Abstract:
Objective:To detect the 3′-terminal 2′- O-methylation (2′Ome) modified microRNA-486-5p (miR-486-5p) levels in the serum of patients with coronary heart disease (CHD), and evaluate its clinical application value as a biomarker to assist the diagnosis of CHD. Methods:Seventy patients with CHD diagnosed at the Eastern Theater General Hospital from January 2021 to December 2022 and 60 age-and sex-matched healthy people undergoing health examination during the same period were selected for this retrospective case-control study. The Gensini score was calculated based on coronary angiography results, and patients in the coronary artery disease group was categorized into mild-to-moderate stenosis (40 cases) and severe stenosis subgroups (30 cases); Serum biochemical indexes, miR-486-5p and 2′Ome-miR-486-5p expression levels were compared between the CHD group and the healthy control group; correlation of biochemical indices, Gensini score and serum miR-486-5p and 2′Ome-miR-486-5p levels was assessed by using Spearman correlation analysis; and multifactorial logistic regression was used to analyze the impact of serum miR-486-5p and 2′Ome-miR-486-5p levels on CHD and the degree of coronary artery stenosis; evaluation of the diagnostic value of 2′Ome-miR-486-5p levels on the degree of coronary artery disease and coronary artery stenosis was achieved by using ROC curve.Results:Serum miR-486-5p and 2′Ome-miR-486-5p levels were significantly higher in CHD group than in the healthy control group [0.31 (0.17, 0.84) vs 0.21 (0.11, 0.49), Z=2.055, P<0.05; 2.30 (1.32, 5.40) vs 0.86 (0.55, 1.72), Z=5.840, P<0.05]; Serum 2′Ome-miR-486-5p expression levels were higher in both mild-moderate and severe stenosis subgroups than in healthy controls ( P<0.05), and serum 2′Ome-miR-486-5p levels were higher in the severe stenosis subgroup than in the mild-moderate stenosis subgroup [3.54(1.78, 5.44) vs 1.63(1.25, 4.07), Z=-2.053, P<0.05]. Both serum miR-486-5p and 2′Ome-miR-486-5p levels were positively correlated with the Gensini score ( r=0.277 and 0.479, respectively, P<0.05); multifactorial logistic regression analysis showed that serum 2′Ome-miR-486-5p level was an independent influence factor of the degree of coronary stenosis after adjustig for the effects of confounding factors such as age and sex ( OR=1.025, 95% CI 1.002-1.049, P<0.05). ROC curve analysis showed that the area under the ROC curve of serum 2′Ome-miR-486-5p levels for the diagnosis of CHD patients, mild to moderate and severe stenosis were 0.798, 0.752 and 0.859, with sensitivities of 91.4%, 92.5%, and 73.3%, and specificities of 56.7%, 51.7% and 81.7%, respectively, at the optimal cut-off (0.912, 0.863, 2.209). Conclusion:Serum 2′Ome-miR-486-5p level is increased in CHD patients and is an independent predictor of the severity of coronary artery stenosis, which can be used as a biomarker for the diagnosis of patients with CHD.
