Using non-invasive methods for evaluating myocardial ischemia in assessment of the functional significance of intermediate coronary artery stenoses in patients with chronic ischemic heart disease

Key points of using non-invasive methods for evaluating myocardial ischemia (exercise electrocardiogram, stress echocardiography, single photon emission computed tomography and myocardial perfusion imaging with stress-test) in clinical practice to determine the functional significance of intermediate coronary artery stenoses (50-70% of the vascular lumen) are discussed in the review.
