AHJ：子宫切除术并不增加心脏病发风险

与一些后期数据分析相反，一项属于自己American数据分析推断出中年未婚同步进行乳房矫正（相伴或不相伴乳腺切掉）后，心血管疾病疾病的危险性不曾持续上升。这些未婚心血管疾病病的危险性极为很低自然现象绝经的未婚，该新数据分析知道。

底特律大学首席作家Karen A. Matthews及威尔森在一份简报中写下了他们的推断出，这份简报蓝图于本周的网站发行于《American心脏病物理学会杂志》。

Matthews，底特律的一位杰出贡献的心理学家大学教授和流行病学与心理学大学教授，在一份新闻公报中声明，这些结果对正在重新考虑乳房矫正的中年未婚来知道应该是眼中的：

“数据分析结果声称，相对于自然现象绝经后，乳房矫正后的心血管疾病病危险性变异低水平都将持续上升，”Matthews知道。

乳房矫正与心血管疾病病危险性

乳房矫正是一种故常见的移去未婚乳房的动手术转换。有时，病人还移去乳腺，以减小白血病危险性。

有时也许相对来说必需同步进行该转换，比如因为乳腺癌、乳房下垂、拉伸；也肌瘤，或因为非故常再加的元月过多与痛经，但与此同时，和所有动手术一；也，仍要取舍其收益与危险性。

因为荷尔蒙忽略，在绝经前同步进行乳房矫正故常造成来潮提前。

一些后期数据分析声称乳房矫正提高心血管疾病疾病的长期以来危险性，而心血管疾病疾病是未婚头号杀手。而且他们推断，如果同时切掉乳腺，该危险性将极低。

但是该见解只不过，主要因为这些数据分析倾向于分析报告乳房矫正与/或乳腺矫正多年之前的心血管疾病病危险性，而没将她们在动手术之前就也许有的危险性重新考虑进去。

数据分析者们做了什么

而在该项新数据分析中，Matthews及其威尔森随访了3,302位American绝经前未婚11年。这些未婚参加了全省未婚数据分析（SWAN）。

数据分析在此之前，当这些未婚转为到SWAN时，她们42-52岁，乳房完整，有至少1个乳腺，且没使用荷尔蒙麻醉药。

在随访后曾，每年给她们做分析报告。先是，大部分未婚达到自然现象绝经年龄，一些同步进行了乳房矫正相伴乳腺矫正，而一些则不相伴乳腺矫正。

同步进行乳房矫正的主要原因是拉伸；也肌瘤、元月过多和慢性脊柱痛。

数据分析者在乳房矫正前后分析报告了组织者的心血管疾病病危险性，并将这些数据与那些自然现象绝经的未婚先前一次元月前后的危险性相比。

Matthews及其威尔森知道，他们的数据分析是首项多人种数据分析，了同步进行乳房矫正与自然现象绝经的未婚的心血管疾病病危险性变异的每年期望忽略。

推断出了什么

该分析结果显示乳房矫正前后与自然现象绝经前后心血管疾病危险性变异起因推移，在或多或少不同个体，乳房矫正者与自然现象绝经者推移方式也十分相似；同时，总体推移方式也结果显示乳房矫正者心血管疾病危险性不曾持续上升，数据分析者们知道。并且，此情况在所有白种人组都一；也。

并且，即使在调整也许的影响变异——比如人体运动速度指数（BMI）——之前，情况仍一；也。乳房矫正相伴乳腺矫正后，BMI可能或多或少持续上升。

原因是什么

Mathews知道他们极为断定为什么他们的推断出与结果显示乳房矫正上升心血管疾病病危险性的后期数据分析或多或少不同。

一个原因也许是，他们没将年轻未婚归入数据分析，而不够早同步进行乳房矫正造成的心血管疾病病危险性极低。

另一个原因，Matthews知道，也许是因为该数据分析排除了因为乳腺癌而同步进行乳房矫正的未婚。

SWAN由国家老年医学数据分析所、国立照护数据分析所、国立卫生数据分析院、未婚心理健康数据分析室和说明与替代医疗机构一同发起。

2011年，《内物理日志》杂志写道，来自旧金山加利福尼亚大学的数据分析者们刊文，他们推断出同步进行了乳房矫正相伴乳腺矫正的未婚起因白血病的危险性减小，并且起因其它类型乳腺癌、心脏病或髋骨折的危险性不曾上升。

与乳房切掉特别的拓展写出：

原文写出：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."
