Prognostication in the Patient with Coronary Artery Disease: Preliminary Results of Radionuclide Cineangiographic Studies
Radionuclide cineangiography during exercise has frequently been demonstrated to be of value in the diagnosis of coronary artery disease (Borer et al. 1977, 1979, 1980). However, the quantitative nature of the technique lends itself readily not only to the detection of disease, but also - by permitting determination of the extent of change in left ventricular ejection fraction from rest to maximal exercise — to assessment of the functional severity of ischemia in a given individual (Borer et al. 1977, 1978, 1979, 1980; Kent et al. 1978). It seems intuitively reasonable that prognosis of the individual patient should depend directly on the functional severity of ischemia from which he or she suffers. Parenthetically, it is increasingly clear that coronary arteriography, as it is currently performed and analyzed, provides only a general guide to the severity of ischemia (Borer et al. 1979).
