Figure 3 Flow diagram detailing the 94 subjects undergoing exercise myocardial perfusion imaging. Subjects were divided based on a flow-mediated dilation (FMD) cut-point of 10%. Of the 54 subjects with an FMD <10%, 21 had positive exercise myocardial perfusion imaging (ExMPI), while 33 had no evidence of coronary artery disease (CAD). The sensitivity of an FMD <10% for CAD was 91%. Two of the 40 subjects with an FMD  10% had CAD by ExMPI resulting in a negative predictive value of 95%.
