Abnormal Longitudinal, Base-to-Apex Myocardial Perfusion Gradient by Quantitative Blood Flow Measurements in Patients With Coronary Risk Factors

Abstract

The abnormal longitudinal, base-to-apex perfusion gradient observed during dipyridamole MBF suggests the presence of a functional and/or structural alteration of the coronary circulation associated with coronary risk factors, possibly reflecting developing coronary atherosclerosis or preclinical CAD.
