Insights
Cardiovascular disease (CVD) is a major concern for postmenopausal women. Hormone therapy (HT) may offer benefits, but its use requires individualized assessment due to complex cardiovascular risk factors.
Area of Science:
- Cardiology
- Endocrinology
- Women's Health
Background:
- Cardiovascular disease (CVD) is the leading cause of death for women in Taiwan, particularly postmenopausal women.
- Menopause-related estrogen deficiency is linked to increased CVD risk, with coronary artery disease and stroke being primary concerns.
- Previous observational studies suggested hormone therapy (HT) reduces coronary artery disease risk.
Purpose of the Study:
- To review the current understanding of cardiovascular disease risk in postmenopausal women.
- To evaluate the efficacy and risks of hormone therapy (HT) for cardiovascular disease (CVD) prevention.
- To emphasize the need for individualized treatment decisions regarding HT in postmenopausal women.
Main Methods:
- Review of observational studies and randomized controlled trials on hormone therapy (HT) and cardiovascular disease (CVD) prevention.
- Analysis of the effects of estrogen and HT on lipid profiles and cardiovascular risk factors.
- Discussion of the multifactorial nature of CVD development and progression.
Main Results:
- Randomized controlled trials have raised questions about the efficacy of HT for primary and secondary CVD prevention, despite its lipid-lowering effects.
- Estrogen deficiency post-menopause is a significant factor in CVD risk for women.
- The complex interplay of various factors in CVD genesis necessitates further research.
Conclusions:
- The role of HT in cardiovascular disease (CVD) prevention for postmenopausal women remains complex and requires further investigation.
- Individualized patient assessment is crucial when considering HT, weighing potential benefits against risks.
- Future research should focus on the efficacy of different HT preparations and dosages in at-risk postmenopausal women before significant atheromatous lesion development.
Abstract:
As in other Western countries, cardiovascular disease (CVD) is the leading cause of death among women in Taiwan, exceeding the mortality from cervical or breast cancer. Women generally present with CVD after menopause and later than men, since menopause-related estrogen deficiency has been considered to be associated with an increased risk for CVD. Thus, coronary artery diseases and stroke are the two main contributors of mortality among postmenopausal women. Observational studies have reported a reduction in coronary artery disease risk after hormone therapy (HT) ranging from 31-44%. However, recent randomized controlled trials that evaluated the effect of HT on primary and secondary CVD prevention have questioned the efficacy of HT, despite confirming the lipid-lowering effect of estrogen. However, a cluster of factors are responsible for the genesis and progression of CVD. Until we further evaluate their specific actions and how these different factors interact, the issue related to HT and cardiovascular risk will remain unsettled. Since these studies have contributed to our understanding of the benefits and risks associated with HT, HT use should be individualized after consideration of the condition of each postmenopausal patient. Ideally, the efficacy of different preparations and dosages of HT in postmenopausal women who are at risk of CVD, before atheromatous lesions have developed, should be investigated.
