目的定量评价核素心肌断层显像（ＳＰＥＣＴ）与冠状动脉造影血管病变的相关性方法对５０例冠心病（ＣＡＤ）病变血管狭窄程度、狭窄面积与ＳＰＥＣＴ心肌缺血程度、缺血面积进行双定量分析比较．结果病变血管直径、血管面积和血管狭窄程度、血管狭窄面积相关性很高， ｒ＝０．９８、０．９３；血管狭窄程度、血管狭窄面积与ＳＰＥＣＴ心肌缺血程度、心肌缺血面积相关性较低（ｒ＝－０．２６、０．３３）；病变血管直径与 ＳＰＥＣＴ心肌缺血面积不相关（ｒ＝０．０４）；病变血管狭窄面积与ＳＰＥＣＴ心肌缺血程度负相关（ｒ＝０．１２）结论冠脉造影病变血管缺血程度、病变血管面积与ＳＰＥＣＴ心肌缺血程度、心肌缺血面积两种检查的相关性较低，但其间有内在联系，供临床参考．
Objective To quantitatively evaluate the correlation between SPECT and coronary artery angiography in 50 patients with coronary artery disease (CAD), and to determine the extent of stenosis, the area of stenosis and the degree of myocardial ischemia, the area of ischemia analyse and compare. Results The diameter of vascular lesion, the area of blood vessel, the degree of stenosis and the area of vascular stenosis were highly correlated (r = 0.98,0.93). The degree of vascular stenosis, the area of stenosis and the extent of myocardial ischemia and the area of myocardial ischemia (R = -0.26,0.33). The diameter of lesion vessels was not correlated with SPECT myocardial ischemia area (r = 0.04). The area of vascular stenosis was negatively correlated with SPECT myocardial ischemia (r = 0 .12) CONCLUSIONS: The degree of ischemia of coronary angiography, the area of vascular lesion and the extent of myocardial ischemia and SPECT myocardial ischemia two tests of low correlation, but there is an inter-relationship between for clinical reference.
