Cardiovascular diseases (CVDs) are the primary contributors to mortality and morbidity on a global scale. The aim of this study is to examine knowledge, attitude and practices of the general public regarding CVDs in Saudi Arabia. This is a cross-sectional survey study that was conducted in Saudi Arabia to examine KAP of the general public regarding CVDs between January and February 2024. There were 605 participants in total enrolled in this study. The mean knowledge score for the study participants was 7.1 (2.5) out of 11 (64.5%)
which indicates moderate level of knowledge of CVD. A considerable proportion of participants (61.5%) report engaging in vigorous physical activity for a minimum of 30 minutes per day throughout the week, including activities like running, lifting large loads, or drilling. In terms of knowledge, there is no significant difference between males and females across gender categories (odds ratio = 0.92, P = .603). Within the age group category, those between the ages of 24 and 30 (odds ratio = 0.44, P <
.002) and 31 and 40 (odds ratio = 0.39, P <
.002) demonstrate noticeably diminished probabilities of possessing superior knowledge in comparison to those between the ages of 18 and 23. In relation to marital status, the odds of possessing superior knowledge are considerably lower for married individuals (odds ratio = 0.43, P <
.002), divorced individuals (odds ratio = 0.39, P = .003), and widowed individuals (odds ratio = 0.11, P = .004) in comparison to singles. The survey found moderate level of awareness of cardiovascular diseases and strong recognition of preventive measures including physical activity and a healthy diet. There are gaps in CVD symptom knowledge. Participants are typically favorable about CVD prevention and willing to adopt healthy lifestyles. Decision-making recommendations include targeted teaching efforts on symptom awareness, physical activity, and healthy diets. Further research is needed to determine how educational interventions improve knowledge across demographic groups. Longitudinal studies could also evaluate lifestyle treatments for CVD risk reduction.
