Abstract

Background: Coronary artery disease is the leading cause of myocardial ischemia and heart attack. Screening, early detection of coronary artery disease, and timely intervention help improve the quality of life in the patients at risk of myocardial ischemia, heart attack, and could reduce mortality rates. Objective: To investigate the clinical characteristics and imaging findings of coronary artery disease patients using 160-detector row computed tomography (CT) scanner at An Giang Central General Hospital from 2022 to 2023. Materials and methods: A cross-sectional descriptive study was conducted on 157 patients with coronary artery diseases who were examined and treated at An Giang Central General Hospital from February 2022 to May 2023. The patients were diagnosed with coronary artery stenosis using 160 detector row computed tomography angiography and the findings were reassessed using angiographic images of coronary arteries taken percutaneously. Results: In terms of clinical characteristics, the percentages of patients with chest pain symptoms, hypertension history, and diabetes were 77.1%, 66.2%, and 28.7%, respectively. 27.4% of patients had a habit of alcohol consumption, and 27.4% were smokers. The percentage of the patients with a heart rate ≥70 beats per minute before computed tomography was 5.7%. In terms of morphological characteristics, the percentages of the patients with Agatston coronary artery calcification scores of 0, 1-99, and 100-399 were 23.3%, 21.2%, and 55.5%, respectively. The number of narrowed coronary artery branches was 326 branches in 157 patients. Among them, 30.1% had righ coronary artery (RCA) stenosis 7.7% had left main (LM) stenosis, 39.2% had left anterior descending (LAD) stenosis, and 23% had left circumflex (LCX) stenosis. The percentage of patients with coronary artery stenosis ≥50% was 84.1% and ≥70% was 72.6%. Conclusion: The most common clinical characteristic in patients who come for examination and treatment at An Giang Central General Hospital was chest pain. The most frequently affected coronary artery branch was the left anterior descending (LAD) artery, accounting for 39.2%. The proportion of coronary artery stenosis ≥50% were above 80%.
