Abstract

To prove that the exercise stress test (EST) has low sensitivity in assessment of coronary flow reserve after bypass surgery (ACBP) compared to the symptomatic patients for coronary artery disease (CAD) without surgical treatment. Methods: 670 patients performed exercise stress test in the EST unit of the SHC "Filip II" in the period from November 2004 to March 2006. The first group included 450 patients who were symptomatic for CAD, not surgically treated. In the second, there were 35 patients that had ACBP. The assessment of coronary flow reserve was made by Bruce protocol. To confirm the accuracy of the results for the both groups of patients with positive EST selective coronarography was performed. Results: From 450 patients' sympthomatic for CAD with no surgical treatment, 87 (19.3%) had positive EST and 28 (6.2%) had borderline EST The coronarography findings of the patients that resulted positive from EST showed sensitivity of EST >75%. In the second group of patients with ACBP, 21 (60%) had positive EST, 14(40%) had negative from the total number of 35 patients. Coronarography was performed in all patients who had positive EST and in 3 (14%) patients the coronarography findings were positive. Conclusion: EST has low sensitivity in assessment of coronary flow reserve In patients with ACBP compared with It'S sensitivity in the group of patients with sympthomatic CAD without bypass surgery.
