Abstract ObjectiveTo evaluate the diagnostic value of treadmill exercise testing(TET) in detecting silent myocardial ischemia(SMI).MethodsA total of 200 patients, with no history of angina but STT changes,were detected by TET and CAG. The sensitivity,specificity and accuracy of SMI ,diagnosed by TET,were calculated. Results SMI identified TET with a sensitivity of 72.1%,specificity of 78.8% and accuracy of 75.5%.ConclusionTET could evaluate the SMI accurately,and it was one of the ideal means of noninvasive examination.
