Introduction: Coronary artery disease is most common heart disease among people in this world. It is a preventable lifestyle disease. Certain life style changes will influence the risk factors of developing coronary artery disease in sedentary workers and heavy workers. Objectives: the primary objective of the study was to compare the risk factors of coronary artery disease among sedentary and heavy workers. Methodology: A quantitative approach and non-experimental comparative case control was adopted for the study. Total 120 samples (60 sedentary workers and 60 heavy workers) selected by convenient sampling technique. Data were collected by interview method using structured questionnaire method. The collected data were analyzed by frequency and percentage distribution. Results: The results showed that there was a significant association between the risk factors of CAD among sedentary workers such as BMI (χ2=8.58, p=0.014), types of work (χ2=45.50, p=0.001), age (χ2=18.99, p=0.001) and exercise (χ2=0.00, p=0.001). And there was a significant association between the risk factors of CAD in case among sedentary and heavy workers such as monthly family income (χ2=6.74, p=0.034), alcohol (χ2=12.43, p=0.006), coffee (χ2=19.47, p=0.001) and mode of transportation (χ2=34.35, p=0.001) and there was a significant association between the risk factors of CAD in control among sedentary and heavy workers such as BMI (χ2=19.36, p=0.001), alcohol (χ2=20.26, p=0.001), smoking (χ2=8.11, p=0.044), coffee (χ2=30.97, p=0.001), and mode of transportation (χ2=30.00, p=0.001). Conclusion: The study concluded that the risk factors of coronary artery disease is more common in sedentary workers than heavy workers. Being aware of the risk factors will help the peoples become aware of their chances of developing coronary artery disease and therefore will encourage them to adopt healthy lifestyle.
