Non-invasive fractional flow reserve derived from coronary computed tomography angiography in patients with acute chest pain: Subgroup analysis of the ROMICAT II trial

摘要

Background: Non-invasive fractional flow reserve (FFRCT) derived from coronary computed tomography angiography (CTA) permits hemodynamic evaluation of coronary stenosis and may improve efficiency of assessment in stable chest pain patients. We determined feasibility of FFRCT in the population of acute chest pain patients and assessed the relationship of FFRCT with outcomes of acute coronary syndrome (ACS) and revascularization and with plaque characteristics.
