缺血性心肌病和非缺血性心肌病核素心肌断层显像的定量分析

The Quantitation Analysis of Radionuclide Myocardial Perfusion ImagingWith Ischemic and Nonischemic Cardialmyopathy

本文观察了１９例缺血性心肌病（ＩＳＣＭ）和１９例非缺血性心肌病（ＮＩＳＣＭ）患者的核 心肌断层显像与超声心动图，并且结合例正常对照组心肌定量结果进行定量分析，结果证实ＩＳＣＭ组与ＮＩＳＣＭ组均伴不同程度的左室心腔扩大，并与ＵＣＧ结果一致，ＩＳＣＭ且心肌显像目 有４８个减低及缺损节段；定量分析见１４３个减低及缺损节段。两个患者病变节段数点总节段的１１．６０－６１．１０％，平均２７．１６％。

To determine if 99mTc-MIBI myocardial perfusion imaging can distinguish ischemiccardialmyopathy (ISCM) from ischemic cardialmyopathy (NISCM). Nineteen cases with ISCMand nineteen cases with NISCM were evaluation by the rest myocardial perfusion imaging quantita-tive analysis. All patients had a left ventricular ejection fraction <50%. We compared the quanti-tative parameters among ISCM, dilate cardialmyopathy (DCM) and essetial hypertension heartdisease (EH). The results showed that there were uptake decrease and defect segments 143 in IS-CM and 21 segments in DCM (P<0. 01). Patients with ISCM had more decrease and defect seg-ments (11. 60~61. 10% per patients, average 27. 16% ) than did patients with DCM group (3. 50~11. 52% per patient, average 6. 39% ). There were 50 increase segments with EH and 19 seg-ments with DCM (P<0.01). Patients with EH had more increased takeup segments (17. 20~50% per patient, average 1. 23% ) than did patients with DCM (0~10. 72% per patient, average7. 84%).
