Background: Nonalcoholic fatty liver disease (NAFLD) is one of the most prevalent chronic liver diseases worldwide and is closely associated with metabolic syndrome and insulin resistance. Growing evidence suggests a link between NAFLD and cardiovascular diseases, independent of traditional risk factors. Coronary computed tomography angiography (CCTA) is a reliable noninvasive method for evaluating coronary artery disease (CAD) and identifying high-risk coronary plaque characteristics. However, data regarding the association between NAFLD and high-risk coronary plaques remain limited, particularly in Iran. This study aimed to evaluate the prevalence of NAFLD in patients with high-risk coronary plaques detected by CCTA. Methods: In this cross-sectional study, 200 patients who underwent CCTA for the evaluation of coronary plaques in outpatient clinics or the emergency department of Golestan Hospital in ahvaz ,1403 ,were enrolled. Demographic data, including age, sex, weight, and body mass index (BMI), along with clinical characteristics and cardiovascular risk factors such as hypertension, diabetes mellitus, dyslipidemia, smoking status, and medical history were collected. Patients with a history of alcohol consumption or known liver disease were excluded. NAFLD was assessed based on imaging findings. Statistical analyses were performed to compare variables between patients with and without NAFLD. Results: The mean age of patients with NAFLD was 57.89 ± 9.72 years, compared with 55.77 ± 8.97 years in patients without NAFLD, with no statistically significant difference. The prevalence of NAFLD was slightly higher in women than men; however, this difference was not significant. Patients with NAFLD had a significantly higher mean weight than those without NAFLD (85.21 ± 12.12 kg vs. 79.62 ± 11.85 kg; p = 0.001). Additionally, the prevalence of NAFLD increased significantly with higher BMI categories, particularly in obese individuals. Conclusion: Age and gender were not significantly associated with NAFLD prevalence in patients with high-risk coronary plaques. In contrast, increased body weight and higher BMI, especially obesity, were independently associated with a higher risk of NAFLD in this population. |
