST-segment elevation acute coronary syndrome and randomized to the use of optical coherence tomography (OCT) versus conventional angiography for the procedure. OCT-guided group used more stents per patient (1.4 versus 1.2, p = 0.03) and greater release pressure. During control OCT suboptimal results were found in a third of patients (29/105) requiring optimization. Binary restenosis was low and similar for both groups (2% versus 3%, p=ns) as major cardiac events.
Conclusion
Conducting OCT is safe in the context of ST-segment elevation myocardial infarction, observed a low rate of MACE, binary restenosis, stent thrombosis, late lumen loss and a high percentage of struts covered in 2nd generation drug stents.
