↵a Forty-eight regions with reduced wall motion (less than or equal to −1 SD) at baseline, reduced sestamibi uptake (≤70%) and successful revascularization are analyzed. Numbers in parentheses are number of regions with a change in regional wall motion (Δ RWM) greater than or equal to the threshold. DA = diagnostic accuracy; NPV = negative predictive value (lack of improvement in regions with reduced perfusion but no mismatch); PPV = positive predictive value (improvement of function above threshold in regions with perfusion/metabolism mismatch); Sens = sensitivity; Spec = specificity.
