Abstract:
Objective To investigate the relationship between the expression of plasma miRNA-195 in pa-tients with severe coronary artery stenosis and its coronary collateral circulation. Methods One hundred and nine-ty patients with selective coronary angiography in our hospital from March 2000 to May 2017 were enrolled,who were divided into poor collateral circulation group(n = 90)and good collateral circulation group(100 cases)ac-cording to the Rentrop classification.Plasma miRNA-195 and VEGF levels were compared between the two groups. The relationship between plasma miRNA-195 and VEGF was analyzed,and also the relationship between plasma miRNA-195 and Gensini points.Results(1)Plasma miRNA-195 and VEGF levels in good collateral circulation group were significantly higher than those in poor collateral circulation group(P<0.05).(2)There was a positive correlation between plasma miRNA-195 and VEGF in patients with coronary heart disease(r=0.628,P=0.022). (3)There was a positive correlation between plasma miRNA-195 and Gensini score in patients with coronary heart disease(r = 0.765,P = 0.013). Conclusion MiRNA-195 may be involved in the production of neovasculariza-tion by regulating VEGF in the formation of collateral circulation in patients with severe coronary artery stenosis, which can be used as a biomarker for predicting the formation of collateral circulation for clinical reference.
