目的:探讨腺苷负荷心肌核素显像对冠心病的诊断价值。方法:94例拟诊冠心病患者均行冠状动脉造影,腺苷负荷99mTc-MIBI心肌灌注显像、静息心肌显像检查,比较腺苷负荷心肌核素显像与冠状动脉造影结果。结果:冠状动脉造影检查阳性62例中,腺苷负荷心肌核素显像阳性50例。32例冠状动脉造影示无明显狭窄者中,腺苷负荷心肌核素显像阴性24例。腺苷负荷心肌核素显像诊断冠心病的敏感性和特异性分别为80.6%和75.0%。2,3支病变血管腺苷负荷心肌核素显像阳性率高于单支血管病变(P<0.05)。结论:腺苷负荷心肌核素显像诊断冠心病敏感性、特异性较高。
Objective: To investigate the diagnostic value of adenosine stress myocardial imaging for coronary heart disease. Methods: Ninety-four patients with suspected coronary heart disease underwent coronary angiography, myocardial perfusion imaging with 99mTc-MIBI adenosine load and resting myocardial imaging, and adenosine stress myocardial imaging and coronary angiography were compared. Results: Coronary angiography in 62 cases of positive, adenosine load myocardial imaging positive in 50 cases. 32 cases of coronary angiography showed no stenosis, adenosine stress myocardial imaging 24 cases were negative. The sensitivity and specificity of adenosine stress myocardial imaging for the diagnosis of coronary heart disease were 80.6% and 75.0%, respectively. The positive rates of myocardial adenosine load and myocardial angiography in 2,3 vessels were higher than those in single vessels (P <0.05). Conclusion: Adenosine load myocardial imaging in the diagnosis of coronary heart disease sensitivity, high specificity.
