Detection of Coronary Artery Disease by First Pass Radionuclide Exercise Testing
Anatomic lesions of a coronary artery do not always equate with the presence of a functional abnormality in the area of myocardium formerly supplied by the stenosed vessel . Even the muscle supplied by a totally occluded coronary artery may have adequate blood supply from collateral vessels. Although the myocardial blood supply in such cases may be adequate to meet the myocardial oxygen demand at rest, the blood supply may not be able to increase adequately to meet the increased myocardial oxygen demands during exercise stress. As a result, left ventricular dysfunction ensues [2,3].
