Risk stratification for coronary artery disease and mortality based on exercise treadmill test


\[ DTS = Exercise Time \hspace{0.1cm}–\hspace{0.1cm} (5 \times Max ST) \hspace{0.1cm}–\hspace{0.1cm} (4 \times Angina) \]

More Info

The Duke Treadmill Score (DTS) is a point system to predict mortality and probability of coronary artery disease based on treadmill ECG stress testing.

Patients are categorized based on Duke treadmill score as follows:

DTSRisk category
>=+5Low risk
+4 to -10Moderate risk
<= -11High risk

VD = Vessel Disease;  LM = Left Main
