Abstract 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 per-fusion 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 val-ue 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) ,respective-ly .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 diag-nosis of LAD ,LCX and RCA were 86 .1% (31/36) ,55 .6% (15/27) and 85% (17/20) ,respectively .The total in-cidence rate of adverse reaction of adenosine was 80% (60/75) .[Conclusion]Adenosine stress myocardial perfusion imaging in the diagnosis of coronary heart disease has high sensitivity ,specificity and mild adverse reaction ,so it is a safe and effective method in the assistant diagnosis of coronary heart disease .
