Abstract

With the goal of improving the prediction of restenosis after percutaneous transluminal coronary angioplasty (PTCA), we evaluated the usefulness of the Delta ST/Delta heart rate (HR) index derived from serial exercise treadmill tests. Exercise treadmill tests were performed by 125 patients with single-vessel coronary artery disease before and several days after PTCA, and lust before followup angiography 3 to 12 months later. Simple HR-adjusted indexes of ST-segment depression during exercise (Delta ST/Delta HR index) were derived. We compared the usefulness of the increase in Delta ST/Delta HR index at follow-up over the value obtained several days after PTCA for prediction of restenosis with that of a positive exercise treadmill test and a positive thallium scintigram at follow-up. At follow-up, 47 of the 125 patients showed restenosis. The Delta ST/Delta HR index increased in 43 of 47 patients in the restenosis group and in 18 of 78 patients without restenosis (p< 0.0001). Separate analysis of each criterion revealed the followingrespective values for sensitivity, specificity, and positive and negative predictive valves for prediction of restenosis: increased Delta ST/Delta HR index at follow-vp: 91%, 77%, 70%, and 94%; positive exercise treadmill test: 83%, 65%, 59%, and 86%; and positive thallium scintigram: 79%, 78%, 69%, and 86%. The increased Delta ST/Delta HR index had a significantly (p < 0.05) higher sensitivity than the positive thallium scintigram and a significantly (p < 0.01) higher specificity than the positive exercise treadmill test. An increased Delta ST/Delta HRindex at follow-up identifies subgroups of patients who are at high risk for restenosis after PTCA. (C) 1996 by Excerpta Medica, Inc.
