To the Editor: In regard to the article by Rozanski et al. (Sept. 1 issue),* one would hope that a negative radionuclide stress test discouraged performance of coronary angiography in at least some of their patients. Consequently, the incidence of true-negative results of exercise ventriculography in their population remains unknown. Since specificity equals (true-negative results)/(true-negative plus false-positive results), any assumptions about declining specificity of exercise ventriculography cannot be made from their data or study design. The observed specificity of exercise ventriculography in their earlier series may have overestimated the true specificity of the test (though this is by no means.
