From 1985 to 1987; we performed the treadmill exercise test on 206 patients who had been suffering from anterior chest pain; suspected angina pectoris.
Among the subjects; male to female ratio was 1.8:1; the mean age was 50 years old; and the most prevalent age group was 6th decade (36%). 89 cases revealed positive results(depression of ST segment > 1mm; shape of ST segment: horizontal or declined). In the positive group; 68 cases were showed more than 2.0mm of ST-segment depression; or could not finish stage 2 of Bruce protocol; which represent multiple-vessel disease. Depressed ST-segment showed any site of 12 leads; but the most common lead group was V5?6 (89%); and the next one was I; M. AVF (71%); and the least one was I; AVL (4%). The relationship between the degree of ST segment depression and the number of changed leads; showed positive correlation (p<0.01). During the test; no serious complication occured. In conclusion; we consider that the treadmill exercise test is a very useful; noninvasive and objective method to assess the ischemic heart disease.
