AHJ：子宫切除术并不增加心脏病发风险

与一些早期比对相反，一项更进一步新的泽西州比对发现中会年未婚顺利完成睾丸外科手术术（友或不友卵巢外科手术）后，乳癌的显然会并未上升。这些未婚哮喘的显然会十分高于纯净绝经的未婚，该新的比对说。

堪萨斯城大学首席作家Karen A. Matthews及同事在一份年度报告中会写下了他们的发现，这份年度报告计划于本周在线发布于《新的泽西州心脏病发学会新闻周刊》。

Matthews，堪萨斯城的一位杰出贡献的精神病学教授和流行病学与人类学教授，在一份新的闻公报中会声明，这些结果对早就再考虑睾丸外科手术术的中会年未婚来说应该是无疑的：

“比对结果表明，比起纯净绝经后，睾丸外科手术术后的哮喘显然会位点水平不大显然上升，”Matthews说。

睾丸外科手术术与哮喘显然会

睾丸外科手术术是一种常见的替换未婚睾丸的外科手术操作。有时，病人还替换卵巢，以提高卵巢癌显然会。

有时显然显着须要顺利完成该操作，比如因为乳腺癌、睾丸下垂、细丝所发肌瘤，或因为十分重的月经过多与不止经，但与此同时，和所有外科手术一所发，仍要取舍其盈余与显然会。

因为荷尔蒙彻底改变，在绝经当年顺利完成睾丸外科手术术常随之而来青春期提当年。

一些早期比对表明睾丸外科手术术提高乳癌的长期显然会，而乳癌是未婚头号杀手。而且他们推断，如果同时外科手术卵巢，该显然会将更高。

但是该论调有缺陷，主要因为这些比对倾向于检验睾丸外科手术术与/或卵巢外科手术术多年在此之后的哮喘显然会，而没有将她们在外科手术之当年就显然有的显然会再考虑进去。

比对者们做到了什么

而在该项新的比对中会，Matthews及其同事随访了3,302位新的泽西州绝经当年未婚11年。这些未婚参加了全国未婚比对（SWAN）。

比对伊始，当这些未婚加入到SWAN时，她们42-52岁，睾丸完整，有有数1个卵巢，且没有使用激素疗法。

在随访期间，每年给她们做到检验。从那时起，大部分未婚达到纯净绝经年龄，一些顺利完成了睾丸外科手术术友卵巢外科手术术，而一些则不友卵巢外科手术术。

顺利完成睾丸外科手术术的主要显然是细丝所发肌瘤、月经过多和慢性骨盆不止。

比对者在睾丸外科手术术当年后检验了参与者的哮喘显然会，并将这些数据库与那些纯净绝经的未婚仍要一次月经当年后的显然会相比。

Matthews及其同事说，他们的比对是首项多汉民族比对，了顺利完成睾丸外科手术术与纯净绝经的未婚的哮喘显然会位点的每年预想彻底改变。

发现了什么

该比对结果显示睾丸外科手术术当年后与纯净绝经当年后高血压显然会位点频发变化，在不同幼体，睾丸外科手术术者与纯净绝经者变化来进行并不相同；同时，总体变化来进行结果显示睾丸外科手术术者高血压显然会并未上升，比对者们说。并且，此上述情况在所有群体组都一所发。

并且，即使在更改显然的阻碍位点——比如体液质量指数（BMI）——在此之后，上述情况仍一所发。睾丸外科手术术友卵巢外科手术术后，BMI确实大为上升。

显然是什么

Mathews说他们十分确定为什么他们的发现与结果显示睾丸外科手术术升高哮喘显然会的早期比对不同。

一个显然显然是，他们没有将年轻未婚划入比对，而更早顺利完成睾丸外科手术术随之而来的哮喘显然会更高。

另一个显然，Matthews说，显然是因为该比对排除了因为乳腺癌而顺利完成睾丸外科手术术的未婚。

SWAN由各地区老年医学比对所、国立护理比对所、国立卫生比对院、未婚卫生比对室和不足之处与替代医学中会心携手倡议。

2011年，《内物理档案》新闻周刊所写，来自芝加哥耶鲁大学的比对者们美联社，他们发现顺利完成了睾丸外科手术术友卵巢外科手术术的未婚频发卵巢癌的显然会提高，并且频发其它类型乳腺癌、心脏病发或髋骨后下的显然会并未升高。

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."
