Three kinds of stress methods in the diagnosis of coronary artery disease

Objective: To evaluate the diagnostic value of three kinds of methods: exercise electrocardiography(EE),dobutamine stress echocardiography(DOBE) and ATP stress echocardiography (ATPE) in coronary artery disease(CAD) according to coronary angiography. Methods: There are fifty-six patients who were examined with coronary angiography, EE, DOBE and ATPE. The date of coronary angiography were compared with the three kinds of methods. Results: The sensitivity in the diagnosis of CAD with the three kinds of methods were 77%,83% and 80%,respectively.The specificity were 81%,88% and 96%, respectively. The accuracy were 79%,86%,88%, respectively. Conclusions: The three kinds of methods had high sensitivity and specificity, and reached high diagnostic accuracy. They were lower cost and effective metheds.
