Duke treadmill score
Risk stratification tool combining exercise duration, ST depression, and angina symptoms from treadmill stress testing.
Full Definition
The Duke treadmill score is a validated prognostic tool that combines three key variables from exercise stress testing: exercise duration in minutes, maximal ST-segment depression in millimeters, and presence of exercise-induced angina. The formula calculates a numerical score that stratifies patients into low, intermediate, or high-risk categories for cardiovascular events. This scoring system helps guide clinical decision-making regarding further testing, revascularization, and medical management in patients with suspected or known coronary artery disease.
Usage
Usage note: Capitalize 'Duke' as it refers to Duke University; express scores with appropriate positive or negative values.
