Early relationship (ie, day 5) between shear stress (dynes/cm2) and positive remodeling of saphenous vein conduits stratified according to the number of injuries found on intraoperative optical coherence tomography. The plots illustrate that luminal shear stress showed a significant relationship to the degree of diameter change noted in conduits with <4 injuries (R2 = , p < ; blue line and squares). In comparison, conduits with ≥ 4 injuries (R2 = , p = 0.396; red line and diamonds) had a blunted dilation response to shear stress.

4. Fig 3
Relationship between change in graft diameter early (day 5) and late (6 months post) as compared to the diameter of the conduit measured intraoperatively (day 0). (post operative day 5) Plot demonstrates a significant relationship (R2 = 0.792, p = 0.005) of the ability of the conduit to undergo positive remodeling at day 5 and maintain luminal diameter at 6 months.
