Correlation Between SCORE2-Diabetes and Coronary Artery Calcium Score in Patients with Type 2 Diabetes Mellitus: A Cross-Sectional Study in Vietnam

(1) Background: The SCORE2-Diabetes model has been developed as an effective tool to estimate the 10-year cardiovascular risk in patients with diabetes. Coronary computed tomography angiography (CCTA) and its derived Coronary Artery Calcium Score (CACS) are widely used non-invasive imaging tools for assessing coronary artery dis-ease (CAD). This study aimed to evaluate the correlation between CACS and SCORE2-Diabetes in patients with T2DM. (2) Methods: A cross-sectional study was conducted from October 2023 to May 2024. We included patients aged 40 to 70 years with T2DM who underwent a coronary multislice CT scan due to atypical angina. The cor-relation between CACS and SCORE2-Diabetes was analyzed using Spearman’s rank correlation coefficient. (3) Results: A total of 100 patients met the inclusion criteria, in-cluding 71 males and 29 females, with a mean age of 61.9 ± 5.4 years. The differences in CACS and SCORE2- Diabetes among different degrees of coronary artery stenosis were statistically significant (p < 0.05). A statistically significant but weak positive correlation was observed between CACS and SCORE2-Diabetes across all risk categories, with Spearman’s rank correlation coefficients ranging from 0.27 to 0.28 (p < 0.01). (4) Conclusion: Despite the weak correlation between CACS and SCORE2-Diabetes, the combination of these two tools may enhance cardiovascular risk assessment in diabetic patients.
