Key result
Exercise treadmill testing using a combination of exercise-induced chest pain and ST-segment depression yielded a significantly higher diagnostic accuracy for coronary artery disease (86.7%) compared to ST-segment depression alone (53.7%).

May improve treadmill test interpretation for CAD; leaves open prospective validation before practice change.
Introduction Exercise treadmill test (ETT) is one of the most used means in evaluation of coronary artery disease (CAD). Since the first medical treadmill designed to diagnose heart and lung disease was invented by Dr. Robert Bruce and Wayne Quinton at the University of Washington in 1952, it became the golden criteria in diagnosing CAD till coronary angiography (CAG) came

Mao et al. (2012) conducted an observational in Coronary Artery Disease (n=142). Exercise treadmill test (chest pain combined with ST-segment depression) vs. ST-segment depression alone was evaluated on Diagnostic accuracy rate for coronary artery disease (confirmed by coronary angiography) (p=<0.05). Exercise treadmill testing using a combination of exercise-induced chest pain and ST-segment depression yielded a significantly higher diagnostic accuracy for coronary artery disease (86.7%) compared to ST-segment depression alone (53.7%).
