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 …

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

BACKGROUND: Achievement of maximal hyperemia of the coronary microcirculation is a
prerequisite for the measurement of fractional flow reserve (FFR). Intravenous adenosine is …

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 …

Background Various methods are used to induce maximal hyperemia for physiologic
studies, but the feasibility and efficacy of continuous intracoronary (IC) infusion of adenosine …

Intravenous adenosine is considered the drug of choice to obtain maximum hyperemia in
the measurement of the fractional flow reserve (FFR). However, comparative studies …

BACKGROUND: The achievement of maximal vasodilatation of the coronary microvessels is
mandatory for the accurate determination of fractional flow reserve (FFR); the optimal dosing …

BACKGROUND: Inducing stable maximal coronary hyperemia is essential for measurement
of fractional flow reserve (FFR). We evaluated the efficacy of the intracoronary (IC) …

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

Objectives: This study sought to compare increasing doses of intracoronary (IC) adenosine
or IC sodium nitroprusside versus intravenous (IV) adenosine for fractional flow reserve …
