Introduction: Coronary heart disease is considered as the biggest cause of death in Saudi Arabia. Twenty–three percent of the population dies because of (CHD) (20.877). The study‘s aim is to evaluate the heart symptoms and CPR knowledge of Alhassa adult‘s residents.

Method:  A cross sectional analytic and descriptive survey based study among

Population in Hofuf, KSA. In October 2013, online–form questionnaires were published in the social network and the filled questionnaires were filtered to meet the selection criteria.

Results: The mean age of the sample was 29–years, most of them were females (53, 3%) (Table1), and most of the respondents were highly educated (75, 3 %). Only (19, 7%) had CPR training courses and only (6.0%) had seen someone experiencing heart attack. The percentage of the respondents that had a relative or friend with heart disease was (43%).

The respondents’ knowledge about CPR was insufficient. When asked twelve questions about CPR, only (34.9%) were able to give 8 right answers or above whilst (50.7%) could only give 5 right answers or less.

Our findings do not suggest any demographic differences in CPR knowledge, but they show a significant gender difference in knowledge of heart attack symptoms.

Conclusion: Therefore, CPR outreach programs might be needed in AL–HASSA to improve the population‘s knowledge and confidence in performing CPR and recognizing heart attack symptoms and thus reducing CHD mortality rate.
