AHJ：子宫切除术并不增加心脏病不确定性

与一些更为早研究成果相反，一项属于自己旧金山研究成果发现中年异性恋开展输卵管矫正（相伴或不相伴生殖细胞开刀）后，心血管疾病的后果并未下跌。这些异性恋妇科的后果这不高于自然环境绝经的异性恋，该新研究成果说道。

西雅图大学高级顾问作家Karen A. Matthews及合作者在一份调查报告中所作了他们的发现，这份调查报告开发计划于本周在线面世于《旧金山肺癌学会杂志》。

Matthews，西雅图的一位杰出的精神障碍客座教授和毒理学与社会心理学客座教授，在一份新闻公报中声明，这些结果对正在考虑输卵管矫正的中年异性恋来说道应该是鼓舞人心的：

“研究成果结果表明，相对于自然环境绝经后，输卵管矫正后的妇科后果q水平不大显然下跌，”Matthews说道。

输卵管矫正与妇科后果

输卵管矫正是一种罕见的移除异性恋输卵管的开刀操纵。有时，病人还移除生殖细胞，以降低生殖细胞癌后果。

有时显然明显需要开展该操纵，比如因为癌症、输卵管下垂、织物都为肌瘤，或因为非经常重的受孕过多与痛经，但与此同时，和所有开刀一都为，仍要权衡其收益与后果。

因为荷尔蒙相反，在绝经前开展输卵管矫正经常导致更为年期提早。

一些更为早研究成果表明输卵管矫正降低心血管疾病的长期后果，而心血管疾病是异性恋头号杀手。而且他们推断，如果同时开刀生殖细胞，该后果将极低。

但是该见解缺失，主要因为这些研究成果倾向于审计输卵管矫正与/或生殖细胞矫正多年最后的妇科后果，而没有将她们在开刀之前就显然有的后果考虑进去。

研究成果者们做了什么

而在该项新研究成果中，Matthews及其合作者随访了3,302位旧金山绝经前异性恋11年。这些异性恋直接参与了全国异性恋研究成果（SWAN）。

研究成果先于，当这些异性恋加入到SWAN时，她们42-52岁，输卵管明晰，有至少1个生殖细胞，且没有经常用激素疗法。

在随访期间，每年给她们做审计。其间，大部份异性恋达到自然环境绝经年岁，一些开展了输卵管矫正相伴生殖细胞矫正，而一些则不相伴生殖细胞矫正。

开展输卵管矫正的主要或许是织物都为肌瘤、受孕过多和慢性骨盆痛。

研究成果者在输卵管矫正前后审计了参与者的妇科后果，并将这些数据与那些自然环境绝经的异性恋终于一次受孕前后的后果相对来说道。

Matthews及其合作者说道，他们的研究成果是时是多汉族的研究成果，了开展输卵管矫正与自然环境绝经的异性恋的妇科后果q的每年短期内相反。

发现了什么

该分析显示输卵管矫正前后与自然环境绝经前后心血管后果q起因起因变化，在不同性状，输卵管矫正者与自然环境绝经者起因变化模式大不相同；同时，总体起因变化模式显示输卵管矫正者心血管后果并未下跌，研究成果者们说道。并且，此情况在所有种族主义组都一都为。

并且，即使在调整显然的影响q——比如人体质量指数（BMI）——最后，情况仍一都为。输卵管矫正相伴生殖细胞矫正后，BMI确实略有下跌。

或许是什么

Mathews说道他们这不确定为什么他们的发现与显示输卵管矫正升高妇科后果的更为早研究成果不同。

一个或许显然是，他们没有将年轻异性恋纳入研究成果，而更为早开展输卵管矫正导致的妇科后果极低。

另一个或许，Matthews说道，显然是因为该研究成果排除了因为癌症而开展输卵管矫正的异性恋。

SWAN由东欧国家老年医学研究成果所、国立护理研究成果所、国立卫生保健研究成果院、异性恋健康研究成果室和必需与替代所学院主导发起。

2011年，《内医学档案》杂志说，来自旧金山加利福尼亚大学的研究成果者们报道，他们发现开展了输卵管矫正相伴生殖细胞矫正的异性恋起因生殖细胞癌的后果降低，并且起因其它种类癌症、肺癌或髋骨腰的后果并未升高。

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."
