Monocyte CD11b results. (A) Comparison between levels in the coronary artery proximal and distal to the lesion. (B) Correlation between %DS and absolute increase in mean fluorescence intensity (MFI) from the proximal artery (PA) to the distal artery (DA). (C) Comparison between lesions with ≤ 50% stenosis and > 50% stenosis for absolute increase from PA to DA. (D) Correlation between log peak shear stress and absolute MFI increase from PA to DA. DS indicates diameter stenosis. Solid bars or boxes with error bars represent mean ±SD. r and P values were obtained from correlation analysis; solid lines were derived from linear regression analysis; dotted lines intersect y-axis = 0. *P < .05.
