Abstract

Objective: This study aims to evaluate the correlation between abdominal fat parameters and coronary artery stenosis as observed through computed tomography (CT). Material and methods: A cross-sectional descriptive study was conducted on patients suspected of having coronary artery disease (CAD) at Tam Anh General Hospital, Ho Chi Minh City, from July 2023 to May 2024. These patients were indicated for coronary CT angiography, and also had an abdominal CT scan within 1 month. The correlation between abdominal fat parameters (VAT, SAT, VAT/SAT) and coronary artery stenosis was analyzed. Results: The study included 207 patients, with an average age of 58.03 ± 11.15 years, ranging from 35 to 85 years old. Obstructive coronary artery disease (O-CAD) was found in 69/207 patients, accounting for 33.3%, while non-obstructive coronary artery disease (NO-CAD) was found in 138/207 patients, accounting for 66.7%. Males constituted the majority of the study population. The analysis showed that factors such as age, dyslipidemia, hypertension, blood glucose, HbA1c, VAT, and VAT/SAT ratio were related to coronary artery stenosis. Anthropometric fat indices such as waist circumference, BMI, total fat, and subcutaneous fat were not associated with coronary artery stenosis. Conclusion: The study indicates that, besides traditional cardiovascular risk factors, VAT and the VAT/SAT ratio are closely associated with the risk of coronary artery stenosis.
