Objectives: This study classified and quantified the variation in fractional flow reserve (FFR)
due to fluctuations in systemic and coronary hemodynamics during intravenous adenosine …

Background—We studied the hemodynamic response to intravenous adenosine on
calculation of fractional flow reserve (FFR). Intravenous adenosine is widely used to achieve …

Background—Measurement of fractional flow reserve (FFR) constitutes the current gold
standard to evaluate the hemodynamic significance of coronary stenoses. Limited data …

Objectives: This study sought to compare fractional flow reserve (FFR) with the
instantaneous wave-free ratio (iFR) in patients with coronary artery disease and also to …

Background Continuous intravenous adenosine infusion reportedly produces stable and
maximal hyperemia to allow for fractional flow reserve (FFR) measurement; however …

Objectives: The purpose of this study was to investigate the effects of increasing dose of
intracoronary adenosine on fractional flow reserve (FFR) measurement. Backgrounds: FFR …

Objectives: This study compared the diagnostic performance with adenosine-derived
fractional flow reserve (FFR)≤ 0.8 of contrast-based FFR (cFFR), resting distal pressure …

Background Fractional flow reserve (FFR) is a measure of coronary stenosis severity that is
based on pressure measurements obtained at maximal hyperemia. The most widely used …

Objectives: The aim of this study was to compare site-reported measurements of fractional
flow reserve (FFR) with FFR analysis by an independent core laboratory (CL). Background …

Importance Whether the improvement in myocardial perfusion provided by percutaneous
coronary intervention (PCI) is associated with symptomatic relief or improved outcomes has …
