Prognostic importance of exercise electrocardiography in patients with suspected microvascular disease
Background Coronary microvascular dysfunction (CMD) is associated with a poor prognosis but is difficult to diagnose non-invasively. In a recent paper, ST-segment depression on exercise-ECG was found to have a very high positive predictive value (PPV) for CMD in a highly selected group of patients. Objectives In the present study of chest pain patients, we used myocardial perfusion single photon e
