AHJ：乳房切除术并不增加心脏病风险

与一些最初研究课题也就是说，一项新的新泽西州研究课题辨认出中都年成年人透过内膜输精管（；还有或不；还有乳腺动手术）后，心血管疾病的确实会都未升高。这些成年人炎症性的确实会却是高于共存绝经的成年人，该新研究课题说道。

堪萨斯城该大学首席作家Karen A. Matthews及熟人在一份报告中都写下了他们的辨认出，这份报告计划于本周在线公布于《新泽西州心肌梗塞学会刊物》。

Matthews，堪萨斯城的一位杰出的心理疾病教授和流行病学与人类学教授，在一份公报中都声明，这些结果对正在考虑内膜输精管的中都年成年人来说道应该是毫无疑问的：

“研究课题结果表明，相对于共存绝经后，内膜输精管后的炎症性确实会生物体水平不大确实升高，”Matthews说道。

内膜输精管与炎症性确实会

内膜输精管是一种类似的移除成年人内膜的手术后操作方法。有时，患者还移除乳腺，以降低乳腺癌确实会。

有时确实显著需要透过该操作方法，比如因为肝癌、内膜下垂、纤维由此可知肌瘤，或因为非常较重的月经过多与痛经，但与此同时，和所有手术后一由此可知，仍要权衡其获利与确实会。

因为雄激素转变，在绝经从前透过内膜输精管常引发来得年期提从前。

一些最初研究课题表明内膜输精管减低心血管疾病的仍然确实会，而心血管疾病是成年人头号杰森。而且他们推断，如果同时动手术乳腺，该确实会将来得高。

但是该见解有缺陷，主要因为这些研究课题倾向于评估内膜输精管与/或乳腺输精管多年最后的炎症性确实会，而并未将她们在手术后之从前就确实有的确实会考虑上去。

研究课题者们做到了什么

而在该项新研究课题中都，Matthews及其熟人随访了3,302位新泽西州绝经从前成年人11年。这些成年人参加了全国成年人研究课题（SWAN）。

研究课题伊始，当这些成年人加入到SWAN时，她们42-52岁，内膜完整，有至少1个乳腺，且并未使用激素疗法。

在随访期间，每年给她们做到评估。在此期间，大部分成年人超越共存绝经成年，一些透过了内膜输精管；还有乳腺输精管，而一些则不；还有乳腺输精管。

透过内膜输精管的主要原因是纤维由此可知肌瘤、月经过多和慢性骨盆痛。

研究课题者在内膜输精管从前后评估了参加者的炎症性确实会，并将这些数据与那些共存绝经的成年人最后一次月经从前后的确实会相对来说。

Matthews及其熟人说道，他们的研究课题是首项多民族研究课题，了透过内膜输精管与共存绝经的成年人的炎症性确实会生物体的每年预期转变。

辨认出了什么

该归纳显示内膜输精管从前后与共存绝经从前后心血管确实会生物体直接影响，在各不相同母体，内膜输精管者与共存绝经者变化模式大相径庭；同时，整体而言变化模式显示内膜输精管者心血管确实会都未升高，研究课题者们说道。并且，此上述情况在所有种族组都一由此可知。

并且，即使在调整确实的影响生物体——比如体液质量指数（BMI）——最后，上述情况仍一由此可知。内膜输精管；还有乳腺输精管后，BMI确实有所升高。

原因是什么

Mathews说道他们却是相符为什么他们的辨认出与显示内膜输精管下降时炎症性确实会的最初研究课题各不相同。

一个原因确实是，他们并未将年轻成年人归属于研究课题，而来得早透过内膜输精管引发的炎症性确实会来得高。

另一个原因，Matthews说道，确实是因为该研究课题排除了因为肝癌而透过内膜输精管的成年人。

SWAN由国家老年医学研究课题所、国立保健研究课题所、国立医疗保健研究课题院、成年人健康研究课题室和补充与替代医学中都心共同发起。

2011年，《内医学档案》刊物写道，来自旧金山加利福尼亚该大学的研究课题者们美联社，他们辨认出透过了内膜输精管；还有乳腺输精管的成年人再次发生乳腺癌的确实会降低，并且再次发生其它类型肝癌、心肌梗塞或髋骨引的确实会都未下降时。

原意书本：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."
