Figure 3. Conventional‐FFR and diastolic‐FFR changes during both adenosine and dobutamine provocation in relations to stress‐echocardiography (SE) results.

Figure 3

A, Conventional‐FFR, and (B) diastolic‐FFR during both adenosine (ADO) and peak dobutamine infusion (DOBmax) in relation to SE results. C, Conventional‐FFR and (D) diastolic‐FFR during dobutamine infusion (10–50 µg/kg/min) in relation to SE results. Dotted lines in all figures represent the ischemic tresholds for conventional‐FFR (0.80) and diastolic‐FFR (0.76). BL indicates basal conditions, before dobutamine infusion; DOB, dobutamine; DOB 10, 10 µg/kg/min of DOB; DOB 20, 20 µg/kg/min of DOB; DOB 30, 30 µg/kg/min of DOB; DOB 40/50/ATR, 40 or 50 µg/kg/min of DOB, or atropine; FFR, fractional flow reserve; SE−, group of patients without stress‐induced ischemia; and SE+, group of patients with stress‐induced ischemia. *P<0.05 vs BL; P<0.05 vs preceding value; P<0.05 vs SE− group.
