Several studies have linked higher plasma fibrinogen and plasminogen activator inhibitor (PAI-1) concentrations with increased risk of cardiovascular disease.
We studied whether members of families with increased occurrence of coronary heart disease (CHD) have increased levels of fibrinogen and PAI-1 and whether subclinical carotid atherosclerosis is associated with these two hemostatic factors.
Contrary to our hypothesis, fibrinogen and PAI-1 antigen levels were not different between high CHD risk families versus random families.
Adjusted for age and family type, fibrinogen and PAI-1 were both associated positively with carotid intima-media thickness assessed by B-mode ultrasound.
However, adjustment for lifestyle and medical covariates essentially eliminated these associations.
These data suggest 1) elevated fibrinogen and PAI-1 do not explain clustering of CHD in families and 2) fibrinogen and PAI-1 may partly mediate the effects of other risk factors on carotid atherosclerosis, though the data are also consistent with them playing no causal role.
