The aim of the study was to evaluate the quantitative indices of abdominal adipose tissue according to the data of multispiral computed tomography (MSCT) in patients with ischemic heart disease (IHD).
Patients and Methods: 88 patients with a verified diagnosis of ischemic heart disease were included in the study. The comparison group consisted of 32 patients without ischemic heart disease. All patients of these groups underwent MSCT at the level of L4-L5 lumbar vertebrae. In a transverse section of 1 mm thick, the area of the abdominal adipose tissue, as well as its visceral (VAT) and subcutaneous (SAT) components, was measured at the level of L4—5 intervertebral disc. The evaluation of the volume of abdominal adipose tissue and its components was carried out on a 20 mm thick transverse section. In addition, all the patients were calculated the body mass index and the ratio of the circumference of the waist to the hip circumference (WC / HC).
Results: the body mass index (BMI) in the comparison groups did not differ significantly. The group of patients with IHD showed significantly higher values of WC / HC than the control group. The prevalence of obesity in terms of the VAT area in the group of patients with IHD was 70.4%, in the comparison group — 43.8%, in terms of the VAT volume in the group of patients with IHD — 78.4%, in the control group — 56.25% with reliable differences. The prevalence of obesity according to morphometric data obtained with the use of MSCT significantly exceeds the prevalence of obesity verified with the use of BMI in both groups. Using a volumetric index of visceral adipose tissue allows the most reliable determination of a group of patients with visceral obesity.
Conclusion: multispiral computed tomography has been proved to be the most reliable method in assessing obesity, in comparison with the routine anthropometric methods. The volumetric evaluation of VAT is not only as good as the quantitative estimation based on the VAT area, but also allows to increase the diagnostic capabilities of identifying a group of patients with cardiometabolic risk associated with obesity.
