Background Little is known about the underlying factors contributing to unfavourable clinical outcomes in patients with diabetes mellitus (DM) complicated by new-onset acute myocardial infarction (AMI). The aim of this study was to investigate the impact of DM on the pathophysiologic features and prognosis of patients with new-onset AMI following successful revascularization by utilizing cardiac magnetic resonance (CMR).Methods Consecutive patients diagnosed with new-onset AMI between June 2022 and January 2024 were included. All patients underwent culprit vessel revascularization upon admission and CMR imaging 3-7 days later. The primary clinical endpoint of this study was the occurrence of major adverse cardiac and cerebrovascular events (MACCEs), for which the average follow-up was 10 months.Results A total of 72 patients were divided into a DM group (n = 23) and a non-DM group (n = 49). Multivariate logistic regression analysis revealed that DM was an independent risk factor for the occurrence of microvascular obstruction. Multivariate linear regression analysis found that DM was the influencing factor of global radial strain (B = −4.107, t = −2.328, p = 0.023), while fasting blood glucose influenced infarct segment myocardial radial strain (B = −0.622, t = −2.032, p = 0.046). DM independently contributed to the risk of MACCEs following successful revascularization in patients with AMI (p

Introduction: Acute cerebral ischemic stroke (AIS) dramatically influences patients' quality of life. lncRNA NORAD (NORAD) has been studied in cerebrovascular diseases, which are potential risk factors for AIS. The specific significance of NORAD is unclear. This study aimed to assess the role of NORAD in AIS, and to provide therapeutic value for its' treatment. Material and methods: A total of 103 AIS patients and 95 healthy individuals (control) were enrolled into this study. Expression level of NORAD in the plasma of all participants was analyzed by PCR. Diagnostic potential of NORAD in AIS was evaluated by ROC analysis, while Kaplan-Meier and Cox regression analyses were conducted to assess its' prognostic value in AIS. Results: A significantly increased level of NORAD was observed in AIS patients compared with healthy individuals. The upregulation of NORAD could dramatically discriminate AIS patients from healthy individuals with high sensitivity (81.60%) and specificity (88.40%). NORAD was positively correlated with patients' high-sensitivity C-reactive protein (hs CRP, r = 0.796), matrix metalloproteinase-9 (MMP9, r = 0.757), and NIHSS scores (r = 0.840), and negatively related to pc-ASPECTS scores (r = -0.607). Moreover, NORAD upregulation was associated with patients' unfavorable prognosis and served as an independent prognostic biomarker, together with NIHSS and pc-ASPECTS scores of AIS patients. Conclusions: NORAD was upregulated in AIS, which can discriminate AIS patients, and was closely correlated with severe development and poor prognosis of patients. [ABSTRACT FROM AUTHOR]
