The present disclosure relates to a method for diagnosing preeclampsia or a preeclampsia-related condition in a pregnant subject. The method is based on the measurement of the amount of the biomarker IGFBP-7 (Insulin-like Growth Factor Binding Protein 7) in a sample from the subject and on the comparison of the measured amount to a reference. Also disclosed are methods for assessing the severity of preeclampsia or a preeclampsia-related condition and methods for monitoring a preeclampsia or a preeclampsia-related condition in a pregnant subject. The present disclosure further relates to the use of the biomarker IGFBP-7 or of an agent that specifically binds to IGFBP-7 in a sample from a pregnant subject for diagnosing, for monitoring or for assessing the severity of preeclampsia or a preeclampsia-related condition. Finally, the present disclosure relates to a device or kit adapted to carry out the method of the present invention.

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.

The present disclosure is directed to a method of identifying a patient having heart failure as likely to respond to a therapy with a statin. The method is based on measuring the level of at least one marker selected from GDF-15 (Growth Differentiation Factor 15), Urea, SHBG (Sex Hormone-Binding Globulin), Uric acid, PLGF (Placental Growth Factor), IL-6 (Interleukin-6), Transferrin, a cardiac Troponin, sFlt-1 (Soluble fms-like tyrosine kinase-1), Prealbumin, Ferritin, Osteopontin, sST2 (soluble ST2), and hsCRP (high sensitivity C-reactive protein) in a sample from a patient. Further envisaged is a method of predicting the risk of a patient to suffer from death or hospitalization, wherein the patient has heart failure and undergoes a therapy with a statin. The method is also based on the measurement of the level of at least one of the aforementioned markers.

Marker for statin treatment stratification in heart failure

The present invention relates to a method for assessing whether a subject shall be subjected to an imaging based diagnostic assessment. The method is based on the determination of the amount(s) of a cardiac Troponin and/or Fibroblast Growth Factor 23 (FGF-23) in a sample from the subject, and on the comparison of the, thus, determined amount(s) with a reference amount (reference amounts). The present invention also relates to a system for performing an assessment whether a subject shall be subjected to an imaging based diagnostic assessment and to reagents and kits used in performing the methods disclosed herein. Moreover, the present invention is directed to a method for predicting the risk of mortality and/or of a cardiovascular event. Also encompassed is a method for diagnosing an early stage of LVH in a subject having a preserved left ventricular ejection.
