“…Most of the studies correlating exercise performance with coronary arteriography have addressed themselves to such parameters in patients with normal resting electrocardiograms;4 6,8 some investigators have included patients with abnormal resting tracings, 8' 10-12 and others" 13 have reported on hemodynamic parameters correlated with coronary arteriograms as related to postexercise electrocardiograms. However, only one abstract'4 has appeared attempting to relate the anatomic site of disease with the STST performance.…”

SUMMARYTwo hundred patients had submaximal treadmill stress tests (STSTs) and selective coronary arteriography performed within 2 months of each other. An attempt was made to assess the predictability of disease isolated to any given coronary vessel by performance on the treadmill. This was not possible for disease isolated to the right coronary, the left anterior descending, the circumflex branch of the left coronary, or a combination of right coronary and circumflex arteries. Eleven patients had disease in the left main coronary artery; all had associated disease of some other branch as well. One of these patients had a negative submaximal treadmill stress test but was unable to reach 90% of his maximum predicted heart rate. The remaining 10 patients had positive STSTs. Patients with 26-50% narrowing of any branch had treadmill results similar to those with 51-75% narrowing. There was a large number of patients with single-vessel disease in the study and most of the negative STSTs occurred in this group. Nevertheless, within this group no one vessel gave a higher incidence of positive STSTs than any other. It is concluded that (1) (1) specific branch of the coronary tree involved; (2) severity of luminal narrowing, i.e., the maximal narrowing of any branch of the coronary tree; and (3) extent of vascular involvement, i.e., number of branches narrowed.

Background. The presence or absence of baseline diagnostic Q waves has been believed to compromise the accuracy of standard exercise electrocardiography in identifying severe coronary artery disease (three-vessel and/or left main disease); therefore, a retrospective analysis was performed using a personal computer data base of exercise test responses and cardiac catheterization results to evaluate this premise, and follow-up was performed to observe how Q waves and/or severe coronary disease impacted on survival.

“…Heart rates up to 85 or 90% of anticipated maximum have been induced, resulting in an improved correlation between positive electrocardiographic tests and severe coronary disease in the angiogram. 35 These tests are too cumbersome and time consuming for office diagnosis, and the two-step test must be interpreted with caution, i.e., with awareness of its diagnostic limitations in the individual patient. The more strenuous exercise tests are being used for comparative preand postoperative studies to provide an objective evaluation of the effectiveness of coronary bypass procedures.…”
