AIM: Coronary collateral circulation (CCC) is crucial during an acute ischemic attack. Evidences showed that omentin-1 exhibited remarkable antiatherogenic effects and ischemia-induced revascularization. The aim of this study was to investigate the relationship between plasma omentin-1 levels and CCC in patients with ≥90% angiography-proven coronary occlusion. METHODS: 142 patients with ≥90% luminal diameter stenosis in at least one major epicardial coronary artery were recruited. Among them, 79 patients with Rentrop 0-1 grade were classified into the poor CCC group and 63 patients with Rentrop 2-3 grade were included into the good CCC group. The association between plasma omentin-1 levels and CCC status was assessed. RESULTS: Plasma omentin-1 level was significantly higher in patients with good CCC than those with poor CCC (566.57±26.90 vs. 492.38±19.70 ng/mL, p=0.024). Besides, omentin-1 was positively correlated with total cholesterol (TC), high-density lipoprotein, and gensini score but inversely with hyperlipidemia and body mass index (all p values＜0.05). Multivariate regression analysis indicated that omentin-1 [odds ratio (OR)=1.002, 95% confidence interval (CI): 1.000-1.004, p=0.041)], TC, the number of the diseased vessels, a higher frequency of left circumflex artery and right coronary artery, chronic total occlusion, and gensini score remained as the independent predictors of good CCC. CONCLUSION: Higher plasma omentin-1 level was associated with better CCC development. Our findings suggest that omentin-1 may be an alternative marker for adequate CCC in patients with ≥90% coronary occlusion.
