| abstractText | OBJECTIVE: Elevated fibrinogen is correlated with severe atherosclerosis, as defined by the occurrence of ischemic events, but the mechanistic basis for this correlation remains unknown. To study this relationship, we examined spontaneous and diet-induced atherosclerosis in transgenic mice with hyperfibrinogenemia (elevated fibrinogen). METHODS AND RESULTS: Normal and transgenic mice were fed either an atherogenic diet or simple breeder chow. We measured plasma fibrinogen levels and identified an age-dependent and diet-dependent increase in fibrinogen. After 8 to 12 months, aortic sections were prepared and stained, and lipid-containing lesions were counted, measured, and assessed for maturity. Lipid-filled deposits appeared spontaneously in a small number of mice on breeder chow; typical fatty streak-type lesions appeared in almost all of the diet-fed animals. Morphometric analysis showed that neither the number nor the size of lesions was influenced by either fibrinogen level or genotype. CONCLUSIONS: Our data showed that neither fibrinogen concentration nor genotype had a statistically significant effect on the initiation, initial growth, or early progression of atherosclerotic lesions. |
