Summary:
Objective: To describe relations among postmenopause, hormonal therapy, lipid metabolism and risk of
cardiovascular diseases.
Design: Search and analysis of relevant data from medical literature.
Methods: Analysis of the relation between serum lipid profile and postmenopausal changes, evaluation of
positive and negative effects of estrogens on vascular wall and lipid metabolism, analysis of methods for
the assessment of cardiovascular risk and evaluation of recent guidelines.
Results: Postmenopause is connected with significant changes in lipid metabolism, serum lipid profile and
with increased risk of cardiovascular diseases. Deficit of estrogens influences lipid metabolism negatively.
However, estrogen substitution has both positive and negative effects on vascular wall. Negative
effects are: increased occurence of postprandial hyperlipidemia with increased triglycerides, generation
of aterogenous small dense LDL particles, increased risk of inflammatory changes in vascular wall and
procoagulation situation.
Conclusion: Hormonal therapy can display some positive effects of vascular wall. However, recent data
evaluate hormonal substitution with regard to atherosclerosis and cardiovascular problems as less benefitial
or even risky.
Key words:
postmenopause, lipid profile, hormonal substitution, atherosclerosis, cardivasular diseases
