Abstract

Objective: The study aims to describe the characteristics and evaluate some factors related to 4 on 640-slice computed tomography images in patients suspected of coronary artery disease. Materials and methods: A cross-sectional study was conducted on 125 patients suspected of coronary artery lesions who presented to Hoa Hao-Medic Can Tho General Hospital and underwent multi-slice computerized tomography scan from June 2023 to December 2023. Results: In terms of general characteristics, males accounted for the majority (57.6%), with a mean age of 61.1 ± 9.9 years. Two-thirds of the subjects had hypertension (with two-thirds having poorly controlled blood pressure), and one-third had diabetes mellitus. Additionally, 40.8% and 16.0% of patients had a family history of coronary artery disease and dyslipidemia, respectively. On CT images, 75% of patients had moderate to severe coronary artery stenosis, while 25% had mild stenosis, with stenosis over 50% in 3 branches being the highest proportion at 30.4%. In the moderate to severe stenosis group, distribution was mainly in the LAD branch at 59.2%, followed by RCA and LCx at 54.4% and 43.2%, respectively. Moderate to severe stenosis in the left main coronary artery accounted for only 5.6%. Multivariate logistic regression analysis revealed that age ≥ 60 and poorly controlled blood pressure were statistically significant factors associated with coronary artery stenosis, with OR = 18.4 (95% CI: 1.9-176.9), p=0.012 and OR = 57.7 (95% CI: 5.9-567.4), p=0.001, respectively. Conclusion: 640-slice computerized tomography scan in patients suspected of coronary artery disease helps detect most cases of coronary artery stenosis, even at mild levels. Advanced age and poorly controlled blood pressure were statistically significant factors associated with moderate - severy coronary artery stenosis.
