In this study, we aimed to investigate the relationship between serum homocysteine levels and coronary collateral development. Material and Method: Consecutive 176 patients, with acute coronary syndrome and chronic total occlusion, were divided into two groups according to coronary collateral development. Rentrop 0 and 1 were regarded as group I and Rentrop 2 and 3 as group II. Results: Plasma homocysteine levels were 18.2±7.0 ?mol/L in the group I and 15.7±5.1 ?mol/L in the group II. Univariate logistic regression analysis showed that mean platelet volume and homocysteine were associated with poor coronary collateral. Multivariate logistic regression analysis showed that homocysteine level was independently associated with poor coronary collateral circulation (OR 1.069 [95% CI 1.012-1.130]; p=0.018). Conclusion: In this study clearly demonstrates that high serum homocysteine level is associated with poor collateral development in patients with acute coronary syndrome.eninfo:eu-repo/semantics/openAccessGenel ve Dahili TıpKimyaTıbbiKalp ve Kalp Damar SistemiArticle32929910.32322/jhsm.657326485692
