Disclosed are compositions and methods for determining aberrant cardiac function or a predisposition to aberrant cardiac function, said method comprising detecting a fragment of βII spectrin associated with aberrant cardiac function or a predisposition to aberrant cardiac function in a sample derived from a subject, wherein the detection is indicative of aberrant cardiac function in the subject.

Embodiments of the invention are directed to methods, systems and computer programs that provide improved risk stratification for people having elevated large HDL-P using at least one defined HDL risk interaction parameter.

The current methods and compositions relate to treatment of atrial fibrillation with bucindolol in patients, including patients with heart failure, after being determined to be homozygous Arg389 in the β.sub.1 adrenergic receptor gene.

Subject matter of the present invention is a method for (a) diagnosing or predicting the risk of life-threatening deterioration or an adverse event or (b) diagnosing or prognosing the severity or (c) predicting or monitoring the success of a therapy or intervention or (d) therapy guidance or therapy stratification or (e) patient management in a patient infected with a coronavirus, the method comprising: determining the level of dipeptidyl peptidase 3 (DPP3) in a sample of bodily fluid of said patient, comparing said level of determined DPP3 to a pre-determined threshold, and correlating said level of determined DPP3 with the risk of life-threatening deterioration or an adverse event, or correlating said level of determined DPP3 with the severity, or correlating said level of determined DPP3 with the success of a therapy or intervention, or correlating said level of DPP3 with a certain therapy or intervention, or correlating said level of DPP3 with the management of said patient.

Subject matter of the present invention is an inhibitor of the activity of DPP3 for use in therapy or intervention in a patient infected with a coronavirus.

A heart failure marker that is simple, and preferably usable by non-invasive test. A method for measuring heart failure risk, comprising: (A) measuring an angiotensinogen amount value of urine collected from a subject.

The present invention relates to a method for assessing atrial fibrillation in a subject, said method comprising the steps of determining the amount of BMP10 in a sample from the subject, and comparing the amount of BMP10 to a reference amount, whereby atrial fibrillation is to be assessed. Moreover, the present invention relates to a method for diagnosing heart failure based on the determination of BMP 10 in a sample from a subject. Further, the present invention relates to a method for predicting the risk of a subject of hospitalization due to heart failure based on the determination of a BMP10-type peptide in a sample from a subject. The present invention further pertains to antibodies which bind to one or more BMP10-type peptides such as NT-proBMP10.

The disclosure provides methods for detecting and diagnosing diseases and conditions associated with defects in cardiolipin remodeling. In some embodiments, the present technology relates to methods for detecting the presence or amount of cardiolipin isoforms and/or the presence or amount of enzymes involved in cardiolipin remodeling.

The disclosure is directed to methods for preventing or treating cardiovascular disease and kidney dysfunction in certain patient populations which involve determining the level of soluble urokinase plasminogen activator receptor (suPAR) protein in a sample obtained from a subject, and performing various therapeutic interventions based on the suPAR level in the sample.

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 provides an application of neuregulin protein in the preparation of drugs for preventing, treating or delaying human heart failure, and a use method of the drugs for preventing, treating or delaying human heart failure. The method comprises: testing a patient first before treatment, the testing comprises detecting the plasma level of NT-proBNP or BNP; and then providing appropriate treatment on the basis of the test result. When the test result is within an optimal treatment range, the patient is suitable for the treatment of heart failure by administering an effective dose of neuregulin.
