The search for new biomarkers and therapeutic targets remains a key issue in the cardiovascular field. miRNA-22 and miRNA-133a, which are highly expressed and play an important regulatory role in the cardiovascular system, have been fully demonstrated that they are deeply involved in various pathophysiological processes of cardiovascular diseases. In this study, the expression level of miRNA-22/133a in ACS patients and its correlation with the severity of coronary lesions were further studied. Objective: To analyze the correlation between the expression levels of serum miRNA22 and miRNA133a and the severity of coronary lesions in patients with acute coronary syndrome (ACS), and their predictive value for the prognosis of ACS patients. Methods: In this study, 187 patients with ACS who were hospitalized in the Cardiovascular Department of Taizhou People’s Hospital from January 2023 to February 2024 were continuously collected. General information, past medical history and laboratory test indicators of the subjects were collected. 5 ml blood samples were collected from the subjects’ right radial artery or femoral artery before coronary angiography, and total RNA was extracted. Real-time fluorescent quantitative PCR (RT-qPCR) was used to obtain the relative expression level of serum miRNA-22/133a. Results: (1) Comparison of the relative expression level of serum miRNA-22/133a between different groups: Compared with the control group, the relative expression level of serum miRNA-22/133a in the ACS group was significantly increased, with statistical significance (P 0.05). (2) Correlation analysis between the relative expression level of serum miRNA-22/133a and Gensini score: Serum miRNA-22/133a (β = 0.274, P β = 0.378, P < 0.001) was positively correlated with Gensini score. (3) Logistic regression of ACS: serum miRNA-22 OR value was 1.433, 95% CI:1.089~1.641, P = 0.011, indicating that serum miRNA-22 was a risk factor for the onset of ACS. The OR value of serum miRNA-133a was 1.877, 95% CI: 0.934~2.356, P = 0.013, indicating that serum miRNA-133a was a risk factor for the incidence of ACS. (4) ROC curve analysis: evaluation of the efficacy of serum miRNA-22/133a in diagnosing coronary artery stenosis ≥ 50%. The Area under the curve (AUC) and 95% Confidence interval (CI) were 0.846 (0.759~0.933) and 0.808 (0.720~0.895), respectively. Combined detection (AUC (95% CI): 0.892 (0.823~0.961)) was superior to the separate detection of serum miRNA-22 and miRNA-133a. Conclusion: (1) Serum miRNA-22/133a levels in ACS patients were significantly increased;(2) The level of serum miRNA-22/133a was positively correlated with the severity of coronary lesions;(3) Serum miRNA-22/133a were risk factors for ACS.
