Brief Summary:
The investigators sought to assess whether plasma myeloperoxidase (MPO) levels differ among patients with stable and unstable CAD patients and control subjects, and correlate with inflammatory and clinical risk factors such as ox-LDL, NO,leptin, adiponectin, sPLA2, Lp-PLA2, homocysteine and 3-nitrotyrosine in the patients.

Condition or disease
Coronary Artery Disease

Detailed Description:
Elevation of the leukocyte enzyme myeloperoxidase (MPO) in stable coronary artery disease (CAD) patients in contrast to unstable CAD patients is controversial and its relationship with some inflammatory and noninflammatory markers such as oxidized LDL (ox-LDL) and nitric oxide (NO) in the CAD patients has not been evaluated yet. Evaluation of these relationships is the aim of the study.Also the relationships between MPO and some other inflammatory biomarker such as leptin, adiponectin, sPLA2, Lp-PLA2, homocysteine and 3-nitrotyrosine are examined. This study includes 50 stable CAD, 50 unstable CAD patients and 50 controls. Plasma MPO, ox-LDL, leptin, adiponectin, sPLA2 levels are determined using enzyme immunoassay.Homocysteine and 3-nitrotyrosine are measured using HPLC-fluorescence method. Plasma total NO and other risk factors such as lipid profile, hypertension, smoking, diabetes mellitus and familial history of CAD are also determined in the patients. Results are statistically analysed and the association between all markers are assessed.
