In order to evaluate the diagnostic value of exercise treadmill score (TS), which is a prognostic index calculated by using ST segment depression, angina and exercise duration, for identification of high-risk coronary artery disease, 284 patients who underwent exercise TI-20 1 SPECT and coronary angiography were studied. Patients with TS>5 were defined as the low-risk group (group ı , n=94, mean age 51.2±9.2yrs), those with- ılKeywords: Coronary disease, exercise tesıs, risk stratification
