Figure 4.

Comparisons of coronary flow reserve size-severity cumulative histograms of PET before and after revascularization by the Kolmogorov–Smirnov test for the 283 pre-post-revascularization paired PET’s, and pre-revascularization PET 1 having (A) severely reduced coronary flow reserve; (B) no severely reduced coronary flow reserve in the pre-revascularization PET 1; and normal CFC for ≥90% of left ventricle in the pre-revascularization PET 1 (C), showing improved (D) or worsened survival probability for baseline severely reduced coronary flow reserve (E), and markedly worse survival probability after revascularization of no severely reduced coronary flow reserve (F)
