OBJECTIVE: To elucidate knowledge of coronary artery disease (CAD) risks factors and coronary intervention in adult students of Karachi East. To calculate the mean knowledge score about CAD risk factors among them.
METHODS: A multi center crossectional study was conducted in Universities and colleges of Karachi East from April-September 2005. Questionnaires were distributed to 200 adult students of different non-medical universities and colleges. The questionnaire contained assessment of knowledge of risk factors on CAD and awareness about coronary angiography. Those belonging to medical colleges and universities were excluded from the study. Knowledge was assessed as a continuous variable. Risk factors for CAD were taken as categorical variables.
RESULTS: The mean age of students was 20 yrs +/- 2.2 years and 62% were females. The mean score of knowledge about risk factors of CAD was 11.47 +/- 2.37. Sixty percent students thought that heart diseases are the number one cause of death in our population. Twenty five percent students graded smoking as the top most risk factor for CAD. Twenty five percent students refused to quit smoking for CAD prevention. Forty eight percent students correctly defined coronary angiography. Eighty five percent students thought that cost is the major hindrance in getting timely treatment. Knowledge of fifty percent students was based on personal and family experience of heart disease.
CONCLUSION: Students graded smoking as the topmost risk factor for CAD and cost as the major hindrance in getting timely treatment for heart disease. Only half of the students were aware about coronary angiography. The mean knowledge score among them was above the median score but not up to the mark
