Problems solved by technology

Cardiovascular diseases can remain asymptomatic for long periods of time.
However, they may have severe consequences once an acute cardiovascular event, such as myocardial infarction (MI) or acute decompensated heart failure (ADHF), occurs.
The conventional diagnostic techniques, specifically for emergency situations, usually do not allow for a reliable diagnosis and/or risk assessment covering these various pathological states.
Further drawbacks are the lack of sufficient personnel for carrying out sophisticated diagnostic techniques and assays and the varying occupancy in emergency rooms.

example 1

[0198]We herewith demonstrate that use of sCD14-ST improves detection of subjects at elevated risk for developing a cardiovascular disease or condition, diagnosis of acute coronary syndrome (ACS), acute myocardial infarction (MI), and acute heart failure (AHF) as well as decision making in the emergency room and the overall management of patients presenting to emergency departments by evaluating the diagnostic and prognostic power of sCD14-ST and prospectively examining the clinical impact of sCD14-ST concentration guided decision making regarding discharge, admission to hospital, intensive care treatment, prevention, and therapeutic measures in cardiovascular diseases or conditions. sCD14-ST was measured in samples obtained from a control group of healthy individuals and patients with different cardiac diseases:[0199]Chronic heart failure (HF), n=40[0200]Angina pectoris (AP) and unstable angina pectoris (UAP), n=17[0201]Non-ST-elevation myocardial infarction (NSTEMI), n=29[0202]Acu...

Reference Interval

[0206]A healthy control group (reference population) was used including 60 men and 59 women (age ranging from 21 to 69 years, median age 42 years) who fulfilled the following criteria: chronic diseases and intake of medications were excluded by questionnaire; physical examination, assessment of blood pressure, ECG registrations, and oral glucose tolerance tests yielded no pathological findings; plasma concentrations of N-terminal pro-B-type natriuretic peptide were ≦125 pg / ml; concentrations of TSH, creatinine and HbA1c were normal; cardiovascular diseases were excluded by cardiac magnetic resonance imaging including a dobutamine stress test.

[0207]sCD14-ST concentrations were determined in EDTA plasma samples of the control group using the PATHFAST assay. The 99th percentile upper reference limit (URL) according to the Clinical Laboratory Standard Institute (CLSI) Guideline C28-A3 was 258 (90% CI: 237-276) pg / ml. The results are displayed in Tab. 1.

sCD14-ST Levels in Patients with Chronic Heart Failure (CHF)

[0208]sCD14-ST concentrations were measured in EDTA plasma samples obtained from 40 patients with chronic heart failure (New York Health Association (NYHA) classification I-III).

Abstract

The present invention relates to a method for diagnosis of a cardiovascular disease or condition or atherosclerosis and for a method for evaluating the risk of a subject of developing the same. Methods are further provided for evaluating a subject's risk of mortality, for evaluating whether a subject will benefit from a certain treatment or whether a subject needs to be hospitalized or whether a subject may be discharged. The present invention provides sCD14 or a fragment or derivative thereof (including in particular sCD14-ST) as a novel marker for cardiovascular risk in general, more specifically as a marker for cardiovascular disease or condition, or atherosclerosis.

Description

FIELD OF THE INVENTION[0001]The present invention relates to the field of means for assessing a diagnosis or a prognosis with respect to cardiovascular diseases or conditions or atherosclerosis, and to methods for evaluating the cardiovascular or atherosclerotic risk of a subject.[0002]More specifically, the present invention relates to novel methods for diagnosing a cardiovascular disease or condition or atherosclerosis. sCD14, sCD14-ST, or a fragment or derivative of sCD14 other than sCD14-ST is provided as a novel marker for diagnosis of cardiovascular diseases or conditions or atherosclerosis. The present invention further comprises a method for the evaluation of a subject's risk of developing a future cardiovascular disease or condition or atherosclerosis. Furthermore, methods are provided for the diagnosis of an acute cardiac event in subjects showing signs of a cardiovascular disease or condition or atherosclerosis. Preferably, the method according to the present invention pe...
