OBJECTIVES: The treadmill exercise eletrocardiography(ECG) is the most commonly used non-invasive method in the evaluation of patients with chest pain. But the accuracy of treadmill exercise ECG in detecting the coronary artery disease(CAD) is still controversial. To improve the accuracy of the treadmill exercise test, exercise treadmill score(ETS) based on exercise duration, degree of ST deviation, and treadmill anginal index during treadmill exercise ECG has been used. METHODS: The authors calculated ETS by simple equation(total exercise duration-5 X maximal ST-segment deviation during or after exercise-4 X treadmill angina index) and analyzed coronary angiograms of 173 patients(mean age '55.5 +/- 8.7, male: female=2.7: 1) who underwent treadmill exercise ECG and coronary angiography in Chonnam University Hospital from January, 1990 through March, 1993. RESULTS: 1) The studied subjects were subdivided into 3groups according to ETS. Group A(high risk, ETS
