AHJ：子宮輸精管并不增加心臟病風險

與一些更年前科學研究比如感嘆，一項一新的英國科學研究發現年過男士開展輸卵管切掉（；還有或不；還有輸卵管切掉）后，慢性病的危險性不曾升高。這些男士之前國醫學科學院的危險性并不高于人為絕經的男士，該一新科學研究感嘆。

芝加哥該大學首席著名作家Karen A. Matthews及同僚在一份分析報告之前寫出了他們的發現，這份分析報告計劃于本周在線發布于《英國心臟病發學會雜志》。

Matthews，芝加哥的一位楷模的精神病學任教和醫學研究與社會心理學任教，在一份一新聞公報之前聲明，這些結果對年前就考慮輸卵管切掉的年過男士來感嘆某種程度是無疑的：

“科學研究結果感嘆明了，值得注意人為絕經后，輸卵管切掉后的之前國醫學科學院危險性生物體水平不大或許升高，”Matthews感嘆。

輸卵管切掉與之前國醫學科學院危險性

輸卵管切掉是一種常見的移去男士輸卵管的治療轉換。有時，病人還移去輸卵管，以減小輸卵管癌危險性。

有時或許值得注意需開展該轉換，比如因為癌癥、輸卵管肥大、外皮樣肌瘤，或因為極為重為的月經過多與心痛經，但與此同時，和所有治療一樣，仍要為重其利潤與危險性。

因為荷爾蒙偏離，在絕經在此之前開展輸卵管切掉常導致愈來愈年期提在此之前。

一些更年前科學研究感嘆明了輸卵管切掉進一步提高慢性病的近十年危險性，而慢性病是男士頭號殺手。而且他們推斷，如果同時切掉輸卵管，該危險性將愈來愈高。

但是該見解有缺陷，主要因為這些科學研究極端于審核輸卵管切掉與/或輸卵管切掉多年后來的之前國醫學科學院危險性，而從未將她們在治療之在此之前就或許有的危險性考慮進去。

科學科學家們想到了什么

而在該項一新科學研究之前，Matthews及其同僚隨訪了3,302位英國絕經在此之前男士11年。這些男士參予了全國男士科學研究（SWAN）。

科學研究伊始，當這些男士加入到SWAN時，她們42-52歲，輸卵管完整，有僅僅1個輸卵管，且從未使用激素治療法。

在隨訪期間，每年給她們想到審核。在此期間，大部分男士達到人為絕經年齡，一些開展了輸卵管切掉；還有輸卵管切掉，而一些則不；還有輸卵管切掉。

開展輸卵管切掉的主要理由是外皮樣肌瘤、月經過多和慢性骨盆心痛。

科學科學家在輸卵管切掉在此之前后審核了參與者的之前國醫學科學院危險性，并將這些數據與那些人為絕經的男士最后一次月經在此之前后的危險性相比較。

Matthews及其同僚感嘆，他們的科學研究是首項多民族科學研究，了開展輸卵管切掉與人為絕經的男士的之前國醫學科學院危險性生物體的每年考慮到偏離。

發現了什么

該研究結果顯示輸卵管切掉在此之前后與人為絕經在此之前后心肌梗死危險性生物體引發變動，在多種不同個體，輸卵管切掉者與人為絕經者變動方式在大不相同；同時，總體變動方式在結果顯示輸卵管切掉者心肌梗死危險性不曾升高，科學科學家們感嘆。并且，此情形在所有種族組都一樣。

并且，即使在縮減或許的影響生物體——比如藥劑質量指數（BMI）——后來，情形仍一樣。輸卵管切掉；還有輸卵管切掉后，BMI確實有所升高。

理由是什么

Mathews感嘆他們并不確定為什么他們的發現與結果顯示輸卵管切掉升高之前國醫學科學院危險性的更年前科學研究多種不同。

一個理由或許是，他們從未將年輕男士納入科學研究，而愈來愈年前開展輸卵管切掉導致的之前國醫學科學院危險性愈來愈高。

另一個理由，Matthews感嘆，或許是因為該科學研究排除了因為癌癥而開展輸卵管切掉的男士。

SWAN由國家所老年醫學科學研究所、國立護理科學研究所、國立衛生科學研究部、男士心理健康科學研究中心和補充與替代醫學之前心共同籌劃。

2011年，《內科學檔案》雜志談到，來自舊金山紐約該大學的科學科學家們報道，他們發現開展了輸卵管切掉；還有輸卵管切掉的男士引發輸卵管癌的危險性減小，并且引發其它類型癌癥、心臟病發或髖骨折的危險性不曾升高。

與輸卵管切掉關的的拓展寫作：

出處寫作：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."
