AHJ：子宫切除术十分增加心脏病风险

与一些来得更早数据资料分析反之亦然，一项原先的英美两国数据资料分析发掘出之当年年男人完成输卵管抽脂（相伴或不相伴输卵管缝合）后，冠心病疾病的危险性都未升高。这些男人冠心病的危险性不一定高于纯净绝经的男人，该原先数据资料分析知道。

圣路易斯的学校总监诗人Karen A. Matthews及同事在一份报告之当年写下了他们的发掘出，这份报告计划于本周在线发布于《英美两国心脏病学会周报》。

Matthews，圣路易斯的一位卓越的精神病学教授和医学数据资料分析与社会心理学教授，在一份原先闻公报之当年声明，这些结果对正在顾虑输卵管抽脂的之当年年男人来知道应该是鼓舞人心的：

“数据资料分析结果表明，相对纯净绝经后，输卵管抽脂后的冠心病危险性系数高水平不大或许升高，”Matthews知道。

输卵管抽脂与冠心病危险性

输卵管抽脂是一种故相似的移除男人输卵管的切除操作。有时，病人还移除输卵管，以减少输卵管癌危险性。

有时或许显著无需完成该操作，比如因为癌症、输卵管卷曲、橡胶样肌瘤，或因为非故常为重的月经过多与痛经，但与此同时，和所有切除一样，仍要关系到其收益与危险性。

因为荷尔蒙改变，在绝经当年完成输卵管抽脂故常造成来得年期月内。

一些来得更早数据资料分析表明输卵管抽脂提高冠心病疾病的长期危险性，而冠心病疾病是男人头号杰森。而且他们推断，如果同时缝合输卵管，该危险性将来得好。

但是该观点有缺陷，主要因为这些数据资料分析极端于评量输卵管抽脂与/或输卵管抽脂多年之后的冠心病危险性，而没将她们在切除之当年就或许有的危险性顾虑进去。

人类学家们做了什么

而在该项原先数据资料分析之当年，Matthews及其同事随访了3,302位英美两国绝经当年男人11年。这些男人参加了全中国男人数据资料分析（SWAN）。

数据资料分析伊始，当这些男人加入到SWAN时，她们42-52岁，输卵管完整，有至少1个输卵管，且没用作激素疗法。

在随访前夕，每年给她们做评量。从那时起，仅有男人超过纯净绝经成年，一些完成了输卵管抽脂相伴输卵管抽脂，而一些则不相伴输卵管抽脂。

完成输卵管抽脂的主要原因是橡胶样肌瘤、月经过多和慢性骨盆痛。

人类学家在输卵管抽脂当年后评量了参与者的冠心病危险性，并将这些数据资料与那些纯净绝经的男人之当年一次月经当年后的危险性比起。

Matthews及其同事知道，他们的数据资料分析是首项多民族数据资料分析，了完成输卵管抽脂与纯净绝经的男人的冠心病危险性系数的每年在短期内改变。

发掘出了什么

该分析结果显示输卵管抽脂当年后与纯净绝经当年后冠心病危险性系数发生改变，在不同个体，输卵管抽脂者与纯净绝经者改变模式大不相同；同时，总体改变模式结果显示输卵管抽脂者冠心病危险性都未升高，人类学家们知道。并且，此原因在所有族群组都一样。

并且，即使在调整或许的制约系数——比如人体低质量指数（BMI）——之后，原因仍一样。输卵管抽脂相伴输卵管抽脂后，BMI确实不大升高。

原因是什么

Mathews知道他们不一定未确定为什么他们的发掘出与结果显示输卵管抽脂急剧下降冠心病危险性的来得更早数据资料分析不同。

一个原因或许是，他们没将年轻男人纳入数据资料分析，而来得来得早完成输卵管抽脂造成的冠心病危险性来得好。

另一个原因，Matthews知道，或许是因为该数据资料分析剔除了因为癌症而完成输卵管抽脂的男人。

SWAN由国家老年医学数据资料分析院、国立保健数据资料分析院、国立卫生数据资料分析之当年心、男人心理健康数据资料分析室和必要与替代医学之当年心共同发起。

2011年，《内科学档案》周报写道，来自旧金山加利福尼亚的学校的人类学家们华盛顿邮报，他们发掘出完成了输卵管抽脂相伴输卵管抽脂的男人发生输卵管癌的危险性减少，并且发生其它一般来说癌症、心脏病或髋骨折的危险性都未急剧下降。

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."
