Objectives
Narrative objectives1
The aim of this study is to assess the comprehensive significance of functional ischemia assessment and its usefulness in determining the optimal treatment approach, by performing three-dimensional quantitative analysis of preoperative coronary angiography images and non-invasively calculating the Quantitative Flow Ratio (QFR) for patients with three-vessel coronary artery disease who have undergone initial coronary revascularization.
