The additive prognostic value of tests done in a hierarchical order for the detection of coronary artery disease (CAD) is not always known. The principal goal of this study, therefore, was to assess the incremental prognostic value of data obtained in succession (clinical, exercise stress testing, 201Tl imaging, and coronary angiography) in patients with suspected CAD. A second goal was to develop models for determining prognosis based on results of these tests and to test the clinical validity of these models in unrelated patients.
