Study on correlation between circulating exosome miR-485-3p and STYX expression with onset of premature coronary heart disease
Objective To investigate the correlation between the expression of circulating exosome miR-485-3p and STYX with the risk of premature coronary heart disease.Methods A total of 50 inpatients with early onset coronary heart disease diagnosed by coronary angiography or CT angiography (CTA) in Af-filiated Puyang Municipal People's Hospital of Xinxiang Medical College from August to December 2023 were selected as the study group and 50 patients with excluded coronary artery disease by examination during the same period were included in the control group.The general clinical data of the two groups were collected,the plasma exosome miR-485-3p and STYX levels were detected.The degree of coronary arterial lesions in the pa-tients of the study group was evaluated by the Gensini score.The Spearman correlation analysis was used to analyze the relationship between plasma exosome miR-485-3p and STYX with LDL and Gensini score.The re-ceiver operating characteristic (ROC) curve was used to analyze the diagnostic value of plasma exosome miR-485-3p and STYX in the diagnosis of premature coronary heart disease.The multivariate logistic regression was used to determine the independent risk factors for premature coronary heart disease.Results Compared with the control group,the family history of coronary heart disease,smoking history,LDL and plasma exo-some miR-485-3p level in the study group were increased,the plasma STYX level was decreased and the differences were statistically significant (P<0.05);the Spearman correlation analysis showed that miR-485-3p was positively correlated with LDL (r=0.546) and Gensini score (r=0.485),and negatively correlated with STYX (r=-0.576).STYX was negatively correlated with LDL (r=-0.389) and Gensini score (r=-0.531).The ROC curve showed that the area under the curve of miR-485-3p,STYX and their combination in the diagnosis of premature coronary heart disease was 0.821 (95％CI:0.736-0.906),0.850 (95％CI:0.772-0.927) and 0.899 (95％CI:0.837-0.960) respectively.Conclusion The expression of circulating exosome miR-485-3p in premature coronary heart disease is up-regulated and the expression of STYX is down-regulated,the both are closely related to the degree of coronary artery lesion,which could be used as the po-tential biomarkers for the diagnosis of premature coronary heart disease.
