The relationship between triglyceride/high-density lipoprotein cholesterol ratio and the functional significance of coronary lesions

Aims: Have shown that triglycerides (TG) are an independent risk factor for cardiovascular disease (CVD). Dyslipidemia characterized by low high-density lipoprotein cholesterol (HDL-C) has been shown to be associated with symptoms of coronary artery disease (CAD). In studies, the TG/HDL-C ratio has been found to be strongly associated with parameters indicative of the severity of coronary disease. In this study, we aimed to investigate whether the TG/HDL-C ratio is associated with the functional significance of moderate coronary artery lesions. Methods: A total of 102 consecutive patients, 72 male and 30 female, who underwent measurement of fractional flow reserve (FFR) due to moderate coronary stenosis (quantitative coronary analysis 40-70%) on angiography were included in the study. An FFR value ≤0.80 was accepted for hemodynamic significance. Results: Among the 102 patients included in the study, it was determined that 52 (50.9%) had significant functional stenosis. Left ventricular ejection fraction of Group II was lower than Group I (60 (55-62.5) vs. 55(50-60), p=0.006). The male patient ratio was higher in Group II, but the difference between the two groups was not significant (68% and 77%, respectively, p=0.072). Univariate and multivariate logistic regression analysis showed that TG/HDL-C (OR=1.278, 95% CI=1.078-1.514, p=0.005) was an independent determinant of significant functional stenosis. ROC analysis revealed that the TG/HDL-C value was 3.89 and provided 64% specificity and 61.5% sensitivity in predicting hemodynamically significant coronary artery stenosis. Conclusion: Elevated TG/HDL-C values are associated with the functional significance of angiographically moderate coronary artery stenosis.
