Abstract
Background:
Collateral arteries provide an alternative source to myocardium resulting from ischemia due to occlusive coronary artery disease and may help preserve myocardial function in the case of coronary artery disease (CAD)[1]. Although the collateral development is so important, its pathophysiology has not been fully elucidated. Until now, there is no study investigating the relationship between Fibroblast growth factor-21(FGF-21) and coronary collateral.
Objective:
This study aims to investigate the pathophysiology of coronary collateral development.
Methods:
In our study, which we planned as a case control, 60 consecutive patients with ≥90 stenosis in at least one large coronary artery as a result of coronary angiography (CAG) and 30 patients with normal coronary angiography were included in the study cross-sectional. Demographic, echocardiographic and laboratory data were recorded. Coronary collateral circulation was evaluated using the Rentrop–Cohen method [2]. FGF-21 levels were measured in all individuals.
Results:
In the analysis, no significant difference was observed between the two groups in basic biochemical parameters other than HDL (p>0.05 for all). FGF-21 level was found to be statistically significantly higher in the patient group compared to the control group (p:0.003). Also, FGF-21 level was found to be statistically significantly higher in the good collateral circulation group to the poor collateral circulation group (p:0.006). Univariate and multivariate logistic regression analysis was performed to predict the presence of collateral. We found that FGF-21(p=0.006), C-reactive protein (p=0.020) predicted the presence of collateral independently.
Conclusion:
Collateral formation and cardiac prognosis are closely related. Our study is the first to investigate the relationship between collateral formation and FGF-21. Our study showed that FGF-21 level is an independent predictor of collateral formation. In addition, there was a significant difference between bad and good collateral formation in terms of FGF-21 levels.
