[Cardial fibrosis and the functional activity of leukocytes in patients with essential arterial hypertension]

Area of Science:

• Cardiovascular Medicine
• Immunology
• Biochemistry

Background:

• Essential arterial hypertension (EAH) is a prevalent cardiovascular condition.
• Myocardial hypertrophy and cardiac fibrosis are significant complications of EAH.
• The role of inflammatory markers and cellular activity in EAH pathogenesis requires further elucidation.

Purpose of the Study:

• To investigate serum levels of TGF-beta1 and N-terminal peptide procollagen type III in EAH patients.
• To explore the association between these markers and clinical parameters of EAH.
• To determine the relationship between leukocyte activity, TGF-beta1, and cardiac function in EAH.

Main Methods:

• Serum analysis for TGF-beta1 and N-terminal peptide procollagen type III.
• Correlation analysis with disease duration, mean arterial pressure, and left ventricular hypertrophy.
• Assessment of leukocyte functional activity and its relation to diastolic function and TGF-beta1.

Main Results:

• Elevated serum levels of TGF-beta1 and N-terminal peptide procollagen type III were observed in EAH patients.
• These increases were associated with disease duration, mean arterial pressure, and left ventricular hypertrophy.
• Increased leukocyte functional activity correlated with impaired left ventricular diastolic function and higher TGF-beta1 levels.

Conclusions:

• Leukocytes may contribute to myocardial hypertrophy and cardiac fibrosis in EAH.
• Leukocyte activation, through cytokine and growth factor secretion, appears to play a role in EAH pathogenesis.
• TGF-beta1 and leukocyte activity are implicated in the development of cardiac remodeling in EAH.
