Background: Postpartum hypertension is a risk factor for severe maternal morbidity; however, barriers exist for diagnosis and treatment. Remote blood pressure (BP) monitoring programs are an effective tool for monitoring BP and may mitigate maternal health disparities. We aimed to describe and evaluate engagement in a remote BP monitoring program on BP ascertainment during the first 6-weeks postpartum among a diverse patient population.

Background: Extracellular microRNAs (miRNAs) are a class of noncoding RNAs that remain stable in the extracellular milieu, where they contribute to various physiological and pathological processes by facilitating intercellular signaling. Previous studies have reported associations between miRNAs and cardiovascular diseases (CVDs); however, the plasma miRNA signatures of CVD and its risk factors have not been fully elucidated at the population level.

Methods And Results: Plasma miRNA levels were measured in 4440 FHS (Framingham Heart Study) participants.

Article Synopsis
  • Life's Essential 8 (LE8) is a metric designed to assess cardiovascular health, and researchers explored its connections to aging biomarkers and disease risks among 5,682 participants from the Framingham Heart Study.
  • A 1 standard deviation increase in the LE8 score was linked to significant reductions in the risk of cardiovascular disease (CVD), CVD-specific mortality, and overall mortality, with epigenetic age biomarkers playing an important mediating role.
  • The mediation effects were especially pronounced in individuals with a higher genetic risk for older epigenetic age, highlighting the interaction between LE8, genetics, and health outcomes.

Background: The extent to which sex, racial, and ethnic groups receive advanced heart therapies equitably is unclear. We estimated the population rate of left ventricular assist device (LVAD) and heart transplant (HT) use among (non-Hispanic) White, Hispanic, and (non-Hispanic) Black men and women who have heart failure with reduced ejection fraction (HFrEF).

Methods And Results: We used a retrospective cohort design combining counts of LVAD and HT procedures from 19 state inpatient discharge databases from 2010 to 2018 with counts of adults with HFrEF.

Article Synopsis
  • The REDUCE-IT USA trial found that icosapent ethyl (IPE) significantly reduced cardiovascular events by 31% and 36% over approximately 4.9 years.
  • An analysis of the cost-effectiveness of IPE compared to standard care (SC) showed that IPE was less expensive and provided better health outcomes, particularly at a daily cost of $4.59.
  • Overall, IPE is recommended for U.S. patients similar to those in the trial, as it remains cost-effective even at a higher daily cost of $11.48.

Background: The association of the American Heart Association's updated cardiovascular health score, the Life's Essential 8 (LE8), with cardiovascular disease (CVD) and death is not described in the FHS (Framingham Heart Study).

Methods And Results: We evaluated Framingham Offspring participants at examinations 2 and 6 (n=2888 and 1667; and mean age, 44 and 57 years, respectively), free of CVD with information on LE8 components. Using age-sex-adjusted Cox models, we related LE8 and its change (examination 2 to examination 6) with CVD and death risk and compared associations with those of the Life's Simple 7 score.

Article Synopsis
  • This study explores the relationship between exercise impairments and biomarkers in heart failure with preserved ejection fraction (HFpEF), focusing on exercise rather than just resting states.
  • A detailed analysis of 277 proteins was conducted on 151 individuals, identifying specific protein signatures linked to different exercise responses, which helps reveal underlying mechanisms of HFpEF.
  • The findings suggest that these protein signatures not only highlight potential new therapeutic targets but also offer methods for early risk assessment and prevention of HFpEF.

Background During exercise, a healthy arterial system facilitates increased blood flow and distributes it effectively to essential organs. Accordingly, we sought to understand how arterial stiffening might impair cardiorespiratory fitness in community-dwelling individuals. Methods and Results Arterial tonometry and maximum effort cardiopulmonary exercise testing were performed on Framingham Heart Study participants (N=2898, age 54±9 years, 53% women, body mass index 28.

Article Synopsis
  • * Findings validate previous associations, revealing that lower mtDNA CN correlates with a higher risk of coronary heart disease but within the context of no causal relationship established in either direction.
  • * Strong evidence suggests that high low-density lipoprotein cholesterol influences mtDNA CN levels, indicating it may play a key role in the relationship between mtDNA CN and cardiovascular health.

Background A higher burden of cardiovascular disease risk factors has been reported in sexual minority populations. Primordial prevention may therefore be a relevant preventative strategy. The study's objectives are to estimate the associations of Life's Essential 8 (LE8) and Life's Simple 7 (LS7) cardiovascular health scores with sexual minority status.

Heparan sulfate (HS) glycosaminoglycans are widely expressed on the mammalian cell surfaces and extracellular matrices and play important roles in a variety of cell functions. Studies on the structure-activity relationships of HS have long been hampered by the challenges in obtaining chemically defined HS structures with unique sulfation patterns. Here, we report a new approach to HS glycomimetics based on iterative assembly of clickable disaccharide building blocks that mimic the disaccharide repeating units of native HS.

Background Premature onset of cardiovascular disease (CVD) imposes a significant societal burden and challenges prevention efforts. Methods and Results Trends in the incidence of premature CVD (before age 55, 60, or 65 years, separate analysis for each threshold) were evaluated in 14 464 Framingham Heart Study participants over 7 decades of observation (1950-2019). The change in the incidence of premature CVD (per decade) in men and women was assessed using overdispersed Poisson regression (accounting for cohort effects), adjusting for age at entry and age at onset of premature CVD within each decade.
