The predictive value of combined 123iodine-labelled 15-(p-iodophenyl)-3R,S-methyl pentadecanoic acid imaging (123I-BMIPP) and early technetium-99m (99mTc)-tetrofosmin imaging was compared with combined 123I-BMIPP and delayed 99mTc-tetrofosmin or 123I-BMIPP and thallium-201 (201Tl) imaging for functional outcome of stunned myocardium after acute myocardial infarction (AMI) in 37 patients with AMI. All patients underwent successful percutaneous coronary intervention with/without stenting within 24 h of symptoms. Resting 201Tl, 99mTc-tetrofosmin and 123I-BMIPP imaging were performed within 10 days of hospital admission; 99mTctetrofosmin imaging was also performed 6 months later. Segments were mismatched when the 123I-BMIPP score was greater than the 99mTc-tetrofosmin or 201Tl scores, and were matched when all scores were the same. Left ventricular function was estimated using wall motion score. Sensitivity and regional wall motion were significantly better in mismatching 99mTc-tetrofosmin-early/123I-BMIPP segments than mismatching 201Tl/123I-BMIPP or 99mTc-tetrofosmin-delayed/123I-BMIPP segments. It is concluded that mismatching of 123I-BMIPP and early 99mTctetrofosmin uptake can predict improvement in wall motion of stunned myocardium better than the other two imaging combinations.
