The Usefulness of Exercise Stress Echocardiography in Diagnosis of Coronary Artery Disease

Abstract

BACKGROUND
To evaluate the usefulness of exercise echocardiography in diagnosis of coronary artery disease and to compare it with exercise ECG test. METHOD: We performed exercise test in 48 patients who suffered from angina-like chest pain, according to the modified Bruce protocol. During exercise, we observed the ECG changes and recored the images of left ventricular wall motion before and after exercise on the video tape. The echocardiogram were digitally stored and displayed in a format that allowed simultaneous analysis of rest and stress images. Newly developed left ventricular wall motion abnormalities were determined as positive findings. RESULTS: The feasibility of exercise echocardiography was 75%. The sensitivity and specificity fo exercise ECG test was 67% and 89%. The sensitivity and specificity of exercise echocardiography was 85% and 100%. The sensitivity of ECG and echocardiography was 50%(7 of 14) and 78.6%(11 of 14) in those with one-vessle disease and 84.6%(11 of 13) and 92.3%(12 fo 13) in those with multi-vessle disease. CONCLUSION: Exercise stress echocardiography was very usefull method for detecting the coronary artery disease especially in single vessle disease. And it had much higher accuracy than the stress ECG test.
