目的 观察冠状动脉造影 (CAG)与核素心肌组织血流灌注显像 (SPECT)的相关性及用 SPECT对冠状动脉内支架植入术后的疗效评价。方法 于冠心病 (CAD)患者 CAG之后 ,放支架之前利用血管造影机自配电脑分析软件 ,对病变血管直径狭窄和面积狭窄百分比进行自动分析 ;对冠状动脉内支架植入术前、术后 1周、术后半年 ,分别做静息、潘生丁负荷 SPECT检查。结果 5 1例 CAG血管直径狭窄 (76 .16 % )、面积狭窄 (90 .37% )与术前静息 SPECT血流灌注损害程度 (6 3.5 0 % )的相关系数分别为 r=0 .2 5 4、r=0 .176 ,存在一定的相关性 ;血管狭窄程度、血管狭窄面积与术前静息SPECT血流灌注损害面积 (71.17% )的相关系数分别为 r=0 .2 91、r=0 .32 7,存在一定的相关性。 5 0例术后 1周静息血流灌注损害程度 (4 5 .46 % )明显低于术前静息血流灌注损害程度 (6 3.5 0 % ) ,P<0 .0 0 1;2 1例术后半年血流灌注损害程度 (4 3.73% )明显低于术前静息血流灌注损害程度 (6 0 .87% ) ,P<0 .0 0 1。 5 0例术后 1周静息血流灌注损害面积 (5 7.2 2 % )明显低于术前静息血流灌注损害面积 (71.17% ) ,P<0 .0 0 1;2 1例术后半年血流灌注损害面积 (5 4.6 7% )明显低于术前静息血流灌注损害面积 (70 .2 1% ) ,P<0 .0 5。冠状动脉内支架植?
Objective To observe the correlation between coronary angiography (CAG) and radionuclide perfusion imaging of radionuclide myocardial tissue (SPECT) and to evaluate the effect of SPECT on intracoronary stent implantation. Methods After coronary artery disease (CAD) patients with CAG, the angiography machine was used with computer software to analyze the percentage of stenosis and stenosis area before stent placement. Before coronary stent implantation, Week, six months after surgery, respectively, resting, dipyridamole SPECT load examination. Results The correlation coefficients of 51 cases of narrowing of CAG (76.16%), stenosis (90.37%) and preoperative resting SPECT perfusion (6 3.5%) were r = 0.2 5 4, r = 0.176, there is a certain correlation between the degree of vascular stenosis, area of stenosis and preoperative resting SPECT perfusion damage area (71.17%) were r = 0.221, r = 0 .32 7, there is a certain correlation. The degree of resting blood perfusion damage in 50 patients 1 week after operation was significantly lower than that of preoperative rest blood perfusion (45.5%, P <0.01 01) For example, the degree of perfusion damage in the first 6 months after surgery was significantly lower than that of preoperative perfusion (4.87%, 4.73%, P <0.01). The area of resting blood perfusion injury (5 7.22%) in 50 cases 1 week after operation was significantly lower than that of preoperative resting perfusion (71.17%), P <0.01; 21 The blood perfusion damage area (5 4.6 7%) in six months was significantly lower than that of preoperative resting perfusion (70.21%), P <0.05.
