Plasma fibrinogen is not measured routinely in clinical practice for p
rediction of cardiovascular disease (CVD) but further modest advances
in the research investigating fibrinogen and CVD may make this a reali
ty. First, agreement must be reached on the most appropriate method of
measurement in clinical practice taking account of the type of fibrin
ogen to be assayed, the sources and degree of measurement variability,
the development of standards and the financial costs. Secondly, furth
er information is required on the value of plasma fibrinogen as a usef
ul risk marker in the primary and secondary prediction of future cardi
ovascular events. There is a need to express risks in a format which i
s useful to the general public and to clinicians, and which takes acco
unt of associated risks of cigarette smoking, blood pressure, and seru
m lipids. Finally, the effectiveness of lowering plasma fibrinogen lev
els in patients with CVD is not yet established. Fibrate drugs are war
ranted in patients with high-risk lipid profiles, but their effects on
cardiovascular outcome due to lowering of plasma fibrinogen await the
results of current randomized trials.
