Data are presented as mean SD or number (%) as appropriate; statistically significant 99mTc-MIBI versus 99mTc-N-DBODC5 ( < 0.05); paired Student’s -test was used; LVEF: left ventricular ejection fraction; EDV: end-diastolic volume; ESV: end-systolic volume; SSS: summed stress scores; SRS: summed rest scores; SDS: summed difference scores; TID: transient ventricular dysfunction.
