NCT05209503

Brief Summary

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).

Study Arms (2)

AccuFFRangio Group

EXPERIMENTAL

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.

Other: AccuFFRangio-guided strategy

Angiography Group

ACTIVE COMPARATOR

The Angiography Group was defined as PCI treatment for non-IRA when diameter stenosis \> 70% based on angiographic results.

Other: Angiography-guided strategy

Interventions

AccuFFRangio-guided strategyOTHER

In this study, the AccuFFRangio-guided strategy will be applied to in the AccuFFRangio group in which calculation of the AccuFFRangio values of all target coronary arteries with lesions with diameter stenosis of ≥ 50% (visual estimation) and with suitability to PCI revascularization will be carried out. If AccuFFRangio ≤ 0.80, then simultaneous PCI revascularization of target blood vessels will be carried out. If AccuFFRangio \> 0.80, then no PCI revascularization of target blood vessels will be carried out.

AccuFFRangio Group
Angiography-guided strategyOTHER

In this study, CAG-guided strategy will be used for the control group, i.e., in accordance with current guideline recommendations, all target coronary arteries with lesions with diameter stenosis of ≥ 70% (visual estimation) and suited for PCI revascularization will undergo PCI revascularization.

Angiography Group
