WebThe mean percent stenosis was 63.91 ± 13.13 SD and, the mean FFR was 0.831 ± 0.0738 SD for IV and 0.832 ± 0.0707 SD for IC adenosine. There was a strong and linear correlation between 2 sets of observations with IV dose and IC adenosine dose (R = 0.964, y = 0.065 + 0.923x; p < 0.001) (y = IV dose, x = IC dose).

Li S, Zhao X, Deng J, Han Y. Effects of intracoronary sodium nitroprusside compared with adenosine on fractional flow reserve measurement. J … WebApr 1, 2012 · High doses of IC adenosine can be relatively safely administered to most patients and a strategy of increasing dose until 600 μg allows obtaining the minimum FFR value in a similar proportion of patients compared with the gold standard IV route that thus still might be reserved to those cases of equivocal FFR after IC adenosine.
WebApr 23, 2015 · Two FFR measurements were performed during intracoronary bolus injection (40 μg for the right and 80 μg for the left … WebHowever, it is surprisingly unclear which IC strategy allows the achievement of FFR values that are comparable to IV adenosine. Objectives This study sought to compare increasing doses of IC adenosine versus IV adenosine for FFR. Methods 30 intermediate coronary stenoses undergoing FFR measurement were prospectively and consecutively enrolled.
