    ObjectiveThis study aimed to investigate the expression level of lncRNA myocardial infarction associated transcript (MIAT) in serum of pregnant women with hypertensive disorders in pregnancy (HDP) and its clinical significance.MethodsA total of 135 pregnant women with HDP were selected, including 69 pregnant women with gestational hypertension (GH) and 66 pregnant women with preeclampsia (PE). Sixty-eight normal pregnant women were selected as healthy control group (HC). The expression level of serum MIAT of all subjects was detected by quantitative real-time polymerase chain reaction (qRT-PCR), and the diagnostic value of MIAT for GH was evaluated by constructing receiver operating characteristic (ROC) curve. Pearson correlation coefficient was used to analyze the correlation between MIAT and patients' clinical indicators. Logistics regression analysis evaluated the influencing factors of GH development into PE.ResultsThe level of MIAT in GH group was significantly higher than that in HC group, while MIAT level in PE group was more significantly upregulated than that in GH group and HC group. ROC curve showed that MIAT had the ability to distinguish between GH patients and healthy controls. Pearson correlation coefficient suggested that HOTAIR expression was positively correlated with systolic blood pressure (SBP) and diastolic blood pressure (DPB). Logistic regression analysis showed that MIAT was an independent influencing factor for the development of GH to PE.ConclusionThe expression of MIAT in serum of HDP patients was increased and positively correlated with the severity of the disease. The abnormal expression of MIAT has certain diagnostic value for GH.© 2021. The Author(s), under exclusive licence to Royal Academy of Medicine in Ireland.
