Overview
The present study is a prospective randomized clinical trial aimed to compare the therapeutic strategy of angiography-guided versus concurrent OCT/FFR-guided intervention in patients with coronary artery disease.
Description
Most previous clinical trials have assessed various interventional strategies guided by intravascular imaging (intravascular imaging-guided PCI), fractional flow reserve (FFR-guided PCI), or conventional angiography (angiography-guided PCI) to compare differences in treatment outcomes. Until now, it remains unclear whether optimizing procedures based on both intravascular imaging and fractional flow reserve indices would lead to improved treatment outcomes compared to PCI guided solely by conventional angiography. Moreover, there are no studies comparing a treatment strategy that combines optical coherence tomography (OCT) and FFR to angiography-guided procedures. Hence, this study aims to compare the clinical effectiveness and therapeutic impact of concurrent guidance using FFR and OCT in patients undergoing coronary artery stent implantation, as compared to procedures guided solely by conventional angiography.
