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