Sponsor's own description

Physiology-based decision-making about the need for revascularisation in patients with stable coronary heart disease has consistently proven better clinical outcomes than a merely anatomical approach. However, against the current recommendations, revascularisation in most of patients with chronic coronary syndromes still relies on coronary angiography alone. The increase in costs and in procedural complexity of wire-based physiology may explain the latter. Therefore, a novel non-invasive functional quantitative flow ratio (QFR) index was created in order to solve it. A retrospective and multicentre study is performed to assess the 5-year prognosis of patients undergoing coronary angiography through a centralized QFR analysis. Consecutive participants with confirmed or suspected diagnosis of stable coronary disease who underwent a coronary angiography between 01/01/2015 and 12/31/2015 were included. Aims of the study: * To evaluate the prognosis of stable coronary disease depending on the functional assessment of coronary artery disease. * To determine the % of percutaneous coronary interventions that could be avoided if this study had been carried out through functional assessment of coronary artery disease based on 3-dimensional vessel reconstruction.
