Abstract

Introduction: Coronary artery calcification (CAC) is considered a critical risk factor for cardiovascular events. With advancements in multislice computed tomography (MSCT), the assessment of coronary artery calcification using the Agatston score has become increasingly accurate. Objective: To investigate factors associated with the degree of coronary artery calcification on MSCT scans. Methods: A cross-sectional descriptive study was conducted on 111 patients with chest pain who underwent MSCT and coronary angiography at the Vietnam National Heart Institute. Administrative, clinical, and paraclinical data were collected. The Agatston score was calculated and analyzed using linear regression to assess its association with risk factors. Data were processed using SPSS 16.0 and Stata 12. Results: The mean age of patients was 64.9 ± 8.6 years, with 68.5% being male. Hypertension, dyslipidemia, and smoking were observed in 77.5%, 44.1%, and 49.6% of patients, respectively. The mean Agatston score was 110.3 (range: 8.9–287). The study found a significant linear correlation between age and the Agatston score in the overall group (regression coefficient: 11.39, p < 0.005). In the acute coronary syndrome group, the Agatston score was associated with Pro-BNP, LVEF, and age, while no correlation was found in the stable angina group. Conclusion: Coronary artery calcification was positively associated with age and certain factors in the acute coronary syndrome group. The study highlights the role of the Agatston score in cardiovascular risk assessment and suggests further research with a larger sample size.
