MYOCARDIAL VIABILITY INDEX IN CHRONIC CORONARY-ARTERY DISEASE - TECHNETIUM-99M-METHOXY ISOBUTYL ISONITRILE REDISTRIBUTION
The purpose of this study was to evaluate whether an additional redistribution image after a rest (TC)-T-99m-MIBI injection enhances detection of viable myocardium and predicts functional recovery after coronary revascularization in patients with chronic coronary artery disease (CAD). Methods: Thirty-one patients (29 men, mean age 55 +/- 10 yr) with proven CAD and left ventricular (LV) dysfunction (ejection fraction 39% +/- 9%) underwent resting Tc-99m-MIBI tomography with initial (1 hr) and delayed (5 hr) images. Within 1 wk of MIBI imaging, all patients underwent rest-redistribution (TI)-T-201 imaging. Eight patients also underwent two-dimensional echocardiography before and 5 +/- 3 mo after coronary revascularization. Results: On the initial Tc-99m-MIBI images, 302 myocardial segments were normal, 183 showed moderate and 197 severe reduction of tracer uptake. Of these 197 segments, 47 (24%) demonstrated increased tracer uptake (greater than or equal to 10% versus initial) on delayed images (from 43% +/- 8% to 60% +/- 8%, p
