Abstract：ObjectiveTo investigate the diagnostic value of transesophageal atrial pacing stress test combined with treadmill exercise test in male patients with coronary disease. MethodsEightytwo male patients with suspected coronary artery disease underwent coronary arteriography and transesophageal atrial pacing stress test combined with treadmill exercise test 1 month before or after coronary arteriography. The degree and range of coronary artery stenosis assessed in diameter method was compared between results of coronary arteriography and transesophageal atrial pacing stress test combined with treadmill exercise test. ResultsWith the result of coronary arteriography as a criterion, transesophageal atrial pacing stress test combined with treadmill exercise test had a sensitivity of 72.9% in diagnosing coronary disease, a specificity of 52.6%, a positive predictive rate of 90.4% and a negative predictive rate of 78.7%. It also revealed that in the combined method, the more the coronary artery stenosis leads were, the earlier ST segment depressions appeared with deeper depression degree and longer duration(P<0.001). Patients with positive results of coronary arteriography and negative ones in the combined method were mostly single vessel diseased or slightly diseased.ConclusionsThe transesophageal atrial pacing stress test combined with treadmill exercise test is simple, easy to practice and noninvasive, which can increase the diagnostic rate of coronary disease and preliminarily estimate the degree of coronary artery stenosis.
