Based on the ACC/AHA guidelines, the pretest<unk>  of underlying coronary<unk><unk>  (CAD) can be classified into low (less than 10%-20%),<unk>  (between 20%-80%) and<unk><unk>  (more than 80%-90%). All<unk>  with<unk>  to<unk><unk>  of CAD need to undergo exercise stress testing to stratify the risk of subsequent coronary events and hence determine the appropriate diagnostic and therapeutic interventions. Bruce protocol and DUKE score are widely adopted methods for exercise stress testing. The exercise capacity, clinical, hemodynamic and electrocardiographic responses must be considered while interpreting the results of exercise treadmill test.
