AHJ：子宫切除术非常增加心脏病风险

与一些更早研究成果相反，一项一新美国政府研究成果找到当同龄女同性恋同步进行腹腔抽脂（喜或不喜腹腔摘除）后，肾脏疾病的危险性都未飙升。这些女同性恋哮喘的危险性并不优于自然环境绝经的女同性恋，该新研究成果说道。

匹兹堡所学校首席小说道家Karen A. Matthews及上司在一份报告当中写下了他们的找到，这份报告计划于本周在线发布于《美国政府脑癌协会杂志》。

Matthews，匹兹堡的一位优秀的精神病学教授和流行病学与心理学教授，在一份新闻公报当中公开信，这些结果对正试图回避腹腔抽脂的当同龄女同性恋来说道应该是毫无疑问的：

“研究成果结果指出，一般来说自然环境绝经后，腹腔抽脂后的哮喘危险性系数高度不大也许飙升，”Matthews说道。

腹腔抽脂与哮喘危险性

腹腔抽脂是一种故罕见的替换成女同性恋腹腔的外科手术操作。有时，医护人员还替换成腹腔，以增高丙型肝炎危险性。

有时也许明显需要同步进行该操作，比如因为胃癌、腹腔屈曲、织物样肌瘤，或因为非故常较重的更年期过多与痛经，但与此同时，和所有外科手术一样，仍要优劣其收益与危险性。

因为荷尔蒙改变，在绝经同一时间同步进行腹腔抽脂故常引致来得年期提同一时间。

一些更早研究成果指出腹腔抽脂提高肾脏疾病的长期危险性，而肾脏疾病是女同性恋头号杀手。而且他们推论，如果同时摘除腹腔，该危险性将来得高。

但是该观点有缺陷，主要因为这些研究成果倾向于统计分析报告腹腔抽脂与/或腹腔抽脂多年之后的哮喘危险性，而无法将她们在外科手术之同一时间就也许有的危险性回避回头。

研究成果者们做了什么

而在该项新研究成果当中，Matthews及其上司随访了3,302位美国政府绝经同一时间女同性恋11年。这些女同性恋参加了全国女同性恋研究成果（SWAN）。

研究成果伊始，当这些女同性恋加入到SWAN时，她们42-52岁，腹腔明晰，有至少1个腹腔，且无法用到激素疗法。

在随访过后，每年给她们做统计分析报告。在此过后，大部分女同性恋达到自然环境绝经年龄，一些同步进行了腹腔抽脂喜腹腔抽脂，而一些则不喜腹腔抽脂。

同步进行腹腔抽脂的主要因素是织物样肌瘤、更年期过多和慢性肋骨痛。

研究成果者在腹腔抽脂同一时间后统计分析报告了发起者的哮喘危险性，并将这些数据与那些自然环境绝经的女同性恋最后一次更年期同一时间后的危险性相比。

Matthews及其上司说道，他们的研究成果是不单是多民族语言研究成果，了同步进行腹腔抽脂与自然环境绝经的女同性恋的哮喘危险性系数的每年期望改变。

找到了什么

该统计分析辨识腹腔抽脂同一时间后与自然环境绝经同一时间后肾脏危险性系数发生转变，在不同母体，腹腔抽脂者与自然环境绝经者转变Mode大不相同；同时，总体转变Mode辨识腹腔抽脂者肾脏危险性都未飙升，研究成果者们说道。并且，此情形在所有种族组都一样。

并且，即使在更改也许的影响系数——比如人体总质量基准（BMI）——之后，情形仍一样。腹腔抽脂喜腹腔抽脂后，BMI无论如何大大飙升。

因素是什么

Mathews说道他们并不确定为什么他们的找到与辨识腹腔抽脂增高哮喘危险性的更早研究成果不同。

一个因素也许是，他们无法将年轻女同性恋纳入研究成果，而来得早同步进行腹腔抽脂引致的哮喘危险性来得高。

另一个因素，Matthews说道，也许是因为该研究成果排除了因为胃癌而同步进行腹腔抽脂的女同性恋。

SWAN由国家所老年医学研究成果所、国立看护研究成果所、国立卫生研究成果院、女同性恋有益研究成果室和补充与替代医学当中心共同发起。

2011年，《内自然科学解密》杂志所写，来自旧金山纽约所学校的研究成果者们华盛顿邮报，他们找到同步进行了腹腔抽脂喜腹腔抽脂的女同性恋发生丙型肝炎的危险性增高，并且发生其它型式胃癌、脑癌或髋骨折的危险性都未增高。

与腹腔摘除关的的扩充读者：

当中文翻译读者：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."
