Insights
This study found that patients with stable and unstable angina pectoris exhibit distinct inflammatory marker profiles, including altered T-cell subsets and elevated tumor necrosis factor-alpha (TNF-α). Unstable angina specifically showed higher C-reactive protein and immunoglobulin E (IgE) levels, suggesting immune dysregulation.
Area of Science:
- Cardiology
- Immunology
- Biochemistry
Background:
- Angina pectoris, a symptom of coronary artery disease (CAD), is linked to inflammatory processes.
- Dyslipidemia is a major risk factor for CAD and may involve inflammatory pathways.
- Understanding inflammatory markers in different stages of angina and in dyslipidemia is crucial for disease management.
Purpose of the Study:
- To compare inflammatory markers in patients with stable angina, unstable angina, and dyslipidemia without CAD.
- To investigate the role of cytokines, immunoglobulins, fibrinogen, C-reactive protein, and T-lymphocyte subsets in these conditions.
Main Methods:
- Serum levels of cytokines (IL-1β, IL-1Ra, IL-2, IL-6, TNF-α), immunoglobulins (IgG, IgE, IgM), fibrinogen, and C-reactive protein were measured.
- T-lymphocyte subsets (CD4 and CD8) were quantified.
- Patients were categorized into three groups: unstable angina (n=26), stable angina (n=19), and dyslipidemia without CAD (n=16).
Main Results:
- Patients with stable and unstable angina showed a lower percentage of T CD4 and T CD8 lymphocytes and a higher level of TNF-α compared to the control group.
- In the unstable angina group, lower IL-1β levels and higher concentrations of C-reactive protein and IgE were observed compared to the group without CAD.
- These findings indicate significant immunoregulatory differences across the studied patient groups.
Conclusions:
- Immunoregulatory disorders are evident in patients with angina pectoris, particularly unstable angina.
- The observed alterations in inflammatory markers support an immune-mediated mechanism in the pathogenesis of unstable angina.
- Further research into these immune mechanisms could lead to novel therapeutic strategies for angina.
Abstract:
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.
