- Abstract
Recognizing the important physiological relationship between the heart and exercise, Dr Robert Arthur Bruce undertook research that revolutionized the way physicians approach cardiac disease. His contributions to exercise physiology and cardiology have shaped many concepts used today in clinical practice. He is best known for developing a protocol for the exercise treadmill test known as the Bruce protocol. Because of its universality, reproducibility, and practicality, the protocol remains one of the most widely used methods for diagnosing ischemic heart disease. Patients commonly start exercising on a treadmill set at 1.7 miles per hour and a 10% grade, and increase to a maximum speed of 6.0 miles per Dr Luong is a cardiology resident in the Division of Cardiology at the University of British Columbia.

Bruce, father of exercise cardiology The exercise treadmill test known as the Bruce protocol continues to play an important role in diagnosing coronary artery disease in intermediate-risk patients. hour and a 22% grade. The aim of testing is to detect the presence of coronary artery disease by looking for electrocardiogram changes during times of stress. The sensitivity of exercise treadmill testing is estimated to be 70% and the specificity to be 80%. These values range broadly depending on multiple factors, including the definition of a positive test result. The strongest predictor of survival found on exercise treadmill testing is exercise capacity. Treadmill testing can also be combined with imaging modalities to further increase sensitivity and specificity, making it one of the first tests considered when coronary artery disease is suspected in a patient.
