Background Cardiovascular disease (CVD) has remained the leading cause of death in the last 15 years and is one of the main health problems in Saudi Arabia. Our study aims to assess the prevalence of different CVD risk factors and correlate them among King Faisal Cardiac Center patients in King Abdul-Aziz Medical City in Jeddah, Saudi Arabia. Methods We conducted a cross-sectional study using a convenient sampling technique. Data were collected by interviewing adult patients admitted to King Faisal Cardiac Center and diagnosed with hemodynamically stable cardiac disease. We excluded patients with multiple medical conditions that contribute to acute mental disorders. The sample size was calculated to be 200 patients. Results Overall, 163 patients completed the survey. The majority of the participants (49.1%) were between 46-65 years of age, males, non-smokers, and had more than 11 children. Diabetes was found to be the most common risk factor (66.3%). Most participants had mild to moderate anxiety (63.8%) and depression (66.9%). Most of the patients (51.5%) have a high 10-year risk of developing CVD, followed by moderate and low risk (33.1% and 15.3%, respectively). In our study, a high 10-year risk of CVD was significantly associated with age between 46-80 years with a p-value=0.002, male gender with a p-value=0.007, cigarette smoking with a p-value=0.031, and diabetes with a p-value=0.035. Conclusion The study demonstrated a high prevalence of the following CVD risk factors: age, male gender, immobility, obesity, diabetes, dyslipidemia, and hypertension. In addition, a significant association was found between high 10-year risk of CVD and age, gender, smoking, number of children, and diabetes with a p-value<0.05. No significant association was found in the other risk factors such as obesity, body mass index (BMI), immobility, caregiver, dyslipidemia, depression, and anxiety.
