Abstract:
Objectives:To investigate the expression and clinical implication of long non-coding RNA(lncRNA)metastasis associated lung adenocarcinoma transcript 1(MALAT1)in peripheral blood of patients with acute coronary syndrome(ACS). Methods:A total of 159 patients diagnosed with ACS who were admitted to the heart center of the First Affiliated Hospital of Xinjiang Medical University from January 2015 to December 2018 were selected as the ACS group,and 148 participants without coronary heart disease confirmed by physical examination and enhanced coronary CT examination in the physical examination center of our hospital during the same period were selected as the control group.Peripheral blood mononuclear cells of patients in two groups were extracted,and the expression level of MALAT1 was detected by real-time fluorescence quantitative polymerase chain reaction(qRT-PCR),and the correlation between the expression level of MALAT1 and ACS and the diagnostic and prognostic value of MALATI expression level for ACS were analyzed. Results:The expression level of MALAT1 in peripheral blood was significantly higher in the ACS group than in the control group(P<0.05).Multivariate logistic regression analysis showed that the expression level of MALAT1 in peripheral blood was independently correlated with ACS(OR=1.193,95%CI:1.037-1.372,P=0.014).ROC curve showed that the expression level of MALAT1 in peripheral blood was of certain diagnostic value for ACS(AUC=0.664,95%CI:0.600-0.720).Kaplan-Meier survival analysis showed that ACS patients with high expression level of MALAT1 in peripheral blood(≥0.816)had higher cumulative incidence of major adverse cardiovascular events than those with low expression level of MALAT1 in peripheral blood(<0.816)during(558±223)days follow-up(39.05%vs.30.61%,P<0.05). Conclusions:The expression level of MALAT1 in peripheral blood of patients with ACS is significantly increased,and the expression level of MALAT1 in peripheral blood has potential clinical value for the diagnosis and prognosis of patients with ACS.
