Figure 4
TAFE-derived coronary blood flow, flow velocity, and microvascular resistance according to diameter stenosis. CBF per myocardium (g) decreased according to the severity of stenosis (A–C). However, flow velocity did not decrease (D), and was accompanied by concomitant reduction of mean luminal area, volume, and microvascular resistance (B,C,E). Boxplots show median and 1st–3rd quartile as box, and 1.5-fold of the interquartile range as whisker. Panel F integrates panels A–E with data as mean ± SE. Curves were fitted by polynomial quadratic models.
