摘  要:【目的】评价腺苷负荷试验心肌灌注显像对冠心病的诊断价值及腺苷负荷试验的安全性。【方法】收集2011年2月至2013年2月在本院疑诊冠心病患者75例,均行腺苷负荷^99m Tc-甲氧基异丁基异腈(MIBI)心肌灌注断层显像,腺苷按体重0.14 mg/(kg ·min)通过输液泵静脉双通路给药,并对心肌灌注断层显像图作定性分析,所有患者1~3 d后行冠状动脉造影检查。【结果】75例患者中冠脉造影正常32例;1支以上狭窄≥50%者43例,其中单支病变14例,双支病变16例,三支病变13例;共检出病变血管85支,累及左前降支(L AD )38支,左回旋支(LCX)28支,右冠状动脉(RCA)21支,左主干(LM)2支。腺苷负荷心肌灌注显像诊断冠心病的灵敏度为88.3%(38/43),特异性为87.5%(28/32),准确性为88.0%(66/75),阳性预测值为90.5%(38/42),阴性预测值为84.8%(28/33)。对病变冠脉诊断灵敏度为75.9%(63/83),特异性93.7%(133/142),准确性87.1%(196/225),阳性预测值为94.0%(63/67),阴性预测值为84.2%(133/158)。对单支、双支、3支血管病变诊断的灵敏度分别为50%(7/14)、62.5%(10/16)和92.3%(12/13)。对各病变血管检测灵敏度为:LAD 86.1%(31/36),LCX 55.6%(15/27),RC A 85%(17/20)。腺苷不良反应总发生率为80%(60/75)。【结论】腺苷负荷试验心肌灌注显像诊断冠心病敏感性及特异性均较高,并且不良反应轻微,是协助诊断冠心病安全有效的方法。Objective To evaluate the accuracy and safety of adenosine stress myocardial perfusion imaging in the diagnosis of coronary heart disease .[Methods]Totally 75 patients suspected as coronary heart disease in our hospital from Feb .2011 to Feb .2013 received adenosine ^99m Tc-methoxy isobutyl isonitrile(MIBI) myocardial perfusion imaging .According to the weight of 0 .14 mg/(kg · min) ,adenosine was administrated by infusion pump and venous double pathway .Myocardial perfusion imaging spectrum was used for quantitative analysis .Coronary angiography was performed in all patients after 1~3 days .[Results]Of 75 patients ,32 patients had normal coro-nary angiography ,and 43 patients had more than one stenosis vessel≥50% in which 14 cases were single vascular lesion ,and 16 cases were double vascular lesion ,and 13 cases were three vascular lesion .There were 85 diseased vessels .Involvement was found in 38 left anterior descending arteries(LAD) ,28 left circumflex arteries(LCX) ,21 right coronary arteries(RCA) and 2 left main(LM) .The sensitivity ,specificity ,accuracy ,positive predictive value and negative predictive value of adenosine stress myocardial perfusion imaging in the diagnosis of coronary heart disease were 88 .3% (38/43) ,87 .5% (28/32) ,88 .0% (66/75) ,90 .5% (38/42) and 84 .8% (28/33) ,respectively .The sensitivity ,specificity ,accuracy ,positive predictive value and negative predictive value of adenosine stress myocardial perfusion imaging in the diagnosis of coronary artery lesion were 75 .9% (63/83) ,93 .7% (133/142) , 87 .1% (196/225) ,94 .0% (63/67) and 84 .2% (133/142) ,respectively .The sensitivity of adenosine stress myo-cardial perfusion imaging in the diagnosis of single ,double and 3 vascular lesions were 50% (7/14) ,62 .5% (10/16) and 92 .3% (12/13) ,respectively .The sensitivity of adenosine stress myocardial perfusion imaging in the diagnosis of LAD ,LCX and RCA were 86 .1% (31/36) ,55 .6% (15/27) an
