Summary
The Duke Treadmill Score (DTS) accurately estimates diagnostic and prognostic risk in women, performing equally well as in men for stratifying risk and better for excluding coronary artery disease.
Area of Science:
- Cardiology
- Diagnostic Testing
- Risk Stratification
Background:
- Treadmill testing accuracy for diagnosing chest pain in women is debated.
- The diagnostic and prognostic utility of the Duke Treadmill Score (DTS) in women remains unestablished.
Purpose of the Study:
- To evaluate the diagnostic and prognostic capabilities of the DTS in a female cohort.
- To compare the DTS performance between women and men.
Main Methods:
- The DTS was assessed in 976 women and 2,249 men who underwent treadmill testing and cardiac catheterization.
- Diagnostic accuracy and prognostic value were determined for both genders.
Main Results:
- Significant differences in DTS, coronary artery disease (CAD) prevalence, and mortality were observed between genders.
- The DTS provided significant prognostic information beyond clinical predictors for both sexes.
- The DTS demonstrated superior performance in women for excluding significant and severe CAD compared to men.
Conclusions:
- The DTS effectively stratifies women into diagnostic and prognostic risk categories.
- The DTS is a valuable tool for assessing cardiovascular risk in women, with enhanced performance in disease exclusion.
