The Usefulness of Supine Bycycle Stress Echocardiography for Evaluationg Coronary Artery Disease: Comparision with Exercise Electrocardiography

： ： exercise echocardiography are widely used for evaluating coronary artery disease. In comparison with posttreadmill exercise echocardiography, supine bicycle stress echocardiography (SBSE has the advantage of imaging during stress and at peak exercise and ischemic wall motion abnormalities at the time of imaging are more frequent and more extensive. Therefore, SBSE is a valuable tool for evaluation of coronary artery disease. This study was designed to provide the hemodynamic changes during exercise and compare the sensitivity, specificity and predictive values of the wall motion abnormalities of supine bicycle stress echocardiography during peak exercise with those of 12-lead electrocardiography (ECG during exercise for evaluating coronary artery disease. Materials and Methods：One hundred patients for evaluation of possible coronary artery disease performed supine bicycle stress echocardiography. This study consisted of 51 patients who underwent coronary arteriography. Significant coronary artery disease was defined as the presence of ≥50% or ≥75% diameter reduction determined by magnified electronic caliper measurements, compairing the accuracy of supine bicycle stress echocardiography to that of 12-lead exercise ECG. Results：1 Fifty-one patients (31 men, 20 women underwent both supine bicycle stress echocardiography and coronary arteriography, the results were age (54.5±9.8 years, heart rates (68±12 vs 124±22 beats/min, systolic blood pressure (130±23 vs 175±32
