摘　　要：目的探讨核素心肌灌注显像正常而冠状动脉造影有病变患者的影响因素。方法我们对267例临床进行冠状动脉造影证实冠脉有病变的患者而核素心肌运动负荷灌注显像正常患者的临床检查资料进行回顾性分析,并比较两者的差异。结果所有患者均按要求完成运动负荷心肌灌注显像,其中97例(34.8%)运动负荷试验达到了满意的次极量运动心率。267例冠脉造影显示单支病变168例(62.9%),双支血管病变61例(22.8%),三支血管病变35例(13%),单支左主干血管病变3例(1.12%);35例三支病变中有27例(77%)各支血管之间的狭窄程度相差≤20%,显示狭窄病变较均衡。267例患者狭窄冠状动脉共410支,其中左前降支188支(45.9%)、左回旋支106支(25.9%)、右冠状动脉104支(25.4%)、左冠状动脉主干12支(2.9%);狭窄程度为50%～70%的有175支(42.7%)、70%～90%的有203支(49.5%)、90%～100%的有32支(7.8%)。结论核素心肌灌注显像阴性而冠状动脉造影狭窄多出现在运动量不足、轻中度狭窄患者、单支病变及均衡性三支病变患者。Objective To study of myocardial perfusion imaging normal and disease patients with coronary angiography the impact of factors. Methods We conducted 267 cases of coronary angiography confirmed coronary artery disease patients and a radionuclide myocardial perfusion imaging exercise load normal patient＇s clinical examination retrospective analysis of data and compare the difference. Results All patients completed according to requirements of campaign stress myocardial perfusion imaging, of which 97 cases（34.8%）movement to achieve a satisfactory stress test, the maximal exercise, heart rate. 267 cases of coronary angiography showed that single-vessel 168 cases（62.9%）, double-vascular lesions in 61 cases（22.8%）, three vascular lesions 35 cases（ 13% ）,single Zhizuo tnmk vascular lesions three cases（ 1.12%）; 35 cases of three lesions in 27 patients（77% ） of the vessels extent of the difference between the narrow≤ 20%, shows a narrow lesions more balanced. 267 cases of coronary artery stenosis patients were 410,of which the left anterior descending artery（LAD） 188 branch（45.9%）,left circumflex branch（LCX） 106 branch（25.9% ）the right coronary artery（RCA） 104 branch（25.4% ）, the left main coronary artery 12（2.9% ）; stenosis for 50%-70% of 175（42.7%）, 70%-90% of a 203（49.5%）, 90%-100% of a 32（7.8%）. Conclusion The negative of myocardial perfusion imaging and coronary angiography and more narrow in the lack of physical activity, mild to moderate stenosis patients, single-vessel disease and the balance of the three patients.
