摘要
怀孕通常被描述为一种生理上的“压力测试”,可能会发现潜在的风险。
高血压、糖尿病和心血管疾病。即使在不复杂的怀孕中,女性也会经历快速
心脏代谢变化以支持胎儿发育。虽然许多这样的改编
分娩后不久恢复正常,一些变化持续存在,包括超声心动图的变化
心脏结构和较低的高密度脂蛋白胆固醇(HDL-C)。不管是这些
与怀孕有关的变化,或高密度脂蛋白颗粒结构或功能的变化,有助于
长期的心血管风险是未知的。平价,或活产婴儿总数,在后
更年期妇女患心血管疾病的风险也更高
高密度脂蛋白胆固醇水平、高密度脂蛋白结构和功能以及心脏和血管功能的改变。
然而,在将观察到的心血管变化联系起来方面存在着显著的研究差距。
怀孕与观察到的产次与绝经后心血管健康的关系。
我们将通过利用现有数据和来自NHLBI增长的样本来解决这一差距
健康研究(NGHS)并对350名参与者进行了新的面对面访问,年龄中值为46岁,
当女性处于绝经期前或围绝经期时。NGHS招收了871名女孩(50%是非洲人-

英文摘要
Abstract
Pregnancy is often described as a physiologic “stress test” that may uncover latent risk for
hypertension, diabetes and CVD. Even in uncomplicated pregnancies, women experience rapid
cardiometabolic changes to support fetal development. While many of these adaptations
normalize soon after delivery, some changes persist, including echocardiographic changes in
cardiac structure and lower high-density lipoprotein cholesterol (HDL-C). Whether these
pregnancy-related changes, or alterations in HDL particle structure or function, contribute to
long-term cardiovascular risk is unknown. Parity, or the total number of live births, among post-
menopausal women is also associated with greater risk of cardiovascular disease and
alterations in HDL-C levels, HDL structure and function, and cardiac and vascular function.
However, a significant research gap exists in linking observed cardiovascular changes across
pregnancy to the observed associations of parity with cardiovascular health post-menopause.
We will address this gap by leveraging existing data and samples from the NHLBI Growth and
Health Study (NGHS) and conduct a new in-person visit in 350 participants at median age 46,
when the women will be pre- or peri-menopausal. NGHS enrolled 871 girls (50% African-
American and 50% white) in 1987 at age 9 or 10 and examined them up to 17 times, to age 27,
including 7 echocardiograms between ages 20-27, multiple saved samples and reproductive
history questionnaires. This study will conduct detailed lipoprotein sizing and functionality
assessments from stored and new samples and conduct cardiovascular imaging and repeat
echocardiograms at median age 46 to: 1) Determine the specific lipoprotein particle size
distribution and function changes which occur from before to short- and long-term post
pregnancy; 2) Determine whether pregnancy-related cardiac adaptations result in long-term
alterations in cardiac structure and function, thereby increasing CVD risk for women in their
forties; and 3) Test whether parity increases CV risk independently of socioeconomic status
(SES) in African-American and white women. With the completion of our aims, we will have
determined the prospective pathways between pregnancy-related lipoprotein and cardiovascular
changes and pre-menopausal cardiovascular health for women in their forties. Results from our
proposed studies will fill a critical gap in our understanding of how such risks may accumulate
during a woman's reproductive life, as well as how socioeconomic status contributes to parity-
related risk long-term. Women in this study have also been exposed to the obesity epidemic,
lending greater understanding to contemporary reproductive development.
