Their peripheral blood mononuclear cells were obtained to measure lnc\u2010MALAT1 by RT\u2013qPCR. Serum cytokines in AMI patients were detected by ELISA. In addition, AMI patients were followed up for major adverse cardiovascular event (MACE) risk evaluation.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Lnc\u2010MALAT1 was higher in AMI patients than in controls (median: 2.245 vs. 0.996, <jats:italic>p<\/jats:italic>\u00a0=\u00a00.004), and it also presented a good capacity for differentiating AMI patients from controls with an area under the curve of 0.823. Lnc\u2010MALAT1 was positively related to C\u2010reactive protein (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.005), low\u2010density lipoprotein cholesterol (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.022), cardiac troponin I (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.021), and infarct size (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.007), but not other biochemical indexes in AMI patients. Meanwhile, lnc\u2010MALAT1 was positively associated with tumor necrosis factor\u2010alpha (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.001), interleukin (IL)\u20106 (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.031), IL\u201017A (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.042), vascular cell adhesion molecule\u20101 (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.004), and intercellular adhesion molecule\u20101 (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.021) among AMI patients. Importantly, after categorization, lnc\u2010MALAT1 high (vs. low) was related to an elevated MACE accumulation rate (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.035); furthermore, a higher
