The invention provides methods of detecting a natriuretic protein, a troponin, and galectin-3 in samples from subjects in order to determine risk of developing new onset heart failure with preserved ejection fraction (HFpEF).

The present invention provides methods for treating chronic heart failure patients using the medication comprising neuregulin. The methods comprise first performing a companion diagnostic test of each patient before treatment; and then providing a suitable treatment to the patient according to the results of the companion diagnostic test. When the result of the test is within a favorite treatment zone, the patient is suitable for heart failure treatment by administering an effective amount of neuregulin.

The present invention provides a method for predicting whether a human patient 65 years of age or older is at increased risk for developing heart failure, comprising obtaining the results of an assay that measures levels of NT-proBNP and/or cardiac troponin T in a specimen from the patient wherein an increased NT-proBNP and/or cardiac troponin T level compared to levels in a control indicate an increased risk for developing heart failure.

Provided is a cardiotoxicity assessment method which comprises: seeding cardiomyocytes in a culture container together with a culture medium; adding a drug to the culture medium in the culture container to bring the drug into contact with the cardiomyocytes; and measuring a heart disease biomarker secreted from the cardiomyocytes to assess cardiotoxicity of the drug, wherein at least a culture surface of the culture container is composed of an alicyclic structure-containing polymer, and the culture surface has a surface free energy of 30 to 37 mN/m.

The present invention relates to a method for predicting the risk of a subject of rapidly progressing to chronic heart failure and/or of hospitalization due to chronic heart failure and/or death. The method is based on the determination of at least one biomarker selected from the group consisting of a BNP-type peptide, IGFBP7 (IGF binding protein 7), a cardiac Troponin, soluble ST2 (sST2), FGF-23 (Fibroblast Growth Factor 23), and Growth Differentiation Factor 15 (GDF-15), in a sample of a subject. The method may further encompass the assessment of the presence or absence of (i) abnormal midwall fractional shortening or (ii) left ventricular hypertrophy. Further envisaged by the present invention are devices adapted to carry out the present invention.

The present disclosure relates to assays for detecting and/or quantifying the amount of human NT-pro B-type natriuretic peptide, human pro B-type natriuretic peptide and human B-type natriuretic peptide in a test sample.

Subject of the present invention are biomarkers and methods for the identification of risk for subsequent cardiovascular event (e.g. coronary heart disease death, non-fatal myocardial infarction, ischemic stroke, hospitalizations for unstable angina pectotis, cardiac arrest) in patients that have experienced an acute coronary syndrome, comprising the detecting the level of NT-proBNP, homocysteine and CRP.

Methods, techniques, systems and compositions to reduce or prevent the aggregation and/or epitope masking of control/calibration peptides. The methods described herein may be particularly helpful for calibration and quantifying target proteins from immunoassays such as solid-phase enzyme immunoassays (EIAs).
