Numerous risk factors contribute to cardiovascular diseases. Identifying individuals at high risk and ensuring they receive appropriate treatment can prevent premature deaths. This study aimed to "determine cardiovascular risk factors and some clinical parameters in patients admitted to the cardiac surgery intensive care unit." Methods: This study employed a cross-sectional design and was conducted on 109 patients admitted to the cardiac ICU of a central Tehran hospital. Samples were selected using convenience sampling based on inclusion criteria. Data were collected using a researcher-developed questionnaire and analyzed using SPSS version 25 with statistical tests. Results: The average age of the participants was 61.05±8.5 years. The majority of the sample was male (73.3%). The prevalence of diabetes and hypertension in the patients was 66.1% and 45.9%, respectively. The average BMI of the patients (25.9±3.6) was above the normal range. The mean blood glucose (153.26±36.65), cholesterol (151.7±36.2), triglycerides (135.85±51.9), kidney enzymes, and arterial blood gases were within acceptable ranges. Conclusion: Risk factors for cardiovascular diseases (particularly high weight and obesity, diabetes, and hypertension) are prevalent in patients undergoing cardiac surgery. Accordingly, planning and education are recommended to control and reduce cardiovascular disease risk factors in these patients. https://aacc.tums.ac.ir/index.php/aacc/article/view/1228
