The Relationship Between Coronary Collateral Circulation and Visceral Fat
Journal Title: E Journal of Cardiovascular Medicine - Year 2021, Vol 9, Issue 1
Abstract
Objectives: Collateral circulation is assumed to prevent myocardial ischemia in healthy subjects and in patients with coronary artery disease. Visceral adipose tissue is an active component of total body fat, which holds some biochemical characteristics that have impact on several normal and pathological processes in the human body. In this study, we investigated the relationship between visceral fat ratio and coronary collateral circulation (CCC). Materials and Methods: Totally 148 patients with stable angina pectoris were recruited to the study and all patients’ heights and weights were recorded after the coronary angiography. The study subjects were divided into two groups as those between 1 and 9, and those >10 by classifying their visceral fat ratio with bioelectrical impedance analysis method. Patients were classified as poor CCC group (grade 0 and 1) and good CCC group (grade 2 and 3) based on the Rentrop’s classification of CCC. Results: In the analysis in accordance with collateral classification, visceral fat percentage (13.7±4.7 versus 10.1±4.0, p=0.01) and body mass index (28.2±2.4 versus 27.3±2.3, p=0.040) were found significantly higher in the poor collateral group. Diabetes mellitus was significantly higher in patient with high visceral fat ratio. In multivariate logistic regression analysis for collateral growth, visceral fat percentage [odds ratio (OR): 0.740, %95 confidence interval (CI): 0.602- 0.909, p=0.040] and coronary stenosis percentage (OR: 1.220, %95 CI: 1.070-1.390, p=0.003) were found meaningful, independent from the other factors. In ROC analysis, increase in visceral fat level decreased collateral growth with 72.7% sensitivity and 58.5% specificity. Conclusion: The increase in visceral fat seems an independent factor for poor collateral development.
