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.

This invention provides gene expression profiles useful for diagnosing atrial fibrillation in ischemic stroke and for distinguishing atrial fibrillation in ischemic stroke from arterial (large vessel) stroke or embolic stroke of undetermined source (ESUS). In another aspect, the present invention is the provision of an improved method for prognosis of an outcome or assessing the risk of a patient having suffered a stroke or a transient ischemic attack, comprising determining the level of expression of at least one biomarker in a sample of the patient.

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 present invention relates to a specific set of circulating biomarkers and related methods and kits for the diagnosis of Brugada Syndrome in a human being.

The present invention relates to a method for diagnosing a recent paroxysmal atrial fibrillation. The method is based on the determination of the at least one marker selected from the group consisting of a cardiac Troponin, NT-proBNP (N-terminal prohormone of brain natriuretic peptide), hsCRP, IL-6 (Interleukin-6) and IGFBP7 (Insulin like growth factor binding protein 7) in a sample from the subject, and on the comparison of the, thus, determined amount(s) with a reference amount (reference amounts). Further, the present invention relates to a method for identifying a subject being treatable with anticoagulation therapy. Further envisaged are systems, reagents and kits used in performing the methods disclosed herein.

A method for predicting the risk of recurrence of Atrial Fibrillation in a subject based on measuring the amount of the biomarker Angiopoietin-2 (Ang-2) and optionally of at least one further biomarker in a sample from the subject is described. Also described is a method of diagnosing Atrial Fibrillation in a subject suspected to suffer from Atrial Fibrillation based on measuring the amount of the biomarker Angiopoietin-2 (Ang-2) and optionally of at least one further biomarker in a sample from the subject. Also described are devices adapted to carry out the method of the present disclosure.

A method of providing information for predicting a risk of a recurrence after treatment of a patient with paroxysmal atrial fibrillation (AF) is provided. The method includes measuring a concentration of tissue inhibitor of metalloproteinase (TIMP)-1 from a sample isolated from a patient, and detecting a presence of a genetic variant at rs10033464 GG on chromosome 4q25 from nucleic acid separated from the sample.

The present invention relates to a method for aiding in the prediction of stroke and/or dementia in a subject, said method comprising a) determining the amount of the biomarker RET (Rearranged during transfection) in a sample from the subject, b) comparing the amount determined in step a) to a reference, and c) aiding in the prediction of stroke and/or dementia. The present invention further relates to a method for aiding in the assessment of the extent of white matter lesions in a subject, a method for aiding in the assessment whether a subject has experienced one or more silent strokes and to a method for aiding in the diagnosis of atrial fibrillation in a subject. Further encompassed by the present invention are the corresponding uses.

The present invention relates to a method of diagnosing whether a subject with no known history of atrial fibrillation is suffering from atrial fibrillation, or not, said method comprising the steps of a) determining the amount of a BNP-type peptide in a sample of said subject; b) comparing the amount the BNP-type peptide to a reference, and c) assessing intermittent ECG recordings obtained from said subject over a period of at least one week by using a handheld ECG device.

The present invention relates to a method of determining the risk of drug induced arrhythmia using stem cell derived cardiomyocytes in a high-throughput impedance or multi-electrode array assay.
