Abstract
The passage of the menopause has been reported to be followed by a steadily increasing
risk of cardio-vascular disease (CVD). Changes in the concentrations of certain coagulation
factors and fibrinolytic components are considered risk factors for CVD. We evaluated
the differences in some of these variables between a premenopausal group (A) n = 28) and two postmenopausal groups, one of women less than 18 months past the menopause
(B) n = 28), the other of women more than 18 months past the menopause (C) n = 21). The variables measured were serum oestradiol content, plasma antithrombin
III (AT III) activity, protein C activity and the plasma concentrations of tissue
type plasminogen activator (t-PA) antigen, plasminogen activator inhibitor (PAI-I)
antigen, and fibrinogen. As compared with the premenopausal women (group A), group
C showed significantly higher values for AT III and protein C activity and for t-PA
and PAI-I antigen; and group B and C both showed significantly higher fibrinogen concentrations.
This probably means that haemostatic balance was maintained in the postmenopausal
women, although the increased concentrations of fibrinogen and PAI-1 might constitute
risk factors for the development of cardiovascular disease.
