AHJ：子宫输精管并不增加心脏病风险

与一些更年前科学研究比如感叹，一项一新的英国科学研究发现年过男士开展输卵管切掉（；还有或不；还有输卵管切掉）后，慢性病的危险性不曾升高。这些男士之前国医学科学院的危险性并不高于人为绝经的男士，该一新科学研究感叹。

芝加哥该大学首席著名作家Karen A. Matthews及同僚在一份分析报告之前写出了他们的发现，这份分析报告计划于本周在线发布于《英国心脏病发学会杂志》。

Matthews，芝加哥的一位楷模的精神病学任教和医学研究与社会心理学任教，在一份一新闻公报之前声明，这些结果对年前就考虑输卵管切掉的年过男士来感叹某种程度是无疑的：

“科学研究结果感叹明了，值得注意人为绝经后，输卵管切掉后的之前国医学科学院危险性生物体水平不大或许升高，”Matthews感叹。

输卵管切掉与之前国医学科学院危险性

输卵管切掉是一种常见的移去男士输卵管的治疗转换。有时，病人还移去输卵管，以减小输卵管癌危险性。

有时或许值得注意需开展该转换，比如因为癌症、输卵管肥大、外皮样肌瘤，或因为极为重为的月经过多与心痛经，但与此同时，和所有治疗一样，仍要为重其利润与危险性。

因为荷尔蒙偏离，在绝经在此之前开展输卵管切掉常导致愈来愈年期提在此之前。

一些更年前科学研究感叹明了输卵管切掉进一步提高慢性病的近十年危险性，而慢性病是男士头号杀手。而且他们推断，如果同时切掉输卵管，该危险性将愈来愈高。

但是该见解有缺陷，主要因为这些科学研究极端于审核输卵管切掉与/或输卵管切掉多年后来的之前国医学科学院危险性，而从未将她们在治疗之在此之前就或许有的危险性考虑进去。

科学科学家们想到了什么

而在该项一新科学研究之前，Matthews及其同僚随访了3,302位英国绝经在此之前男士11年。这些男士参予了全国男士科学研究（SWAN）。

科学研究伊始，当这些男士加入到SWAN时，她们42-52岁，输卵管完整，有仅仅1个输卵管，且从未使用激素治疗法。

在随访期间，每年给她们想到审核。在此期间，大部分男士达到人为绝经年龄，一些开展了输卵管切掉；还有输卵管切掉，而一些则不；还有输卵管切掉。

开展输卵管切掉的主要理由是外皮样肌瘤、月经过多和慢性骨盆心痛。

科学科学家在输卵管切掉在此之前后审核了参与者的之前国医学科学院危险性，并将这些数据与那些人为绝经的男士最后一次月经在此之前后的危险性相比较。

Matthews及其同僚感叹，他们的科学研究是首项多民族科学研究，了开展输卵管切掉与人为绝经的男士的之前国医学科学院危险性生物体的每年考虑到偏离。

发现了什么

该研究结果显示输卵管切掉在此之前后与人为绝经在此之前后心肌梗死危险性生物体引发变动，在多种不同个体，输卵管切掉者与人为绝经者变动方式在大不相同；同时，总体变动方式在结果显示输卵管切掉者心肌梗死危险性不曾升高，科学科学家们感叹。并且，此情形在所有种族组都一样。

并且，即使在缩减或许的影响生物体——比如药剂质量指数（BMI）——后来，情形仍一样。输卵管切掉；还有输卵管切掉后，BMI确实有所升高。

理由是什么

Mathews感叹他们并不确定为什么他们的发现与结果显示输卵管切掉升高之前国医学科学院危险性的更年前科学研究多种不同。

一个理由或许是，他们从未将年轻男士纳入科学研究，而愈来愈年前开展输卵管切掉导致的之前国医学科学院危险性愈来愈高。

另一个理由，Matthews感叹，或许是因为该科学研究排除了因为癌症而开展输卵管切掉的男士。

SWAN由国家所老年医学科学研究所、国立护理科学研究所、国立卫生科学研究部、男士心理健康科学研究中心和补充与替代医学之前心共同筹划。

2011年，《内科学档案》杂志谈到，来自旧金山纽约该大学的科学科学家们报道，他们发现开展了输卵管切掉；还有输卵管切掉的男士引发输卵管癌的危险性减小，并且引发其它类型癌症、心脏病发或髋骨折的危险性不曾升高。

与输卵管切掉关的的拓展写作：

出处写作：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."
