Study Type : Observational
Estimated Enrollment : 200 participants
Observational Model: Cohort
Time Perspective: Prospective
Official Title: Analysis of Proteome and Pathophysiological Characteristics of Human Blood Cells
Study Start Date : July 2012
Estimated Primary Completion Date : December 2019
Estimated Study Completion Date : December 2019

100 healthy volunteers in age of 20-75 years
100 patients with stable coronary artery disease and accordingly endothelial dysfunction

Primary Outcome Measures :
  1. Blood examination [ Time Frame: baseline ]

    Following parameters will be examined:

    • Blood count (red cells, white cells, platelets, hemoglobin, hematocrit, mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), red blood cell distribution width (RDW), mean platelet volume (MPV) )
    • Creatinin
    • Urea
    • Glucose
    • Glycated hemoglobin (HbA1c)
    • Cholesterol
    • Triglyceride
    • C-reactive Protein
    • Apolipoprotein

Secondary Outcome Measures :
  1. Protein expression [ Time Frame: baseline ]
    Determination with western blot

  2. Asymmetric dimethylarginine (ADMA) and Cytokine [ Time Frame: baseline ]
    Determination with enzyme-linked immunosorbent assay (ELISA).

  3. Microparticles [ Time Frame: baseline ]
    Determination with ELISA and flow cytometry

  4. Immunocytochemistry [ Time Frame: baseline ]
  5. Nitric oxid metabolite and proteins in blood plasma, red blood cells and peripheral blood mononuclear cells (PBMN) [ Time Frame: baseline ]
    Determination with reductive chemiluminescence

  6. Nitric oxid and reactive oxygen species [ Time Frame: baseline ]
    Determination with fluorescence coloring in flow cytometry and fluorescence microscopy
