Long-term Follow-up of Patients With Positive Exercise Test Without Angina in a Referred Population
Exercise testing has proved to be a valuable tool for identifying patients with coronary artery disease (CAD). Frequently, however, patients with CAD have ischemic ECG responses to exercise testing without experiencing angina. Relatively few studies [1–6] have dealt with the long-term prognosis of these patients, and it is still not clear whether the absence of anginal symptoms is of prognostic importance or not. The purpose of our study was to evaluate the clinical outcome of patients with positive exercise test (PET) without angina during the test, and to compare this outcome with one or more variables derived from the test.
