What is

Bruce treadmill test (protocol)

The Bruce treadmill test protocol is a widely used exercise stress test that assesses cardiovascular function and aerobic capacity. It's a standardised method that involves a gradual increase in workload through changes in speed and incline. The test typically consists of multiple stages, each lasting several minutes, with the intensity increasing as the test progresses. Key dimensions measured include exercise duration, maximum heart rate and blood pressure response. The test is commonly used in clinical and research settings to diagnose and monitor cardiovascular disease, evaluate exercise capacity and estimate VO2 max. By monitoring a patient's physiological response to exercise, healthcare professionals can identify potential issues and develop targeted interventions. This information can be used to inform treatment decisions and improve patient outcomes, making the Bruce treadmill test an important tool in cardiovascular assessment and management.

Scoring

The Bruce treadmill test can be scored using two main approaches: estimating VO2 max and assessing exercise-induced ischaemia.1. Estimating VO2 max: This method involves measuring the duration of exercise on the treadmill and using it to estimate aerobic capacity. VO2 max is calculated using a formula that incorporates exercise duration, typically yielding a value in millilitres per kilogram per minute (mL/kg/min).2. Assessing exercise-induced ischaemia: This approach involves monitoring electrocardiogram (ECG) changes, blood pressure, and symptoms during exercise. The test is stopped if the patient experiences severe symptoms, significant ECG changes, or reaches a predetermined heart rate. The results help diagnose coronary artery disease and assess cardiovascular risk.
