摘要
为评价核素心肌灌注显像对冠心病诊断的价值，并用其判断血运重建术的疗效，对 ７２ 例冠心病或可疑冠心病患者行冠脉造影术与核素心肌灌注显像，并对其中１５ 例患者在血运重建术后复查心肌灌注显像。结果表明核素心肌显像诊断冠心病的灵敏度与特异性分别为９５％ 与 ８６％ ；血运重建术后平均缺血节段数无明显改变，平均缺血分数显著降低。结论：①核素心肌显像对冠心病诊断的灵敏度与特异性均很高；②血运重建术后，原缺血心肌供血明显改善。
The evaluation of m yocardial perfusion im aging in the diagnosis ofcoronary heart disease and the effectof revascularization procedures Cai Siyu1 Yu Feng1, Liu Qichang21 Departm ent of Cardiology, 2 Departm ent of Nuclear M edicine, Second Affiliated Hospital of Zhejiang M edical University, Hangzhou,310009 Abstract The purpose of this study w as to assess the value of m yocardial perfusion im aging inthe diagnosis of coronary artery disease( C A D) and the effect of revascularization procedures. Therefore, 72 patients w ith C A D or suspected C A D underw ent coronary angiography and Technetium 99m M I B Iim aging,and 15 of them received a second m yocardial im aging after thecoronary revascularization. The results show ed that the sensitivity and specificity of m yocardialim aging for detection of C A D w ere 95% and 86% , respectively. There w as no significantdifference in the m ean ischem ic segm ent after revascularization,w hile the m ean ischem ic scoredecreased greatly. The results suggested that m yocardialperfusion im aging w as a highly sensitiveand specific m ethod for detection of C A D and the blood supply im proved significantly aftercoronary revascularization.
