Correlation analysis in heart failure patients showed a significant favorable correlation between lnc-MEG3 and lnc-Chaer and a good positive correlation between mir361-5p and lnc-MEG3; however, a negative connection was seen between serum mir675 and mir361-5p, lnc-MEG3, and lnc-Chaer (Table 9). Here, MEG3 is linked to heart failure.
