Objective: To investigate the correlation between ischemia-modified albumin (IMA) levels and coronary collateral circulation (CCC) in patients with chronic total occlusive (CTO).
Methods: Coronary angiography was performed in the Department of Cardiology, Zhongnan Hospital of Wuhan University from 2017-08 to 2019-02 to identify 128 patients with CTO lesions in at least one major coronary artery. According to the Rentrop evaluation criteria, the degree of CCC formation was divided into the poor CCC formation group (Rentrop0-1 grade,n=69) and the good CCC formation group(Rentrop2-3 grade,n=59). The IMA level of the patients was measured using an albumin-cobalt binding assay. The general data, routine blood panel, total bilirubin (TBIL), blood lipids, uric acid (UA), left ventricular ejection fraction (LVEF) and other indicators of the patients were recorded and analyzed while assessing the patients' blood vessel occlusion.
Results: The proportion of platelet count and diabetes in the poor CCC group was higher than that in the good CCC group (P<0.05). The ratio of ischemia-modified albumin and total bilirubin in the poor CCC group was lower than that in the good CCC group (P<0.05). Multivariate logistic regression analysis showed that ischemia-modified albumin was positively correlated with CCC formation [OR=1.190,95% CI(1.092-1.297),P<0.001], while diabetes was negatively correlated with CCC formation [OR=0.285,95% CI(0.094-0.864),P<0.05]. Ischemic modified albumin predicted good formation of CCC according to the ROC curve, and the area under the ROC curve was 0.769(95% CI:0.686-0.851，P＜0.001); the optimal cut-off value was 63.35 KU/L, and the sensitivity was 71.2%,specificity is 71%.
Conclusion: The IMA level is closely related to good formation of CCC. Higher IMA levels can be used as an effective predictor of good CCC formation in patients with CTO.
