Downregulated Circulating Long Non-coding RNA GAS6-AS1 Screens and Predicts Acute Myocardial Infarction.

BACKGROUND

Acute myocardial infarction seriously threatens human health and life quality, which needs novel biomarkers to improve its early detection and development prediction. This study aimed to assess the potential of long non-coding RNA GAS6-AS1 in discriminating acute myocardial infarction patients and predicting patients' outcomes.

METHODS

The circulating expression of GAS6-AS1 in 83 acute myocardial infarction patients and 62 healthy individuals was evaluated using polymerase chain reaction. The value of GAS6-AS1 in the distinguishing acute myocardial infarction patients was evaluated with receiver operating characteristic analysis, and its prognosis predictive potential was assessed by Kaplan-Meier and Cox analysis. Additionally, the correlation of GAS6-AS1 with patients' critical features was evaluated by Spearman's correlation analysis.

RESULTS

Significant downregulation of GAS6-AS1 was observed in the plasma of acute myocardial infarction patients relative to healthy individuals. Reduced GAS6-AS1 could discriminate acute myocardial infarction patients from healthy controls and indicate patients' unoptimistic prognosis. Moreover, GAS6-AS1 was found to be negatively cor-related with the levels of creatine kinase, creatine kinasemyocardial bland, lactic dehy-drogenase, hydroxybutyrate dehydrogenase, troponin T, and positively correlated with the ejection fraction of acute myocardial infarction patients.

CONCLUSION

Changes in circulating GAS6-AS1 in acute myocardial infarction served as a potential diagnostic and prognostic biomarker of acute myocardial infarction.
