Aim: To investigate correlations of long noncoding RNA metastasis-associated lung adenocarcinoma transcript 1 (lnc-MALAT1) and its target microRNAs with clinical features and restenosis risk in coronary heart disease (CHD) patients post drug-eluting stent-percutaneous coronary intervention(DES-PCI). Materials & methods: A total of274 CHD patients undergoing DES-PCI were enrolled, pre-operative plasma samples were obtained to detect lnc-MALAT1, miR-125b, miR-146a, miR-203 by RT-qPCR; 2-year restenosis was determined by quantitative coronary angiography. Results: Lnc-MALAT1 negatively correlated with miR-125b, miR-146a and miR-203. Furthermore, lnc-MALAT1, miR-125b, miR-146a and miR-203 correlated with diabetes mellitus, hyperuricemia, lesion properties, cholesterol, inflammation and cardiac function indexes. Additionally, lnc-MALAT1 was increased, while miR-125b and miR-146a were decreased in patients with 2-year restenosis than patients without 2-year restenosis; however, miR-203 did not differ. Conclusion: Lnc-MALAT1 and its target miRNAs might help manage restenosis risk in CHD patients post DES-PCI.
