Background: İn coronary artery disease, the positive contribution of the presence of coronary collateral circulation to the course of the disease is known. As for the factors that trigger the formation of collateral circulation and interactions at the cellular level, no satisfactory results have yet been reached. Studies on this issue will also pave the way for potential treatment opportunities in the future. The aim of this study is to try to determine the relationship between coronary collateral circulation and elabela and apelinergic system.Methods: This is a cross sectional study. Totally 150 subjects were included the study. Demographic data, laboratory test data, and comorbidities were collected from the hospital data. Welch, One Way Anova, Chi-Square, and Kruskal-Wallis H tests were used for comparison of the groups. Games-Howell, Tukey HSD, and Dunn tests were used for post-hoc analysis where necessary.Results: Evaluating the differences between the groups in terms of the parameters examined. Looking at which groups the differences arise from; it was observed that the statistically significant difference observed for elabela, HDL-C, NT-ProBNP, LVEF and HS-C-Reactive protein was between all groups separately.Conclusions: In this study, we aim to reveal a positive relationship between the development of coronary collateral vessels and apelinergic systems. Our results indicated that Elabela protein could be evaluated as a potential agent for treatment.
