MiRNA libraries were prepared from RNA samples of 16 patent and 18 STEMI patients, using the QIAseq miRNA Library Kit (Qiagen).  Library concentrations were measured with Qubit dsDNA HS Assay Kit (Molecular Probes Life Technology) and the quality was assessed by Bioanalyzer and TapeStation systems (Agilent). All miRNA libraries were sequenced using Nextseq 550 (Illumina) with a read length of 75 bp.
