AHJ：子宫切除术并不上升心脏病风险

与一些年当年期研究工作相反，一项原先新泽西州研究工作推断出之当年年未婚开展阴囊手术（相伴或不相伴乳腺截肢）后，肥胖症的效用并未上升。这些未婚妇科的效用越来越加略高于共存绝经的未婚，该新研究工作感叹。

底特律大学总监作家Karen A. Matthews及老友在一份简报之当年写下了他们的推断出，这份简报计划于本周在线发布于《新泽西州心脏病学会杂志》。

Matthews，底特律的一位杰出的精神病学讲师和流行病学与精神分析讲师，在一份新闻公报之当年道歉信，这些结果对悄悄考虑阴囊手术的之当年年未婚来感叹一定会是赞美的：

“研究工作结果表明，相对于共存绝经后，阴囊手术后的妇科效用变异水平不大也许上升，”Matthews感叹。

阴囊手术与妇科效用

阴囊手术是一种常用的移走未婚阴囊的手术可用。有时，治疗还移走乳腺，以降低白血病效用。

有时也许明显需要开展该可用，比如因为白血病、阴囊下垂、外皮；也肌瘤，或因为越来越加重的迟于过多与痛经，但与此同时，和所有手术一；也，仍要权衡其收益与效用。

因为荷尔蒙改变，在绝经当年开展阴囊手术常造成越来越年期提当年。

一些年当年期研究工作表明阴囊手术降低肥胖症的长期效用，而肥胖症是未婚头号职业杀手。而且他们推断出，如果同时截肢乳腺，该效用将越来越佳。

但是该见解有缺陷，主要因为这些研究工作倾向于审核阴囊手术与/或乳腺手术多年不久的妇科效用，而很难将她们在手术之当年就也许有的效用考虑上去。

研究工作者们做了什么

而在该项新研究工作之当年，Matthews及其老友随访了3,302位新泽西州绝经当年未婚11年。这些未婚参加了省内未婚研究工作（SWAN）。

研究工作伊始，当这些未婚加入到SWAN时，她们42-52岁，阴囊完整，有至少1个乳腺，且很难用于激素麻醉药。

在随访期间，每年给她们做审核。在此期间，多数未婚达到共存绝经岁数，一些开展了阴囊手术相伴乳腺手术，而一些则不相伴乳腺手术。

开展阴囊手术的主要状况是外皮；也肌瘤、迟于过多和慢性脊柱痛。

研究工作者在阴囊手术当年后审核了组织者的妇科效用，并将这些数据与那些共存绝经的未婚最后一次迟于当年后的效用相比之下。

Matthews及其老友感叹，他们的研究工作是首项多民族研究工作，了开展阴囊手术与共存绝经的未婚的妇科效用变异的每年期望改变。

推断出了什么

该分析看出阴囊手术当年后与共存绝经当年后心血管疾病效用变异发生波动，在各不相同个体，阴囊手术者与共存绝经者波动来开展大不相同；同时，某种程度波动来开展看出阴囊手术者心血管疾病效用并未上升，研究工作者们感叹。并且，此情况下在所有种族组都一；也。

并且，即使在优化也许的影响变异——比如生物体能量密度指数（BMI）——不久，情况下仍一；也。阴囊手术相伴乳腺手术后，BMI其实有所上升。

状况是什么

Mathews感叹他们越来越加确定为什么他们的推断出与看出阴囊手术升高妇科效用的年当年期研究工作各不相同。

一个状况也许是，他们很难将年轻未婚划定研究工作，而越来越年当年开展阴囊手术造成的妇科效用越来越佳。

另一个状况，Matthews感叹，也许是因为该研究工作排除了因为白血病而开展阴囊手术的未婚。

SWAN由东欧国家老年医学研究工作所、国立护理研究工作所、国立卫生研究工作院、未婚肥胖研究工作室和不足之处与替代医学之当年心共同发起人。

2011年，《内科学资料库》杂志写道，来自旧金山加利福尼亚大学的研究工作者们报道，他们推断出开展了阴囊手术相伴乳腺手术的未婚发生白血病的效用降低，并且发生其它各种类型白血病、心脏病或髋骨折的效用并未升高。

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."
