Aim: Coronary artery disease is one of the most frequent causes of mortality and morbidity seen all over the world. In definite diagnosis of the atherosclerotic coronary artery stenosis, coronary angiography is used. In this study, ad­ditional contribution of the effort stress testing together with myocardial perfusion scintigraphy, which are nonin­vasive tests, to choose patients to coronary angiography. Materials and Methods: 101 patients (47 men, 54 wom­en; mean age: 55 ± 10.95 year) were included into the study. In all patients 99m Tc-MIBI myocardial perfusion scintigraphy was performed following physiological ef­fort on treadmill. Patients in whom coronary angiography were performed in 1 month before or after scintigraphic evaluation were included into the study. Results: In 55% of patients having positive effort stress testing, 82% of patients having suspicious and 29% of patients with negative test results atherosclerotic narrow­ing in coronary arteries were detected by angiography. Whereas, in 66% of patients had ischemic myocardial perfusion scintigraphic findings and 12% of patients with normal scintigraphy, angiography revealed coronary ar­tery stenosis. Conclusion: In diagnosis and follow-up of coronary ar­tery disease, effort stress testing and myocardial perfu­sion test are used. If findings of these tests are evaluated together, accuracy of the tests will be increased.
