Randomized trial examines the impact of fibrinogen deficiency on atherosclerosis in mice, suggesting minimal role in disease progression.

The aim is to investigate the role of fibrinogen in the development of atherosclerosis using Fib-deficient mice.
Fib-deficient mice were crossed with apo E-deficient mice to create a mouse model for atherosclerosis.
The study evaluated lesion development and complexity in both types of mice.
Analysis focused on lesion size and composition within the aortic tree.
Both apo E-/- and apo E-/-/Fib-/- mice developed lesions, including fatty streaks and fibrous plaques.
No significant difference in lesion size or complexity was observed between the two mouse groups.
Fibrinogen does not appear essential for the progression of advanced atherosclerosis despite its known associations with lipid metabolism.

Xiao et al. (1998) studied this question.
