Physiology & Optical Coherence in STEMI

June 19, 2019 updated by: Han Yaling, Shenyang Northern Hospital

A Prospective Evaluation of Clinical Impact of Physiology & Optical Coherence Tomography Guided PCI in STEMI Patients Without Undergoing Primary PCI

The objective of this study is to prospectively evaluate the outcomes of different treatment pathways using a Physiology & Imaging guided PCI in patients with STMEI.

A multi-centre study that will prospectively enrol consecutive STEMI patients who don't receive primary PCI within 48 hours after symptom onset because of different reasons.

STEMI patients with culprit lesion stenosis between 0%-90% will be included in this study and randomized to angiography-guided, FFR-guided or OCT guided PCI groups.

Participant Group / Arm
Intervention / Treatment
Active Comparator: angiography-guided PCI
Procedure: function or imaging guided PCI
FFR may be good tools to differentiate patients with STEMI who may not need stent implantation from those who need Optical coherence tomography (OCT) can visualize the microstructure of culprit and the OCT characteristics were validated by histology
