Aim: This study aims to determine the perception of adult patients towards the importance of prevention of coronary artery diseases (CAD) in order to raise awareness on the risk of CAD. Method: 80 adults between 18 - 40 years old were enrolled in the out-patient department at a private hospital. The awareness and perception of the importance of preventing CAD were assessed using a questionnaire. Result: The level of perception on the importance of prevention of CAD was quite good. 75% of the subjects (n = 60) recorded good level of perception meaning they are aware of the importance of prevention of CAD. 22.5% of the subjects (n = 18) recorded a satisfactory level of perception while only 2.5% of the subjects (n = 2) recorded a poor level of perception towards the importance of prevention of CAD. Majority of the subjects had good perception on importance of a balanced diet, exercise and active lifestyle. Conclusion: In conclusion it can be said that although people are aware of the risk posed by CAD, recommendations such as proper health teachings and guide lines are still required to ensure that the community is able to understand the risk and take preventive measure in order to reduce the risk of obtaining the risk of heart disease.
