About this study
Official title: The Importance of Vascular Endothelial Growth Factor (VEGF), Hepatocyte Growth Factor (HGF) and Platelet Derived Growth Factor (PDGF) as a New Indicators of Myocardial Ischemic Injury in Comparison With Commonly Used Biomarkers.
The main aim of the study is a comparison of serum and plasma concentration of VEGF (Vascular Endothelial Growth Factor), HGF (Hepatocyte Growth Factor) and PDGF (Platelet Derived Growth Factor) with markers of myocardial injury as troponin I, hsCRP, CK-MB and NT-proBNP assessed in patients with first episode of acute coronary syndrome (ACS) in their lives and the estimation of assumed value of VEGF, HGF and PDGF in prognosis of cardiovascular complications at 3 months follow up especially with respect to myocardial infarction (MI), exacerbation of angina, reintervention (PTCA,CABG), symptoms of heart failure, stroke, rehospitalization due to cardiovascular reasons and death. The dynamics of changes in serum and plasma concentration of growth factors in comparison with values of myocardial injury markers will be checked. For the realization of the purpose of the study biochemical measurements will be performed twice i.e. just after admission to hospital and 24h later. Area of a myocardial injury will be estimated by echocardiography examination.
Read the detailed description
In the recent years several biomarkers have been investigated to be used for diagnostic and risk stratification in patients with symptoms of acute coronary syndrome. Troponins are preferred markers for myocardial injury due to its high specificity and sensitivity what makes them superior than traditional cardiac enzymes as CK or CK-MB. Elevated level of NT-proBNP is a marker of heart failure strongly associated with increased mortality rate. This study is invented for searching new sensitive indicators of myocardial injury and predictors of bad outcome in patients with symptoms of ACS especially useful in difficult diagnostic and therapeutic situations.
The study is performed in patients with first episode of ACS in their life who are eligible for coronary angiography and eventually for PCI. All subjects who agree to participate in the study are informed of its nature and purpose. Patients, only due to the symptoms and according to ESC guidelines are referred for coronary angiography, primary PCI, surgery revascularisation and pharmacological treatment. Inclusion into the study does not influence on the type of the treatment. The measurements of VEGF, HGF, PDGF, troponin I, hsCRP, CK-MB and NT-proBNP are assessed twice i.e. as soon as possible after admission to hospital and 24h after the first measurements. For estimation of changes in concentration of growth factors in time in some patients the multiple assessments will be performed (9 measurements during first 24h and 1 before discharge from hospital). In healthy volunteers (10 to 20 subjects) one, control measurement of HGF will be performed. Three days after ACS symptoms appeared, left ventricular function is determined by echocardiography. Scheduled control visits are performed after 3 months follow up. The demographic and clinical data, duration of chest pain, results of 12 leads ECG, angiographic findings, haemodynamic description of cardiac function (parameters from echocardiography and ventriculography), type of invasive revascularisation and results of performed measurements and examinations will undergo single and multivariable statistical analysis. Additionally, according to a few clinical and angiographic findings for statistic analysis will be specified either:
subgroup of patients with "major myocardial injury" which will comprise patients with anterior or antero-lateral myocardial infarction (MI) with occlusion or significant left anterior descending (LAD) branch stenosis and/or multivessel disease,
subgroup of patients with "moderate myocardial injury" which will consist of patients with inferior and/or posterior MI and with singlevessel disease but not LAD,
subgroup of patients with "minor myocardial injury" which will include patients with NSTE-ACS (Non-ST-Segment Elevation ACS) and without a significant increase of myocardial injury markers.

Where is the study taking place?
The record lists 1 site in Poland. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Composite end point of the study which consists of: death, myocardial infarction, exacerbation of angina, heart failure, cardiovascular reintervention, rehospitalization due to cardiovascular reasons, stroke (time frame: 3 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00844987, which also lists 3 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 May 2010.
