简要总结
This is a prospective, single-center clinical trial. AccuFFRangio (ArteryFlow Technology Co., Ltd., Hangzhou, China) is a novel method for evaluating the functional significance of coronary stenosis by computing the pressure in the vessel based on angiographic images. The aim of this study was to evaluate the diagnostic accuracy and prognostic implications of AccuFFRangio in patients with ST-segment elevation myocardial infarction (STEMI).

研究组 & 干预措施
AccuFFRangio Group
STEMI patients with multiple lesions who met the requirements of the study were enrolled and received coronary angiography. First, the revascularization of the criminal vessel (PCI) was completed. The patients were randomly grouped and divided into AccuFFRangio Group and Angiography Group if the treatment results were good. The AccuFFRangio Group was defined as non-IRA of these patients who were treated with PCI after angio-FFR measurement with FFR≤0.8.
干预措施: AccuFFRangio-guided strategy (Other)
Angiography Group
The Angiography Group was defined as PCI treatment for non-IRA when diameter stenosis > 70% based on angiographic results.
干预措施: Angiography-guided strategy (Other)
