Background: Women show a rise in HDL cholesterol efflux capacity (CEC) as they traverse menopause. Whether this rise is associated with a lower risk of cardiovascular disease (CVD) overtime is not clear.

Objectives: We tested whether CEC association with subclinical vascular health, measured using a composite subclinical vascular health score based on levels of carotid-intima media thickness (cIMT), carotid-femoral pulse wave velocity (cfPWV), and presence of coronary artery calcium (CAC score >10), varies by time relative to the final menstrual period (FMP).

Surgical menopause, the removal of both ovaries prior to natural menopause, may impact short-and long-term physical and emotional health. An increasingly common cause of surgical menopause is risk-reducing salpingo-oophorectomy (RRSO) in those at high inherited risk of ovarian cancer. The WHAM (What Happens After Menopause?) study is the largest prospective controlled study of RRSO.

Context: The timing of a woman's final menstrual period (FMP) in relation to her age is considered a valuable indicator of overall health, being associated with cardiovascular, bone health, reproductive, and general mortality outcomes.

Objective: This work aimed to evaluate the relationship between hormones and the "time to FMP" when daily hormone trajectories are characterized by their 1) entropy, and 2) deviation from premenopausal/stable cycle patterns (representing a textbook "gold standard"; GS).

Methods: As part of the Study of Women's Health Across the Nation, urinary luteinizing hormone (LH), follicle-stimulating hormone (FSH), estrogen conjugates (E1C), and pregnanediol glucuronide (PDG) were measured daily from a multiracial sample of 549 mid-life women for the duration of one menstrual cycle.

Article Synopsis
  • The study investigates the role of high-density lipoprotein cholesterol (HDL-C) in midlife women diagnosed with metabolic syndrome (MetS) and its relation to the risk of diabetes and carotid intima-media thickness (cIMT).
  • Researchers categorized participants into three groups: women without MetS, those with MetS and HDL-C levels ≥ 50 mg/dL (MetS hiHDL), and those with HDL-C < 50 mg/dL (MetS loHDL), measuring cIMT 13.8 years later and assessing diabetes risk yearly.
  • Findings indicate that although both MetS groups (hiHDL and loHDL) had higher risks of

Objective: The clinical utility of high-density lipoprotein cholesterol (HDL-C) in risk classification is limited, especially in midlife women. Novel metrics of HDL may better reflect this risk. We clustered a comprehensive profile of HDL metrics into favorable and unfavorable clusters and assessed how these two clusters are related to future subclinical atherosclerosis (carotid intima media thickness [cIMT], interadventitial diameter [IAD], and carotid plaque presence) in midlife women.

Background: Up to 50% of women report sleep problems in midlife, and cardiovascular disease (CVD) is the leading cause of death in women. How chronic poor sleep exposure over decades of midlife is related to CVD risk in women is poorly understood. We tested whether trajectories of insomnia symptoms or sleep duration over midlife were related to subsequent CVD events among SWAN (Study of Women's Health Across the Nation) participants, whose sleep was assessed up to 16 times over 22 years.

Objective: Perimenopausal women experience a steep increase in low-density lipoprotein cholesterol (LDL-C) that is related to a higher risk of carotid plaque later in life. Low-density lipoprotein subclasses have been linked to cardiovascular diseases beyond LDL-C, promising a better risk stratification. We aim to characterize changes in LDL subclasses and assess their associations with presence of coronary artery calcium (CAC score ≥10) and carotid intima-media thickness (cIMT) over the menopausal transition (MT) and by menopause stage.

It is known that the menopause transition (MT) is a complex period during a woman's life, but there has been ongoing debate on whether the increase in cardiovascular disease (CVD) during midlife is due to chronological aging or ovarian aging. The purpose of this review is to summarize the recent findings on the role of ovarian aging versus chronological aging on cardiovascular disease (CVD) outcomes and its risk factors in women. Recent data from longitudinal studies have shown that menopause-related factors, such as earlier age at menopause and surgical menopause are associated with higher CVD outcomes.

The menopause transition is a critical period for cardiovascular health. During this stage, women experience adverse changes in multiple components that are key for optimal cardiovascular health. Additionally, women struggle to maintain ideal health behaviors, which if adopted collectively, have been shown in observational studies to prevent more than 70% of coronary heart disease cases.

In this JCL Roundtable, we bring together three experts to discuss women's cardiovascular health throughout the lifespan, viewed from the standpoint of clinical lipidology. Overall, heart disease leads to one out of every 3 deaths of American women, but unfortunately patient awareness of cardiovascular risk actually has declined since 2009. Younger women are not exempt, since their risk can be increased by smoking, birth control, adverse lifestyle and diet, and genetic disorders.

Background: The menopause transition (MT) is linked to adverse changes in lipids/lipoproteins. However, the related contributions of anti-Müllerian hormone (AMH) and estradiol (E2) are not clear.

Objective: To evaluate the independent associations of premenopausal AMH and E2 levels and their changes with lipids/lipoproteins levels [total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), apolipoprotein B (apoB) and apolipoprotein A-1 (apoA-1)] over the MT.

Background Utility of high-density lipoprotein cholesterol (HDL-C) in assessing the antiatherogenic properties of HDL may be limited in midlife women. Novel metrics of HDL function, lipid contents, and subclasses may better reflect the atheroprotective capacities of HDL, supporting the need to evaluate how cardiovascular health affects these metrics in women. We assessed the relationship of early midlife Life's Simple 7 (LS7) score and its health behavior components with future HDL function (HDL-cholesterol efflux capacity), HDL-phospholipid, HDL-triglyceride, HDL particles (HDL-P) and size, and the relationship between LS7 score and changes in HDL metrics over time.
