[Characteristics of autoimmune reactions in chronic cardiac failure of different etiology]
Insights
Patients with chronic cardiac failure (CCF) show distinct autoimmune reactions. Dilated cardiomyopathy (DCMP) patients exhibit higher antimyocardial autoantibodies, indicating more severe inflammation than in coronary heart disease (CHD).
Area of Science:
- Cardiology
- Immunology
- Internal Medicine
Context:
- Chronic cardiac failure (CCF) encompasses various etiologies, including coronary heart disease (CHD) and dilated cardiomyopathy (DCMP).
- Autoimmune reactions are increasingly recognized as contributing factors in the pathogenesis and progression of CCF.
- Understanding immune system involvement is crucial for managing complex cardiac conditions.
Purpose:
- To investigate and compare autoimmune responses in patients with CCF of different origins.
- To characterize the relationship between autoimmune markers and disease severity in CHD and DCMP.
- To identify specific immune activation patterns associated with cardiac dysfunction.
Summary:
- This study measured immune activation markers in 43 patients with CHD and 44 with DCMP.
- Higher titers of antimyocardial autoantibodies were observed in DCMP patients compared to CHD patients.
- In CHD, inflammation severity correlated with endothelial and ventricular dysfunction.
Impact:
- Findings suggest that specific autoimmune reactions influence the severity of chronic cardiac failure.
- This research highlights the role of autoimmunity in differentiating CCF progression between CHD and DCMP.
- Results may inform targeted immunomodulatory therapies for specific CCF subtypes.
Aim:
To characterize autoimmune reactions in patients with chronic cardiac failure (CCF) of different etiology.
Material And Methods:
Basic markers of immune activation were measured in 43 patients with coronary heart disease stage I-IIB (NYHA FC I-IV) and 44 patients with dilated cardiomyopathy (DCMP) stage I-IIB (NYHA FC I-IV). Antibodies to myocardial tissue were studied with indirect immunofluorescence. Echocardiography was made by standard recommendations with evaluation of systolic and diastolic left ventricular function. Concentrations of C-reactive protein, IgG, IgA, IgM were estimated nephelometrically. Enzyme immunoassay studied serum levels of IL-8, IL-2R, IL-6, IL-18, IL-10, IFN-gamma, endothelin.
Results:
Patients with DCMP had higher titers of antimyocardial autoantibodies than in coronary heart disease (CHD) reflecting more severe autoimmune inflammation. In CHD endothelial, systolic and diastolic dysfunctions severity correlated with severity of inflammation.
Conclusion:
Some characteristics of autoimmune reactions in CCF determine severity of the disease course.
