Serum miRNAs expression was detected with real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR). The levels of plasma D-dimers were determined by detection with an enzyme-linked immunosorbent assay (ELISA). The receiver-operator characteristic (ROC) curve was used for evaluating the diagnostic accuracy of the studied miRNAs.Results: According to the Wells score, 42 of the 52 AECOPD patients were unlikely to have APE (≤ 4 points), whereas the remaining 10 (> 4 points) were likely to have APE. There were 4 cases (4/13 30.8%) in the AECOPD combined with APE group with a Wells score of > 4 points. The expression levels of miR-1233 and miR-134 in the serum were considerably upregulated in the AECOPD+APE group compared with the AECOPD group and the stable COPD group (P< 0.05). The areas under the curve (AUCs) for miR-134 and miR-1233 were, respectively, 0.931 (95% CI 0.863– 0.999) (P< 0.05) and 0.884 (95% CI 0.79– 0.978) (P< 0.05) and were higher compared with the AUC for D-dimer of 0.628 (95% CI 0.447– 0.809), the AUC for age-adjusted D-dimer of 0.705 (95% CI 0.525– 0.885) and the AUC for Wells score of 0.577 (95% CI 0.389– 0.765).Conclusion: Our study indicated that serum miR-1233 and miR-134 have high clinical value in the early diagnosis of AECOPD patients combined with APE, or could be used as potential biomarkers for clinical identification of AECOPD with or without APE complication.Keywords: acute exacerbation of chronic obstructive pulmonary disease, acute pulmonary embolism, D-dimer, microRNA, biomarker
