Società Italiana per lo Studio dell’ Aterosclerosi Sez. Regionale Lombarda ESTROGEN REPLACEMENT IN POSTMENOPAUSAL WOMEN: NCEP RECOMMENDATIONS • Observational information suggests lower CHD risk in women on HRT • Experimental data suggests estrogen has beneficial effects on endothelial function • Oral estrogen can lower LDL-C and increase HDL-C • NCEP recommends that estrogen replacement can be used as alternative or adjunctive treatment to manage hypercholesterolemia in postmenopausal women.

Società Italiana per lo Studio dell’ Aterosclerosi Sez. Regionale Lombarda HERS RESULTS • No statistically significant difference between HRT • and placebo in both primary and secondary endpoints after 4 years. • Within first year, greater incidence in CHD events in HRT group. In years 3 and 4, lower CHD events in HRT group compared to placebo. • HRT lowered LDL 11% and increased HDL 10% compared to placebo. • Approximately 50% of randomized women were on lipid-lowering drugs. • Higher incidence of VTE and cholelithiasis in HRT group. JAMA 1998;280:605-613
CHD OUTCOMES DURING 6.8 YEARS OF HORMONE THERAPY (HERS II) • The higher risk of developing CHD in HERS was in the first two years of therapy. A decline occured between year 3 and 5. • HERS II was designed to verify whether the tendency to a reduction of CHD in HERS persisted in a longer follow up. • The HERS II study recruited 2.321 women (average 67 yearsof age) who gave their informed consent to continue therapy with the active drug or placebo.

CONCLUSIONS • Overall health risk exceeded benefits from use of combined estrogen+progestin for an average 5.2 year follow-up among healthy postmenopausal women • Risk for CHD was largely limited to the 1° year of therapy, whereas risk for Stroke and Venous Thromboembolism continued throughout the 5 years of therapy and may reflect prothrombotic and proinflammatory effects of progestins • Risk for breast cancer was associated with the duration of treatment • The risk-benefit profile of combined HRT is not consistent with the requirements for primary prevention of chronic diseases
