目的判断急性心肌梗塞溶栓治疗效果。方法对２１例急性心肌梗塞（ＡＭＩ）患者行溶栓治疗前及治疗后心肌ＳＰＥＣＴ显像并进行定量分析。将每例患者的左室心肌分为２１个节段，在每一节段画一６×６Ｐｉｘｅｌ的ＲＯＩ，计算每一ＲＯＩ的放射性计数，以计数最高节段作为１００％，其余节段的放射性摄取以最高计数节段的百分值表示。结果患者分为３组，组１为溶栓成功者，共１３例，左室心肌共分为２７３个节段，其中１２６个节段不正常，按各节段得分总和计算，得分为１６４±８４，溶栓治疗后有４５个节段恢复正常（３５７％），平均得分８９±７１，较治疗前明显改善（ｔ＝２５２，Ｐ＜００１）；组２为溶栓未成功者，共３例，６３个节段，其中３９个节段不正常，平均得分２５７±６３，与组１间有明显差别（ｔ＝１７７，Ｐ＜００５），经治疗后有２个节段恢复正常（５１％），平均得分２３３±７３，与治疗前比较无明显差别（ｔ＝０４３，Ｐ＞００５）；组３为未溶栓组，共５例，１０５个节段，其中５２个节段不正常，平均得分１７６±６９，与组１、２间无明显差别（ｔ３、１＝０３８，ｔ３、２＝１１４，Ｐ＞００５），经治疗后有６个节段恢复正常，（?
Objective To determine the effect of thrombolysis in acute myocardial infarction. Methods Twenty-one patients with acute myocardial infarction (AMI) underwent myocardial SPECT before and after thrombolytic therapy and analyzed quantitatively. The left ventricular myocardium of each patient was divided into 21 segments, a 6 × 6 pixel ROI was plotted for each segment, and the radiological counts for each ROI were calculated to count the highest segment as 100% and the remaining segments for radioactivity Ingestion is expressed as a percentage of the highest count segment. Results The patients were divided into 3 groups. Group 1 was successful in thrombolysis, with a total of 13 cases. The left ventricle myocardium was divided into 273 segments, of which 126 segments were abnormal. The score was 16 for each segment. 4 ± 84, 45 segments recovered to normal after thrombolytic therapy (357%), the average score was 89 ± 71, which was significantly improved compared with that before treatment (t = 252, P <0 01). Group 2 was unsuccessful in thrombolysis. There were 3 cases and 63 segments in total, of which 39 segments were abnormal. The average score was 25.7 ± 6.3, which was significantly different from that of group 1 (t = 1 77, P <005). After treatment, 2 segments returned to normal (51%) with an average score of 233 ± 73, no significant difference compared with that before treatment (t = 043 , P> 005); group 3 was not thrombolysis group, a total of 5 cases, 105 segments, of which 52 segments were abnormal, with an average score of 176 ± 69, Obvious difference (t3,1 = 038, t3,2 = 114, P> 0 05), after treatment, six segments returned to normal, (?
