Figure 1 Predictive Value of Stress-Induced Change in WMSI for Hard and Any Events

Panel A demonstrates the wall motion score index (WMSI) (y-axis) during the 3 phases of dobutamine infusion (rest, low-dose infusion, and after peak stress). Within each stage, the mean ± SE of the estimate is shown. As noted, for any events, the difference in WMSI from low dose to peak stress was higher in those experiencing any events (A). As shown in panel B, the resting and peak WMSI was higher in patients experiencing myocardial infarction and cardiac death. CMR = cardiovascular magnetic resonance; DBT = dobutamine.
