| Abstract | [Summary]For prediction of recovery of LV contractility, 99mTc-MIBI gated SPECT at rest and that with dobutamine(DOB)loading were performed in 15 patients with myocardial infarction(MI). Regional % uptake(regional×100/maximal count), % wall thickening[%WT;(ES-ED)×100/ED maximal count), and Δ%WT(%WT at DOB stress-%WT at rest)were calculated for each of 8 segments(seg. ), including 34 MI out of total 120 seg. , which derived from short axis LV count profile. These 34 seg. were divided into two groups, recontractile(18seg. )and nonrecontractile(16seg. ), whether improvement of the wall motion following the intervention(3-5 months)was observed by echocardiography. In the result, there were 7 recontractile seg. in 8 seg. with mildly reduced perfusion(>=normal mean%uptake-2S. D. ), and there were 11 recontractile seg. in 26 seg. with severe reduced perfusion( |
