CVD predisposition risk varies according to age, gender, education, socioeconomic factors, and place of residency. In addition, CVD risk factors include physical inactivity, sedentary lifestyle, saturated fatty acid high diet, smoking, and stress. Aim: This is a systematic review study that aims to determine the effect of mindful mediation, physical activity, and diet on CVD in SA. Materials and Methods: This is a systematic electronic search method in Google scholar, PubMed, and Medline. Papers collected are papers that have been published since 2015. The search uses the following keywords: (Cardiovascular disease OR physical activity OR Physical inactivity OR meditation OR diet) AND Saudi Arabia. Data were extracted from each study through a narrative summary of each study. Results: Forty papers collected from 2015 to 2022 were included in the narrative study. Physical activity, diet, and mindful meditation are among the factors that can reduce the risk of development of CVD or severity of disease in patients with a CVD. Conclusion: This systematic review emphasized risk factors like physical inactivity, poor diet, and low level of awareness among Saudis and CVD Saudi patients. The findings show the role of physical activity, mindful meditation, and diet in reducing the onset or severity of cardiovascular disease.展开更多
