A method for diagnosing acute coronary syndrome (ACS) in a subject, the method comprising measuring plasma macrophage migration inhibitory factor (MIF) concentration in a sample from the subject, and diagnosing ACS when the subject plasma MIF concentration is greater than a reference plasma MIF concentration, wherein the sample is taken less than 4 hours after symptom onset. The invention also relates to a method for prognosing ACS in a subject, the method comprising measuring plasma MIF concentration in a sample from the subject, diagnosing ACS when the subject plasma MIF concentration is greater than a reference plasma MIF concentration, and prognosing the magnitude of ACS from the subject plasma MIF concentration. Also provided is a method of treating ACS in a subject, a device, a kit, and a cardiac biomarker related to the methods of diagnosing and prognosing ACS.

The present invention inter alia provides a method, and use thereof, of predicting CV complications such as AMI, ACS, stroke, and CV death by determining the concentrations of at least one ceramide of Group A and at least one ceramide of Group B in a biological sample and comparing those concentrations to a control. Finding a decreased concentration of at least one Group A ceramide and an increased concentration of at least one Group B ceramide indicates that the subject has an increased risk of developing one or more CV complications. Also provided are a newly identified subset of ceramide molecules, labelled versions thereof, and kits and compositions comprising the same for use in predicting and/or diagnosing CV complications.

An application method of at least one of a THBS1 protein and a THBS3 protein as biomarkers for detecting acute myocardial infarction is provided, which belongs to the field of biomedical technology. The THBS1 protein and THBS3 protein in peripheral plasma are low expressed in patients with acute myocardial infarction through proteomic results, the proteomic results are verified by expanding the number of patients’ samples, and the two proteins can be used as molecular markers for the diagnosis of acute myocardial infarction. It has the advantages that: (1) peripheral blood samples are easy to obtain, saving time and labor; (2) the experiment is simple and easy to operate; (3) a new intervention target for diagnosis and treatment of acute myocardial infarction is found; (4) a new direction is provided for treating acute myocardial infarction and improving prognosis in the future; and (5) a new idea is provided for precision medicine.

The present invention relates to a polypeptide carrying a human BNP(1-32) epitope according to Formula (I): a.sub.1-R.sub.1-X.sub.1-FGRKMDR-X.sub.2-R.sub.2-a.sub.2 as well as ligands specific of the FGRKMDR epitope.

The technology described in this document can be embodied in a test strip for use in measuring a level of an ST2 cardiac biomarker in a whole blood sample. The test strip includes a base, and a plurality of conjugates, wherein each conjugate includes a reporter group bound to a first antibody that binds to ST2. A conjugate pad holds the plurality of conjugates that bind with ST2 to produce conjugate-ST2 complexes. The test strip also includes a plurality of second antibodies that bind to ST2, and a plurality of third antibodies that bind to the conjugate-ST2 complexes. The plurality of second antibodies are bound to a membrane in a test location, and the plurality of third antibodies are bound to the membrane in a control location. A plasma separation pad passes blood plasma from a whole blood sample to the conjugate pad while inhibiting other components.

The present invention provides compositions and methods based on genetic polymorphisms that are associated with coronary heart disease (particularly myocardial infarction), aneurysm/dissection, and/or response to drug treatment, particularly statin treatment. For example, the present invention relates to nucleic acid molecules containing the polymorphisms, variant proteins encoded by these nucleic acid molecules, reagents for detecting the polymorphic nucleic acid molecules and variant proteins, and methods of using the nucleic acid molecules and proteins as well as methods of using reagents for their detection.

The invention is directed to a method to test a subject having, or at risk for having, atherosclerosis, the method comprising obtaining peripheral blood cells, particularly mononuclear cells, from the subject and assaying the cells for gene expression of one or more components of the STING (stimulator of interferon genes) pathway relative to an appropriate baseline control. The invention is also directed to a composition comprising a peripheral blood cell that is co-stained for a marker that is specific for the peripheral blood cell and for a marker that is specific for gene expression of a component of the STING pathway, the peripheral blood cell being derived from a subject having or at risk for having atherosclerosis. Peripheral blood cells include B lymphocytes, T lymphocytes, monocytes and natural killer cells. Specific subsets of lymphocytes include CD4.sup.+ and CD8.sup.+ T lymphocytes.

Some embodiments of the methods and compositions provided herein relate to the detection of biomarkers for Kawasaki disease (KD), the diagnosis of KD in a subject, and/or the amelioration or treatment of KD in a subject. In some embodiments, a biomarker can include a long intergenic non-coding RNA (lincRNA). In some embodiments, the biomarker can be present in an exosome-enriched serum sample from a subject.

The present invention relates to a method for prediction of response to cardiovascular regeneration comprising the use of biomarkers. Further, the present invention relates to a combination of the biomarkers for use in a method for prediction of response to cardiovascular regeneration, a computer device to perform a method according to the present invention and a device adapted for carrying out the inventive method.

The present invention provides a method for the early diagnosis, prognosis and differentiation of ischemic cardiac events in myocardial ischemia by a Nourin gene-based RNA molecular network of biomarkers to: (a) diagnose unstable angina and AMI (STEMI and NSTEMI) patients, and differentiate between unstable angina and AMI; (b) diagnose ACS patients and differentiate them from symptomatic non-cardiac patients and healthy subjects; (c) diagnose angina in suspected patients with history of chest pain and differentiate angina patients from symptomatic non-angina and healthy subjects; and (d) diagnose “new-onset” heart failure and provide a prognostic value and risk prediction of progression and deterioration, as well as monitoring patients' response to treatments. Downregulation of Nourin-related lncR-CTB9H12.4 in ischemic heart disease patients compared to symptomatic non-cardiac and healthy subjects, is significantly associated with upregulation of hsa-miR-137 and hsa-miR-106b, and overexpression of mRNA-FTHL-17 and mRNA-ANAPC11, respectively, that results in upregulation of Nourin gene and protein network.
