Coronary artery disease is one of the most prevalent causes of increasing mortalitiy in current time. Early detection of such dreadful condition by a non-invasive test like exercise treadmill test, is a much-required option to prevent future complications like myocardial infarction. The aim of this study was to find out how different the predictability of simple treadmill score in comparison to other treadmill scores namely the well-known Duke treadmill score and Cleveland clinic score. In a cross-sectional analytical study of total 130 individuals with stable angina were included according to criteria set before the study. The treadmill scores of these patients were calculated and compared to coronary angiogram findings where coronary artery angiograms were done according to clinical need. Simple treadmill test had similar predictability for coronary artery disease when we compared it with much-applied Duke Treadmill Test and Cleveland Clinic Score- which is currently used for mortality prediction. Receiver Operator Characteristics (ROC) Curve showd all scores had around 0.7 area under the curve (AUC) which is highly statistically significant (p<0.0001) though simple treadmill score in females has higher sensitivity (92.3%). Simple treadmill score can be considered to exclude female patients from undergoing invasive investigation as it has higher sensitivity than other currently practiced treadmill scores i.e., Duke treadmill score.
