  • Title: The impact of hormone replacement therapy on the pathophysiology of peripheral arterial disease.
    Author: Davies RS, Vohra RK, Bradbury AW, Adam DJ.
    Journal: Eur J Vasc Endovasc Surg; 2007 Nov; 34(5):569-75. PubMed ID: 17681824.
    Abstract:
    BACKGROUND: Hormone replacement therapy (HRT) is recommended to post-menopausal women to control menopausal symptoms and prevent osteoporosis. The management of women with peripheral arterial disease (PAD) and who are taking HRT is controversial. AIM: To summarise what is known about HRT and its effect on the natural progression of PAD and its subsequent treatment. METHODS: A MEDLINE (1966-2004) and Cochrane library search for articles relating to HRT and PAD was undertaken. RESULTS: The potential benefits of unopposed estrogen therapy on atherosclerotic progression and limb microcirculation are outweighed by the increased risk of endometrial dysplasia and thrombotic complications. Only one major study (Rotterdam) specifically assessed the impact of HRT on the clinical course of PAD. The findings suggested a decreased risk of PAD among healthy post-menopausal women taking HRT which contrasts with the sub-group analyses of other major studies (HERS/HERS II). HRT appears to reduce the primary success rates of both endovascular and open surgical revascularisation in patients with PAD. CONCLUSIONS: Further studies are required to investigate the effects of HRT on the progression of PAD and its management.
