How Well Does Radionuclide Dipyridamole Stress Testing Detect Three-Vessel Coronary Artery Disease and Ischemia in the Region Supplied by the Most Stenotic Vessel?

Abstract

These results have important implications for interventional cardiologists who perform angioplasty on the most stenotic vessel, because the regions supplied by these vessels may not be the most ischemic. Furthermore, dipyridamole stress imaging may significantly underestimate the number of patients with substantial three-vessel coronary artery disease when qualitative imaging is done.
