Abstract:
Objective To compare and evaluate fractional flow reserve (FFR) by intravenous infusion of adenosine 5’-triphosphate (ATP) through femoral veins and hand dosal veins. To find the feasibility of measuring FFR through ATP infusion at hand dosal veins. Methods A total of 27 patients receiving coronary angiography (CAG) were enrolled. FFR was measured by intravenous injection of ATP through femoral veins and hand dosal veins separately in 31 stenosed coronary arteries. Results A linear correlation between ATP infusion measuring FFR through femoral and hand dosal veins was observed. Heart rates, PR intervals and side effects were of no difference between the 2 routes of ATP infusion (P=0.79, P=0.56, P=0.85). It indicated that ATP infusion[160μg/(kg·min)]measuring FFR through hand dosal veins was compatable to which measuring FFR though femoral veins (y=0.945x+0.0043, R2=0.904, P=0.001). Compared with ATP infusion by femoral vein[from (53.7±15.8) s to (58.2±11.6) s], the time to FFR by infusion ATP measurement by hand dosal veins was longer[(48.7±17.9) s, P=0.015]. Conclusions The FFR measurement through ATP infusion at hand dosal veins has similar results with the FFR measured by femoral veins ATP infusion.
