The invention provides methods of assessing unbound PCSK9 or effective PCSK9 activity in a subject based on the novel insights of the inventors that high levels of PCSK9 are bound to HDL in vivo and that this HDL can activate PCSK9 function. Specifically depleting HDL from a sample from a subject allows improved assessment of the level of unbound PCSK9. The invention provides such analytical methods, plus also associated methods of treatment and related kits.

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.

Disclosed is a method comprising acquiring a value relating to VEGF-A of a subject, wherein the value is a measured value of total VEGF-A in a blood sample, or a value obtained by dividing a measured value of VEGF-A.sub.165b in the blood sample by a measured value of total VEGF-A in the blood sample (VEGF-A.sub.165b/total VEGF-A), and the value suggests prognosis of myocardial infarction of the subject or severity of coronary artery disease of the subject.

This invention pertains to methods and compositions for the diagnosis and treatment of cardiovascular conditions. More specifically, the invention relates to isolated molecules that can be used to diagnose and/or treat cardiovascular conditions including cardiac hypertrophy, myocardial infarction, stroke, arteriosclerosis, and heart failure.

The present disclosure is directed to materials and methods for treating endothelial dysfunction in a subject in need thereof. Methods of determining efficacy of treatment are also provided.

The present invention inter alia provides a method, and use thereof, of predicting severe CVD complications such as AMI or CVD death by detecting the lipid concentrations or lipid ratios of a biological sample and comparing it to a control and has identified specific lipid markers that are more specific and sensitive in predicting these CVD complications than currently utilized clinical markers. Also provided is an antibodies towards said lipids, and the use thereof for predicting, diagnosing, preventing and/or treating CVD complications. The invention additionally relates to kits comprising lipids and/or an antibody thereto, for use in the prediction and/or diagnosis of CVD complications.

Antibodies and antigen-binding fragments of antibodies that bind to human fractional C-Reactive Protein (fracCRP), kits containing these antibodies and antibody fragments, and assays using these antibodies and antibody fragments.

The invention relates to a method of diagnosis or prognosis of an obliterative arteriopathy in a subject, comprising determining the expression level of adenosine A.sub.2A receptors expressed at the cell surface of peripheral blood mononuclear cells obtained from said subject. The invention also relates to an agonist-like monoclonal antibody directed to the human adenosine A.sub.2A receptor, useful for carrying out this method.

The present invention relates to endothelial cell biomarkers and diagnostic and prognostic methods for vascular diseases, including cardiovascular and cerebrovascular diseases. The invention also provides compositions for detecting endothelial cell biomarkers (e.g., endothelial cell-derived exosome biomarkers) as well as compositions and methods useful for treating vascular diseases (e.g., atherosclerotic cerebrovascular disease).

The invention provides decision tree based systems and methods for estimating the risk of acute coronary syndrome (ACS) in subjects suspect of having ACS. In particular, systems and methods are provided that employ additive decision tree based algorithms to process a subject's initial cardiac troponin I or T (cTnI or cTnT) concentration, a subject's cTnI or cTnT rate of change, and at least one of the following: the subject's age, the subject's gender, the subject's ECG value, the subject's hematology parameter value, to generate an estimate risk of ACS. Such risk stratification allows, for example, patients to be ruled in or rule out with regard to needing urgent treatment.
