  1. Fibrinogen plasma levels in an apparently healthy general population : Relation to environmental and genetic determinants.

    Article - En anglais

    Elevated fibrinogen levels are an independent risk factor for cardiovascular ischemic disease.

    We investigated the relationship between cardiovascular ischemic risk factors, the fibrinogen Bbêta-chain G/A-455 polymorphism and plasma fibrinogen levels in 989 apparently healthy subjects.

    Fibrinogen values were higher in subjects with C reactive protein (C-RP)>0.33 mg/dl, BMI>23.9 kg/m2, total cholesterol>4.84 mmol/l, triglycerides>1.02 mmol/l, PAI-1 antigen>12.2 ng/ml, carriers of the A allele, first-degree relative history of coronary artery disease, or consuming>10 cigarettes per day (p<0.01).

    Men and ethanol drinkers showed lower plasma fibrinogen levels (p<0.01).

    The multivariate analysis confirmed the independent effect of C-RP, age, BMI, total cholesterol, gender, PAI-1, - 455 G/A polymorphism, (p<0.05).

    BMI, total cholesterol, PAI-1, alcohol and smoking habit raised with the increase of age and differed between sexes.

    The A-455 allele increasing effect was significant in women, especially in subjects aged<30 years, and in men aged<43 years.

    These results indicate that environmental factors contributed to a larger extent to fibrinogen variability, whereas the A-455 allele was associated with a steeper increase in younger age quartiles.
