Figure 2.
Regional EFV subcategorized according to myocardial perfusion status. Myocardial ischemia is associated with significantly elevated EFV in the distribution of the right coronary artery (RCA) and left anterior descending coronary artery (LAD). No significant differences between normal perfusion imaging and ischemia are detectable in the region of the left circumflex artery (LCx). EFV in the territory of the LCx is considerably smaller compared to RCA and LAD territories in the presence of both normal and stenotic coronary arteries (*P < 0.05 vs normal RCA; #P < 0.01 vs normal LAD; †P < 0.05 vs LAD and RCA.
