Fractional flow reserve in unstable angina and non-ST-segment elevation myocardial infarction experience from the FAME (Fractional flow reserve versus Angiography for Multivessel Evaluation) study

, 2011
The use of fractional flow reserve (FFR) to guide percutaneous coronary intervention (PCI) is well established in stable angina (SA) but has not been prospectively researched in unstable angina (UA) or non–ST-segment elevation myocardial infarction ...

Hemodynamic Significance of APEXCT Coronary Angiography Combined With Dynamic CT Myocardial Perfusion Imaging in Assessing Restenosis After Coronary Stenting

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT This study aimed to evaluate the hemodynamic significance of in‐stent restenosis (ISR) by using a combined anatomical‐functional approach with photon‐counting CT coronary angiography (APEX‐CT CTA) and dynamic CT myocardial perfusion imaging (CT‐MPI). We prospectively enrolled 239 symptomatic patients at least 9 months after PCI.

Fractional flow reserve versus angiography for guidance of PCI in patients with multivessel coronary artery disease (FAME): 5-year follow-up of a randomised controlled trial [PDF]

, 2015
In the Fractional Flow Reserve Versus Angiography for Multivessel Evaluation (FAME) study, fractional flow reserve (FFR)-guided percutaneous coronary intervention (PCI) improved outcome compared with angiography-guided PCI for up to 2 years of follow-up.

Numerical and experimental investigations of Fractional Flow Reserve (FFR) in a stenosed coronary artery [PDF]

E3S Web of Conferences, 2019
The coronary artery is numerically investigated based on CFD techniques for measuring the severity of stenosis. In mild cases, medication is often preferred whereas for severe cases surgical intervention is `required but most of the cases fall in between. Thus, it poses a problem for clinicians in choosing an appropriate action.

Hyperdominant Left Circumflex Artery Challenging Conventional Paradigms and Current Guideline Recommendations: A Comprehensive Literature Review and Case Series

Clinical Case Reports, Volume 14, Issue 11, November 2026.
Summary of the patient's presentation, diagnostic evaluation, treatment, and follow‐up. ABSTRACT Despite its rarity in the general population, left dominant coronary circulation with a hyperdominant left circumflex artery (LCx) has been associated with a more severe risk for ischemic and coronary artery disease. The concealment of an isolated posterior

Diffusely impaired myocardial perfusion in patients with suspected coronary artery disease: Clinical utility of relative perfusion

Clinical Physiology and Functional Imaging, Volume 46, Issue 6, November 2026.
Abstract Background In patients with suspected coronary artery disease (CAD), diffusely impaired hyperaemic myocardial blood flow (MBF) may indicate a multivessel epicardial CAD but also impaired coronary microcirculation. We assessed whether relative hyperaemic MBF—that is, the ratio of the lowest to the highest regional hyperaemic MBF—predicts ...
