Abstract

In Brief Objective The general consensus has been that estrogen is invariably a risk factor for ischemic stroke (IS). We reviewed new observational studies that challenge this simple conclusion. Methods This was a review of observational studies of the association of premature or early menopause with stroke or IS published in English from 2006 through 2010. Results Three cohort studies showed an increased risk of all types of stroke in women who underwent bilateral oophorectomy compared with women who conserved their ovaries before age 50 years. The increased risk of stroke was reduced by hormone therapy in one of the studies, suggesting that estrogen deprivation is involved in the association. Four additional observational studies showed an association of all types of stroke or IS with the early onset of menopause or with a shorter life span of ovarian activity. In three of the seven studies, the association was restricted to IS. Age at menopause was more important than type of menopause (natural vs induced). Conclusions The findings from seven recent observational studies challenge the consensus that estrogen is invariably a risk factor for IS and can be reconciled by a unifying timing hypothesis. We hypothesize that estrogen is protective for IS before age 50 years and may become a risk factor for IS after age 50 years or, possibly, after age 60 years. These findings are relevant to women who experienced premature or early menopause or to women considering prophylactic bilateral oophorectomy before the onset of natural menopause. The findings from seven recent observational studies challenge the consensus that estrogen is invariably a risk factor of ischemic stroke. In this study, a unifying theory is proposed, in which estrogen is protective before approximately age 50 years and may become a risk factor of ischemic stroke after age 50 years or, possibly, after age 60 years.

  • Treatment with estrogens until age 45 years or longer may reduce the risk of cardiovascular disease and mortality.

    “Treatment with estrogens until age 45 years or longer may reduce the risk of cardiovascular disease and mortality (47,49,51).”

    From Hormonal Replacement in Hypopituitarism in Adults: An Endocrine Society Clinical Practice Guideline (2016) · cites this paper as [49]

    The Results (Findings from individual studies; page unavailable) report that women who had bilateral oophorectomy before age 45 and received hormone therapy through age 45 did not have increased cardiovascular-disease risk, and suggest that premature estrogen deficiency may explain increased cardiovascular mortality. This supports a possible benefit, but the evidence concerns women with early bilateral oophorectomy and cardiovascular mortality—not a general reduction in mortality for everyone treated with estrogen until age 45 or longer.

  • Treatment with estrogens through age 45 years or longer may reduce the risk of cardiovascular disease and mortality.

    “Treatment with estrogens through age 45 years or longer may reduce the risk of cardiovascular disease and mortality (47,49,51).”

    From Hormonal Replacement in Hypopituitarism in Adults: An Endocrine Society Clinical Practice Guideline (2016) · cites this paper as [49]

    The Results (Findings from individual studies; page unavailable) report that women who underwent bilateral oophorectomy before age 45 and received hormone therapy through age 45 did not have an increased risk of cardiovascular disease, including stroke. The paper also suggests that premature estrogen deficiency may explain increased cardiovascular mortality. The claim omits that population restriction and does not specify cardiovascular mortality; the paper does not establish a reduction in mortality generally. (LLM, conf=0.83)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
