According to the CDC (2017), more women than men have died from heart disease over the last 20-25 years. On the contrary, premenopausal women are protected against heart and cardiovascular disease (CVD) compared to men. Following menopause, there is sharp rise in CVD mortality and morbidity in women compared to men indicating that women lose protection against CVD during menopause. This loss of CVD protection in women drives the CDC statistics. Life expectance of women has now reached 82 (almost 35 years longer than at the turn of the 20 century). Yet, women typically undergo menopause at 50-60 years of age, which means that women spend over 40% of their life in menopause. Therefore, menopausal women, and associated CVD risk, must be considered as distinct from an aging or senescent woman. Despite longstanding knowledge that premenopausal women are protected from CVD, our fundamental understanding regarding the shift in CVD risk with menopause remains inadequate and impedes our ability to develop sex-specific therapeutic strategies to combat menopausal susceptibility to CVD. This review provides a critical overview of clinical trials attempting to address CVD susceptibility postmenopausal using hormone replacement therapy. Next, we outline key deficiencies in pre-clinical menopause models and introduce an alternative to overcome these deficiencies. Finally, we discuss a novel connection between AMPK and estrogen-dependent pathways that may serve as a potential solution to increased CVD susceptibility in menopausal women.
根据美国疾病控制与预防中心(2017年)的数据,在过去20至25年中,死于心脏病的女性比男性更多。相反,与男性相比,绝经前女性对心脏和心血管疾病(CVD)具有一定的抵抗力。绝经后,与男性相比,女性心血管疾病的死亡率和发病率急剧上升,这表明女性在绝经期间失去了对心血管疾病的抵抗力。女性对心血管疾病抵抗力的丧失导致了美国疾病控制与预防中心的统计数据。现在女性的预期寿命已达到82岁(比20世纪初延长了近35年)。然而,女性通常在50至60岁时经历绝经,这意味着女性生命中超过40%的时间处于绝经状态。因此,必须将绝经后女性及其相关的心血管疾病风险与老年女性区分开来。尽管长期以来人们都知道绝经前女性对心血管疾病具有抵抗力,但我们对绝经后心血管疾病风险变化的基本认识仍然不足,这阻碍了我们制定针对性别的治疗策略来应对绝经后女性对心血管疾病的易感性。本综述对试图通过激素替代疗法解决绝经后心血管疾病易感性的临床试验进行了批判性概述。接下来,我们概述了临床前绝经模型中的关键缺陷,并介绍了一种克服这些缺陷的替代方法。最后,我们讨论了AMPK与雌激素依赖性途径之间的一种新联系,这可能是解决绝经后女性心血管疾病易感性增加问题的潜在方法。
