Could Tumor Necrosis Factor Serve as a Marker for Cardiovascular Risk Factors and Left Ventricular Hypertrophy in...

Area of Science:

• Cardiovascular Medicine
• Immunology
• Metabolic Disorders

Background:

• Cardiomyocyte production of Tumor Necrosis Factor (TNF), a pro-inflammatory cytokine, contributes to myocardial metabolic disorders.
• Coronary Artery Disease (CAD) in younger individuals presents unique challenges in risk assessment.

Purpose of the Study:

• To investigate the association between plasma TNF levels and cardiovascular disease risk factors.
• To explore the relationship between TNF and cardiac morphology parameters in young CAD patients.

Main Methods:

• Plasma TNF concentrations were quantified using ELISA assays.
• Echocardiography and electrocardiography were performed on all participants.
• The study included 75 men (≤50 years) and 25 women (≤55 years).

Main Results:

• Positive correlations were found between TNF and BMI, weight, waist, and hip circumference.
• Negative correlations linked TNF to HDL and ApoA levels; positive correlations with ApoB/ApoA1 ratio, Apo B, IL6, LDL, and TG.
• Higher TNF levels were associated with metabolic syndrome components, including dyslipidemia, and potentially impaired diastolic function.

Conclusions:

• Plasma TNF levels show a significant association with metabolic syndrome and dyslipidemia in young CAD patients.
• TNF may serve as a diagnostic marker for certain risks in CAD patients.
• TNF measurement is not a suitable surrogate for echocardiography in assessing cardiac function.
