Duke Treadmill Score Calculator For Coronary Heart Disease

The Duke Treadmill Score Calculator evaluates a patient's cardiac risk and prognosis by analyzing exercise stress test results, including exercise time, ST-segment changes, and functional capacity. It helps clinicians assess cardiovascular health and make informed decisions regarding patient care.

What is Duke Treadmill Score Calculator

The Duke Treadmill Score is a cardiovascular risk assessment tool that helps predict the risk of cardiac events during exercise stress testing.

• It combines exercise duration, ST segment changes on the electrocardiogram (ECG), and exercise-induced angina to calculate a numerical score.
• The score is used to classify patients into low, moderate, or high-risk categories for future cardiac events.
• The Duke Treadmill Score can assist healthcare professionals in making informed decisions regarding patient management and treatment strategies.

What is Coronary Artery Disease

Coronary Artery Disease (CAD) is a cardiovascular condition.

• It results from the buildup of plaque in the coronary arteries, causing them to narrow and restrict blood flow to the heart.
• CAD can lead to angina (chest pain) and increase the risk of heart attack and other cardiovascular events.
• Risk factors include smoking, high blood pressure, high cholesterol, diabetes, obesity, sedentary lifestyle, and family history of heart disease.

If a patient is at high risk of heart disease or already shows symptoms, doctors may use various tests to diagnose Coronary Artery Disease (CAD). One such test is the exercise stress test, which assesses the patient's cardiovascular health.

 

The Duke Treadmill Score Calculator helps provide essential information during this evaluation, assisting in determining the patient's risk and potential treatment options.

How to Calculate Duke Treadmill Score

Here are the basic steps to calculate Duke Treadmill Score.

• Enter Your Exercise (min)
• Enter Max ST-segment deviation (mm)
• Enter Angina Index Condition
• Calculate Duke Treadmill Score (DTS)

Duke Treadmill Score Formula

The Duke score equation is as follows:

Duke score = exercise – 5 * ST-segment dev. – 4 * TAI

where:

• exercise is the duration of exercise expressed in minutes.
• ST-segment dev. is the maximal net ST-segment deviation expressed in millimeters.
• TAI is the Treadmill Angina Index, that we can describe as follows:

Duke Treadmill Score Calculator Example

Here is a basic Duke Treadmill Score Calculator Example.

• Let's use the Duke treadmill score calculator for another patient named Raj.
• Raj took a Duke treadmill test, and he exercised for 10 minutes.
• He didn't experience any pain during the test, and his maximal net ST-segment deviation was equal to 1.2 mm.

The Duke score will be calculated as follows:

• Duke score = exercise – 5 * ST-segment dev. – 4 * TAI
• Duke score = 10 min – 5 × 1.2 mm – 4 × 0
• Duke score = 10 - 6 - 0
• Duke score = 4

In this example, Raj's Duke score is 4. The Duke score ranges from -25 to +15, with higher scores indicating a lower risk of cardiovascular events. Since Raj's score is 4, it suggests a relatively moderate risk.

However, it's important to interpret the Duke score in the context of other clinical factors and consult with a healthcare professional for a comprehensive assessment of cardiovascular health and potential treatment options.

Duke Treadmill Score Calculator Benefits
