Performance Diagnostics is a cardiovascular stress test that uses treadmill, bicycle exercise or arm ergometry with electrocardiography (ECG) and blood pressure monitoring.
Treadmill stress testing is indicated for diagnosis and prognosis of cardiovascular disease, specifically CAD. Contraindications have been outlined in guidelines from the American College of Cardiology (ACC) and the American Heart Association (AHA).
Treadmill Stress Testing
Exercise capacity is reported in terms of estimated metabolic equivalents of task (METs). The MET unit reflects the resting volume oxygen consumption per minute (VO2) for a 70-kg, 40-year-old man, with 1 MET equivalent to 3.5 mL/min/kg of body weight.
In the standard Bruce protocol, the starting point (ie, stage 1) is 1.7 mph at a 10% grade (5 METs). Stage 2 is 2.5 mph at a 12% grade (7 METs). Stage 3 is 3.4 mph at a 14% grade (9 METs). This protocol includes 3-minute periods to allow achievement of a steady state before workload is increased.
The modified Bruce protocol has 2 warm up stages, each lasting 3 minutes. The first is at 1.7 mph and a 0% grade, and the second is at 1.7 mph and a 5% grade. This protocol it is most often used in older individuals or those whose exercise capacity is limited by cardiac disease.
The Bruce protocol has larger increments between stages than do other protocols, such as the Naughton, Weber, and Asymptomatic Cardiac Ischemia Pilot (ACIP) study protocols, all of which start with less than 2 METs at 2 mph and increase in 1- to 1.5-MET increments between stages.
