Each patient had FFR measured using adenosine 140 mcg\/kg\/min IV, and following return to baseline, FFR was measured using regadenoson 400 mcg IV, which then was reversed with aminophylline 150\u2009mg IV. Time to baseline hemodynamics was measured. Agreement between the two assessments was compared using linear regression.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>FFR results were similar with both agents (<jats:italic>R<\/jats:italic><jats:sup>2<\/jats:sup> = 0.935, <jats:italic>P<\/jats:italic> &lt; 0.0001). Also, using the 0.80 cutoff for significantly depressed FFR, there was no divergence regarding studies' significance.
