The diagnostic value of exercise load nuclear myocardial perfusion imaging for coronary heart disease

Objective To explore the diagnostic value of exercise load nuclide myocardialperfusion imaging for coronary heart disease .Method:A total of 117 suspected cases of coronaryheart disease were diagnosed using coronary angiography (CAG)results as the diagnostic criteria .Two types of examinations were performed:electrocardiogram treadmill activity test and exerciseload nuclide myocardial perfusion tomography,and the results were compared and analyzed .Compared with the CAG results,the sensitivity and specificity of the electrocardiogram treadmillactivity test in diagnosing coronary heart disease were 60%and 73%,respectively;The sensitivityand specificity of exercise load nuclide myocardial perfusion imaging in diagnosing coronary heartdisease are 87%and 69%,respectively.Conclusion:Compared with the electrocardiogram treadmillactivity test,exercise load nuclide myocardial perfusion imaging has high sensitivity and similarspecificity,and has important value in non-invasive diagnosis of coronary heart disease.
