This study evaluated semiquantitative measures of ischemia
using noninvasive stress perfusion CMR for the detection and quantification of
CAV using invasive coronary angiography as the standard reference on a cohort
of chronic heart transplant patients. Based on angiogram results, patients were
divided into groups by disease severity. The upslope and myocardial perfusion
reserve was measured per segment for each patient based on the AHA 16 segment
model. These values were then correlated to the angiogram results and averaged
by segment to create bullseye plots for each group. As disease severity
increases, both myocardial perfusion reserve and stress upslope decrease.
