NT-proBNP can be determined in a biological sample using at least one antibody which recognizes an epitope of NT-proBNP in both a glycosylated and non-glycosylated form of NT-proBNP. Said antibody is preferably an isolated polyclonal antibody or a mixture of monoclonal antibodies coated onto a particle, preferably coated onto said particle in a coating ratio of 6-60%, forming a layer or multiple layers of antibodies on said particle. The assay, realized in the form of a nephelometric or turbidimetric assay, can be applied to a wide range of automated clinical analyzers.

The present invention relates to a method for differentiating between heart failure with preserved ejection fraction (HFpEF) and heart failure with reduced ejection fraction (HFrEF) in a subject suffering from heart failure, said method comprising the steps of determining the amounts of IGFBP7 (Insulin-like growth factor-binding protein 7), of a BNP-type peptide, and optionally of CRP (C-reactive protein) in a sample from the subject, calculating (i) a ratio of the amount of IGFBP7 and the amount of the BNP-peptide or (ii) a ratio of the sum of the amounts of IGFBP7 and CRP and the amount of the BNP-type peptide, comparing the ratio calculated with a reference ratio, and differentiating between heart failure with preserved ejection fraction (HFpEF) and heart failure with reduced ejection fraction (HFrEF). The present invention further concerns a method for the diagnosis of HFpEF.

The present invention relates to a method of identifying a subject being susceptible to a cardiac intervention based on the determination of GDF-15 in a sample of a subject in need of a cardiac intervention. Moreover, the present invention pertains to a method for predicting the risk of mortality or a further acute cardiovascular event for a subject suffering from a cardiovascular complication based on the determination of GDF-15 and a natriuretic peptide and/or a cardiac troponin in a sample the said subject. Also encompassed by the present invention are devices and kits for carrying out the aforementioned methods.

The present disclosure relates to an antibody that specifically binds a mutated NT-proBNP having i) a mutation substituting arginine at position 46 with histidine or ii) a mutation substituting glutamic acid at position 43 with aspartic acid. Moreover, the present disclosure relates to a mutated NT-proBNP or fragment thereof. Further, envisaged by the present disclosure are kits containing the antibody of the present disclosure, or the mutated NT-proBNP of the present disclosure. The present disclosure also concerns a method for diagnosing heart failure.

The invention pertains to a method for the prognosis and/or risk assessment and/or diagnosis of a major adverse cardio- or cerebrovascular event (MACCE) in a patient who underwent gastrointestinal surgery, the method comprising the steps of: i) providing a sample of a bodily fluid from said patient, ii) determining in said sample the level of a biomarker selected from the group consisting of copeptin, troponin and brain natriuretic peptide (BNP), iii) determining at least one additional parameter of said patient, iv) combining the biomarker level determined in step ii) and the additional parameter determined in step iii) into a combined assessment, and v) correlating the combined assessment to said at least one of prognosis, risk assessment and diagnosis of a MACCE in said patient. The invention further pertains to a kit for carrying out the method, a computer and a computer program product comprising computer-executable code being configured to carry out steps iv) and/or v) of the method of the invention.

Methods, apparatuses and systems are described that are capable of simultaneously determining the presence, identities or levels of multiple analytes present in a single sample, by carrying out steps including denaturation, normalization, extraction, mixed-mode liquid chromatography and mass spectrometry, whereby the presence, identities or levels of analytes in the single sample are determined.

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.

This document provides methods and materials related to using natriuretic peptides (NPs) as markers for acute kidney injury (AKI), and methods and materials for using NPs to treat patients identified as having, or being likely to have, AKI.

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 disclosure relates to a novel isolated binding protein including a N-terminal pro-brain natriuretic peptide (NT-proBNP) antigen binding domain, and the preparation method therefor. The antigen-binding domain includes at least one complementarity determining region selected from the amino acid sequences as defined in the present disclosure: or; has at least 80% sequence identity with the complementarity determining region of the following amino acid sequence and has an affinity of KD≤2.26×10.sup.−8 to NT-proBNP. The binding protein may be used in the detection field of NT-proBNP protein.
