今天发表在 Cochrane Library的新证据显示,激素替代疗法并不能保护绝经后妇女免受心血管疾病,甚至可能导致中风的风险增加。

HRT,现在通常被称为激素疗法,被广泛用于控制更年期症状。它也被用于预防绝经后妇女心血管疾病。这一最新迹象查看了使用激素治疗至少6个月的影响,超过40,000名女性参与了这项研究。

这些女性的治疗时间不同,整个试验从7个月到刚刚超过10年。

总的来说,结果表明,没有证据表明激素疗法为任何原因的死亡提供了任何保护作用,特别是心血管疾病引起的死亡,非致命性心脏病发作或心绞痛,无论是在健康女性或预先存在的心脏疾病的妇女。取而代之的结果增加了绝经后女性中风的风险。

作者还探讨早期开始HRT的效果。他们发现一些证据表明,那些在更年期前10年开始治疗的女性中,更年期时最常见的的症状,似乎对防止死亡、心脏发作和中风的风险增加有一些保护。但即使是在该组中,深部静脉血栓形成的风险(DVT)增加了。

这项研究的作者牛津大学心血管医学部亨利•博德曼博士说,激素治疗的益处和坏处是根据女性开始治疗时的年龄变化的。

他说,“我们有证据提供了所谓的‘时机假说’的一些支持,但是我们应该记住这种影响的大小。当我们看着这个结果,根据妇女的年龄,或她们的更年期时开始接受治疗的时间,我们发现,如果60岁以下的1000名女性开始激素治疗,我们期待与没有激素治疗的相比,在大于7年的时候,能够减少6例死亡人数、8例心脏疾病。”

博德曼医生继续说:“这个Cochrane评价的结果需要慎重考虑。这是一个复杂的健康问题,当同一种治疗为一些女性提供一些益处时,但也存在其他的危害。”

Cochrane Library首席编辑David Tovey评论道,“这项综述为使用HRT治疗更年期症状提供了一些证据。作者进行的主要分析发现没有任何益处,所以我们需要更加注意亚组的分析结果。然而这如果是真的,防止年轻女性心脏疾病的明显益处应该与其他可能的益处和伤害一起考虑,包括乳腺癌卵巢癌和深静脉血栓形成的风险。”

该Cochrane Review的作者亨利•博德曼博士总结道,“激素疗法仍然是受更年期困扰的女性的有效的治疗方法,然而这种治疗的风险和好处是根据年龄和病史而有所不同。当考虑治疗时建议与您的家庭医生进行讨论。”

Circulation :低心脏指数与痴呆和阿尔兹海默病风险升高有关

对心脏指数与脑老化之间的了解知之甚少。临床和流行病学数据显示,心血管风险因子,减少的心脏输出量与认知能力减退,脑容量减少,白质高信号以及白质损伤有关。这可能与全身血流量紊乱脑血流量平衡,尤其是在老年患者中。美国田纳西州诺希维尔范德比尔特大学医学中心Angela L. Jefferson博士等人研究了心脏指数与痴呆和阿尔兹海默病之间的关联,成果发表在2月份Circulation期刊上。 背景:
