WebMay 1, 2024 · Results Patients with CT-FFR > 0.8 were significantly less likely to require further investigation with coronary angiography (p: < 0.00001) than those with CT-FFR < 0.8. The use of CT-FFR significantly reduced need for further functional imaging (6% vs 26%) (p: 0.00012).

WebFractional Flow Reserve – Computed Tomography (FFR-CT) is a type of non-invasive procedure (no incisions required/small puncture/low to moderate sedation) which uses HeartFlow Analysis, to provide your doctor with a 3D model of your coronary arteries (arteries that supply blood to your heart) as a way to identify any potential blockages ... WebMay 16, 2024 · For patients with ST-elevated myocardial infarction (STEMI) undergoing complete revascularization, percutaneous coronary interventions (PCI) guided by fractional flow reserve (FFR) relative to angiography-guided PCI do not result in significantly lower risk of death or events, according to data from the randomized FLOWER-MI trial.
