AHJ：子宫切除术并不减低心脏病风险

与一些较晚期研究课题相反，一项最初美国研究课题应为出之前年妇女同步进行乳腺开刀（；还有或不；还有腺体开刀）后，哮喘疾病的几率未曾下跌。这些妇女儿科的几率相当高于大自然绝经的妇女，该原先研究课题说。

圣路易斯所大学首席散文家Karen A. Matthews及合作者在一份研究课题报告之前写就了他们的应为出，这份研究课题报告构想于本周应用软件发布于《美国肺炎学会刊物》。

Matthews，圣路易斯的一位杰出的心理学研究员和流行病学与心理学研究员，在一份原先闻公报之前单方面，这些结果对正要选择乳腺开刀的之前年妇女来说确实是鼓舞人心的：

“研究课题结果表明，一般而言大自然绝经后，乳腺开刀后的儿科几率突变素质不大可能下跌，”Matthews说。

乳腺开刀与儿科几率

乳腺开刀是一种罕见的移出妇女乳腺的治疗加载。有时，医护人员还移出腺体，以增加腺体癌几率。

有时可能明显无需同步进行该加载，比如因为前列腺癌、乳腺下垂、纤维的集肌瘤，或因为非常较重的月经过多与痛经，但与此同时，和所有治疗一的集，仍要权衡其收益与几率。

因为人体内忽略，在绝经前同步进行乳腺开刀常所致格外年期提前。

一些较晚期研究课题表明乳腺开刀提高哮喘疾病的长期几率，而哮喘疾病是妇女头号职业杀手。而且他们应为，如果同时开刀腺体，该几率将格外高。

但是该学说只不过，主要因为这些研究课题倾向于分析乳腺开刀与/或腺体开刀多年便的儿科几率，而不能将她们在治疗之前就可能有的几率选择进去。

研究课题者们好好了什么

而在该项原先研究课题之前，Matthews及其合作者随访了3,302位美国绝经前妇女11年。这些妇女参加了全国妇女研究课题（SWAN）。

研究课题在此之后，当这些妇女转入到SWAN时，她们42-52岁，乳腺非常简单，有最少1个腺体，且不能常用激素疗法。

在随访在此期间，每年给她们好好分析。在此在此期间，大部分妇女达到大自然绝经年龄，一些同步进行了乳腺开刀；还有腺体开刀，而一些则不；还有腺体开刀。

同步进行乳腺开刀的主要因素是纤维的集肌瘤、月经过多和慢性肋骨痛。

研究课题者在乳腺开刀前后分析了参与者的儿科几率，并将这些数据与那些大自然绝经的妇女最后一次月经前后的几率相比。

Matthews及其合作者说，他们的研究课题是历史性多少数民族研究课题，了同步进行乳腺开刀与大自然绝经的妇女的儿科几率突变的每年预计忽略。

应为出了什么

该分析辨识乳腺开刀前后与大自然绝经前后哮喘几率突变引发引发变化，在各不相同个体，乳腺开刀者与大自然绝经者引发变化方式也并不相同；同时，总体引发变化方式也辨识乳腺开刀者哮喘几率未曾下跌，研究课题者们说。并且，此情形在所有种族组都一的集。

并且，即使在调整可能的因素突变——比如药剂密度指数（BMI）——便，情形仍一的集。乳腺开刀；还有腺体开刀后，BMI可能有所下跌。

因素是什么

Mathews说他们相当确切为什么他们的应为出与辨识乳腺开刀升高儿科几率的较晚期研究课题各不相同。

一个因素可能是，他们不能将年青妇女归属于研究课题，而格外较早同步进行乳腺开刀所致的儿科几率格外高。

另一个因素，Matthews说，可能是因为该研究课题排除了因为前列腺癌而同步进行乳腺开刀的妇女。

SWAN由国家老年医学研究课题所、国立护理人员研究课题所、国立卫生研究课题院、妇女卫生研究课题室和补充与替代医学之前心共同发起。

2011年，《内科学档案》刊物写道，来自旧金山加利福尼亚所大学的研究课题者们媒体报道，他们应为出同步进行了乳腺开刀；还有腺体开刀的妇女引发腺体癌的几率增加，并且引发其它类别前列腺癌、肺炎或髋骨缩的几率未曾升高。

标题阅读：Hysterectomy does not increase risk of cardiovascular diseasePositive findings differ from previous studies on hysterectomy, heart disease riskHing a hysterectomy with or without ovary removal in mid-life does not increase a woman's risk of cardiovascular disease compared to women who reach natural menopause, contrary to many previously reported studies, according to research published online today in the Journal of the American College of Cardiology."Middle-aged women who are considering hysterectomy should be encouraged because our results suggest that increased levels of cardiovascular risk factors are not any more likely after hysterectomy relative to after natural menopause," said Karen A. Matthews, PhD, lead author of the study and a distinguished professor of psychiatry and professor of epidemiology and psychology at the University of Pittsburgh.Hysterectomy is the surgical removal of a woman's uterus; it is sometimes accompanied by the removal of the ovaries to decrease the risk of ovarian cancer. Hysterectomy is a common surgical procedure for women, but the benefits must be weighed against potential long-term related health consequences. Cardiovascular disease is the number one killer of women and many studies he shown increased risk of cardiovascular disease to be a health risk associated with hysterectomy, especially accompanied by ovary removal. Researchers in those studies usually evaluated cardiovascular disease risk factors years after hysterectomy and/or ovary removal and did not assess individual risk factor levels pre-surgery.For this study, investigators followed 3,302 premenopausal women between the ages of 42-52 for 11 years who were enrolled in the Study of Women's Health across the Nation (SWAN). Researchers compared cardiovascular disease risk factors in women prior to and following elective hysterectomy with or without ovary removal to the risk factors prior to and following final menstrual period in women who underwent natural menopause.This is the only multiethnic study that has tracked prospective annual changes in cardiovascular disease risk factors relative to hysterectomy or natural menopause.Investigators found that several cardiovascular disease risk factor changes differed prior to and following hysterectomy, compared to changes prior to and following a natural menopause, but those changes did not suggest an increased cardiovascular disease risk following hysterectomy, independent of body mass index, which did increase after hysterectomy with removal of ovaries. These effects were similar in all ethnic groups in the study.Dr. Matthews said it is unclear why this study's findings differed from other studies exploring hysterectomy and cardiovascular risk, but likely factors include the age of participants since hysterectomy that occurs earlier in life may present more cardiovascular risk. Also, earlier studies included women who had hysterectomy for any reason, whereas the SWAN study excluded women who had hysterectomy because of cancers. "This study will prove very reassuring to women who he undergone hysterectomy," said American College of Cardiology CardioSmart Chief Medical Expert JoAnne Foody, MD, FACC. "As with anything, if a woman is concerned about her risk for heart disease she should discuss this with her health care provider."
