Selected inflammatory markers in patients with acute coronary syndrome

: The aim of the study was the assessment of selected inflammatory markers in patients with stable and unstable angina pectoris, in comparison to patients with dyslipidemia without coronary artery disease. The study group included 61 patients (37-79 years old), divided into three subgroups: group I. 26 (43%) with unstable angina, group 2. 19 (26%) with stable angina, group III. 16 (26%) dyslipidemia without coronary artery disease. We measured serum levels of cytokines (IL-1B, IL-1Ra, IL-2, IL-6, TNF-alpha), immunoglobulins (IgG, IgE, IgM), fibrinogen. C-reactive protein and subclass of lymphocytes T CD4 and T CD8. In stable and unstable angina pectoris group we found lower percentage of T CD4, T CD8 and higher level of TNF-alpha. In unstable angina group the level of IL-1 beta was lower and the concentration of C-reactive protein, IgE was higher in comparison to group without coronary artery disease. Observed immunoregulatory disorders confirm immune mechanism in the origin of unstable angina pectoris.
