Prognostic value of the duke treadmill score in asymptomatic women.
The Duke Treadmill Score ( DTS ) has been shown to predict mortality in women who have symptomatic heart disease , but its ability to do so in asymptomatic women is unknown , as is its comparative advantage to exercise capacity . We investigated whether a decreased DTS is associated with increased mortality in a prospect i ve cohort of 5,636 asymptomatic women . A symptom-limited exercise treadmill test using Bruce 's protocol was performed at baseline . DTS was calculated using exercise time , exercise-induced angina , and ST-segment depression . Exercise capacity was measured in METs . Deaths and cause of death were identified from 1992 to 2000 . After adjusting for the Framingham Risk Score , the risk of death decreased by 9 % for each unit increase in DTS and by 17 % for every 1-MET increase ( p < 0.001 ) . Those who had a DTS < 5 ( moderate or high risk ) had hazard ratios for death and cardiac death that were 2.2 and 2.5 times greater , respectively , than did those who had a DTS > or = 5 ( low risk ) , after adjusting for Framingham Risk Score ( p < 0.001 ) . Receiver-operating characteristic curves for the DTS model and the exercise capacity model were not significantly different . In conclusion , we have demonstrated that , although the DTS is an independent predictor of mortality and cardiac mortality in asymptomatic women , it does not appear to be a better predictor than exercise capacity alone . The role of ST-segment changes and symptoms with stress testing in asymptomatic women does not provide additional prognostic information
