ABSTRACT
BACKGROUND AND OBJECTIVES:
The Duke treadmill exercise score (DTS) has been used to stratify patients with coronary artery disease into low-, moderate-, and high-risk groups. To determine the coronary angiographic and myocardial scintigraphic correlates of these scores, we have compared the degree of risk assessed by the DTS and with those obtained by angiography and SPECT. SUBJECTS ANDMETHODS:
The subjects were classified into low risk (DTS >or= 5), moderate risk ( 4 > DTS >or= -11) and high risk (DTS 10 abnormal segments, group 3 (n=41) had one vessel disease and less than 5 abnormal segments, and group 2 (n=41) included the remaining subjects. Based on the DTS, 37 (36%) were in the low-risk, 44 (43%) in the moderate risk, and 21 (21%) in the high risk groups. In the low-risk DTS patients, 32.4% were in group 1, 35.2% in group 2 and 32.4% in group 3. In relation to the subjects with moderate risk DTS, there were 9, 16 and 55% in groups 1, 2 and 3, respectively. Whereas, there were 19, 24 and 57% in groups 1, 2 and 3 with high risk DTS subjects, respectively.CONCLUSION:
Although considerable overlap exists, the degree of risk assessed from the angiography and SPECT findings were different from those by DTS. We suggest that patients classified into the low-risk DTS group may have extensive coronary artery disease, or myocardial perfusion SPECT abnormalities, whereas patients in the high-risk DTS group may be normal, or have mild coronary artery disease or mild SPECT abnormalities.
