Association of European population levels of thrombotic and inflammatory factors with risk of coronary heart disease:...

Area of Science:

• Cardiovascular Epidemiology
• Hemostasis and Thrombosis
• Inflammation Biology

Background:

• Established risk factors inadequately explain geographic variations in coronary heart disease (CHD) incidence.
• Thrombotic and inflammatory markers are implicated in cardiovascular disease pathogenesis.
• The WHO MONICA project provides a framework for investigating population-level health differences.

Purpose of the Study:

• To investigate the association between thrombotic and inflammatory markers and CHD event rates across diverse European populations.
• To identify potential novel risk factors that may explain international disparities in CHD risk.
• To assess the role of specific hemostatic and inflammatory markers in CHD etiology.

Main Methods:

• A substudy of the WHO MONICA project measured fibrinogen, von Willebrand factor (vWF), tissue plasminogen activator antigen, plasminogen activator inhibitor activity, fibrin D-dimer, plasma viscosity, C-reactive protein, and total cholesterol.
• Data were collected from men and women aged 45-64 years across 12 MONICA populations, primarily European.
• Standardized protocols and central analysis ensured data quality and comparability across 3996 subjects.

Main Results:

• Significant inter-population differences in thrombotic and inflammatory marker levels were observed, persisting after adjustment for age, body mass index, and smoking.
• Cross-sectional analyses revealed significant correlations between CHD event rates and vWF antigen (both sexes), nephelometric fibrinogen (men), and D-dimer (women).
• These findings suggest specific hemostatic markers contribute to CHD risk variations.

Conclusions:

• Von Willebrand factor (vWF), nephelometric fibrinogen, and D-dimer are identified as potential risk factors for coronary heart disease.
• These markers may play a crucial role in elucidating the differences in coronary risk observed between European populations.
• Further research into these thrombotic markers is warranted to refine CHD risk prediction models.
