Correlation between the microinflammatory state and left ventricular structural and functional changes in maintenance...

Area of Science:

• Nephrology
• Cardiology
• Inflammation Biology

Background:

• Maintenance hemodialysis (MHD) patients often exhibit a pro-inflammatory state.
• Cardiac complications are a leading cause of morbidity and mortality in MHD patients.
• The relationship between microinflammation and cardiac alterations in MHD requires further elucidation.

Purpose of the Study:

• To investigate the correlation between microinflammation and left ventricular structural/functional changes in MHD patients.
• To assess the association of specific inflammatory markers with cardiac parameters.

Main Methods:

• Study included 48 MHD patients and 30 healthy controls.
• Inflammatory markers (hs-CRP, IL-6, TNF-α) measured via ELISA.
• Left ventricular structure and function assessed by echocardiography.

Main Results:

• MHD patients showed significantly higher hs-CRP, IL-6, and TNF-α levels than controls.
• Significant increases in left atrial diameter, left ventricular dimensions, wall thickness, and LVMI observed in MHD patients.
• Reduced left ventricular ejection fraction (LVEF) noted in MHD patients.
• hs-CRP, TNF-α, and IL-6 correlated with LVMI; hs-CRP correlated with reduced LVEF.

Conclusions:

• A microinflammatory state is associated with structural and functional cardiac impairment in MHD patients.
• hs-CRP is a potential indicator of cardiac dysfunction in this population.
