A study in humans with coronary artery disease identified the miR-6720-3p as a biomarker for recurrent myocardial infarction risk, where it was downregulated in whole blood of patients with recurrent MI compared to those without, remaining significant after false discovery rate correction (FDR ≤0.1) in a replication cohort, though it was not significantly different in plasma samples [Onuoha et al. DOI:10.1111/cts.13307].
