H19 and coronary artery disorder: Figure 5(d) depicts the top 20 abnormally expressed circulating lncRNAs. To increase the reliability of the results, we overlapped the abnormally expressed lncRNAs in the GSE113079 and GSE69587 datasets. Consequently, 12 upregulated lncRNAs were obtained for CAD, including AC004485.3, AC004920.3, AJ006998.2, H19, RP11-247A12.1, RP11-288L9.4, RP11-344B5.2, RP11-452C8.1, RP11-565A3.1, RP5-1114G22.2, RP5-902P8.10, and XXbac-B33L19.4 (Figure 6(a)). Moreover, LOC338758 was downregulated in CAD blood samples (Figure 6(b)).
