AHJ：子宫手术并不增加心脏病风险

与一些年前期科学知识研究相反，一项新的宾夕法尼亚州科学知识研究推断出落魄女同性恋开展卵巢输卵管（友或不友输卵管外科手术）后，慢性病的安全性并未上升。这些女同性恋儿科的安全性并不一定优于自然现象绝经的女同性恋，该新科学知识研究说道。

匹兹堡该大学总监诗人Karen A. Matthews及老友在一份简报中所写成了他们的推断出，这份简报计划于本周在线发布于《宾夕法尼亚州心脏病发学会时代周刊》。

Matthews，匹兹堡的一位杰出的精神病学名誉教授和药理学与心理学名誉教授，在一份文告中所声明，这些结果对即将慎重考虑卵巢输卵管的落魄女同性恋来说道不该是鼓舞人心的：

“科学知识研究结果得出结论，相对于自然现象绝经后，卵巢输卵管后的儿科安全性特异性技术水平不大也许上升，”Matthews说道。

卵巢输卵管与儿科安全性

卵巢输卵管是一种常见的替换成女同性恋卵巢的手术加载。有时，病童还替换成输卵管，以降低输卵管癌安全性。

有时也许明显需要开展该加载，比如因为肝癌、卵巢下垂、纤维样肌瘤，或因为更为重的月经过多与痛经，但与此同时，和所有手术一样，仍要权衡其利息与安全性。

因为雌激素改变，在绝经前开展卵巢输卵管常造成了越来越年期延后。

一些年前期科学知识研究得出结论卵巢输卵管提高慢性病的长期安全性，而慢性病是女同性恋头号杀手。而且他们推断，如果同时外科手术输卵管，该安全性将越来越高。

但是该论点有缺陷，主要因为这些科学知识研究保守于安全性评估卵巢输卵管与/或输卵管输卵管多年之后的儿科安全性，而没有人将她们在手术前就也许有的安全性慎重考虑进去。

科学知识研究者们来作了什么

而在该项新科学知识研究中所，Matthews及其老友随访了3,302位宾夕法尼亚州绝经前女同性恋11年。这些女同性恋参与了全国女同性恋科学知识研究（SWAN）。

科学知识研究伊始，当这些女同性恋加入到SWAN时，她们42-52岁，卵巢完整，有多于1个输卵管，且没有人使用激素麻醉药。

在随访期间，每年给她们来作安全性评估。年初，部分女同性恋降到自然现象绝经年龄，一些开展了卵巢输卵管友输卵管输卵管，而一些则不友输卵管输卵管。

开展卵巢输卵管的主要也许是纤维样肌瘤、月经过多和慢性骨盆痛。

科学知识研究者在卵巢输卵管前后安全性评估了举例来说的儿科安全性，并将这些图表与那些自然现象绝经的女同性恋最后一次月经前后的安全性相比。

Matthews及其老友说道，他们的科学知识研究是首项多民族科学知识研究，了开展卵巢输卵管与自然现象绝经的女同性恋的儿科安全性特异性的每年意味著改变。

推断出了什么

该分析说明了卵巢输卵管前后与自然现象绝经前后缺血性安全性特异性频发叠加，在各不相同个体，卵巢输卵管者与自然现象绝经者叠加方式而大不相同；同时，总体叠加方式而说明了卵巢输卵管者缺血性安全性并未上升，科学知识研究者们说道。并且，此状况在所有白种人组都一样。

并且，即使在调整也许的阻碍特异性——比如消化道质量指数（BMI）——之后，状况仍一样。卵巢输卵管友输卵管输卵管后，BMI其实大大上升。

也许是什么

Mathews说道他们并不一定确定为什么他们的推断出与说明了卵巢输卵管增高儿科安全性的年前期科学知识研究各不相同。

一个也许也许是，他们没有人将年长女同性恋纳入科学知识研究，而越来越年前开展卵巢输卵管造成了的儿科安全性越来越高。

另一个也许，Matthews说道，也许是因为该科学知识研究排除了因为肝癌而开展卵巢输卵管的女同性恋。

SWAN由国家老年医学科学知识研究员、国立保健科学知识研究员、国立卫生科学知识研究院、女同性恋健康科学知识研究室和必需与替代医学中所心共同发起。

2011年，《内科学知识档案》时代周刊所述，来自旧金山加利福尼亚该大学的科学知识研究者们新闻报道，他们推断出开展了卵巢输卵管友输卵管输卵管的女同性恋频发输卵管癌的安全性降低，并且频发其它类型肝癌、心脏病发或髋骨折的安全性并未增高。

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."
