Background: Allostatic load (AL), a measure of cumulative stress-related physiological dysregulation, predicts the onset of chronic diseases. We investigated the relationship between AL and cardiovascular disease (CVD)-free survival in parents and offspring, including sex-specific differences.

Methods: The analysis consisted of 6145 offspring-mother-father trios derived from the Framingham Heart Study.

During the past 3 decades, life course socio-ecological frameworks have received considerable attention from clinical and public health professionals; developmental, social, and behavioral scientists; and scholars. Substantial evidence underscores the importance of a life course approach to prevention of cardiovascular (CV) disease and the promotion of optimal CV health. This article provides an overview of evidence on early origins and progression of CV disease (CVD) processes across the life course of individuals from diverse populations.

Maternal blood pressure (BP) is a critical cardiovascular marker with profound implications for maternal and fetal well-being, particularly in the detection of hypertensive disorders during pregnancy. Although conventional clinic-based BP (CBP) measurements have traditionvally been used, monitoring 24-hour ambulatory BP (ABP) has emerged as a more reliable method for assessing BP levels and diagnosing conditions such as gestational hypertension and preeclampsia/eclampsia. This study aimed to assess the feasibility and acceptability of 24-hour ABP monitoring in pregnant women and report on various ABP parameters, including ambulatory blood pressure variability (ABPV).

Background: There is evidence that heart failure with preserved ejection fraction (HFpEF)-related hospitalizations are increasing in the United States. However, there is a lack of knowledge about HFpEF-related hospitalizations among younger adults.

Objective: The aims of this study were to perform a retrospective analysis using the Nationwide Inpatient Sample and to examine age-stratified sex differences in the prevalence, correlates, and outcomes of HFpEF-related hospitalization across the adult life span.

Takotsubo cardiomyopathy (TCM) is most common not only in postmenopausal women aged ≥50 yr but also in pregnant individuals. However, there are no national estimates on the prevalence, timing of occurrence, correlates, and outcomes of pregnancy-associated TCM. Using the Nationwide Inpatient Sample (NIS: 2016-2020), we describe rates of pregnancy-associated TCM hospitalizations among 13- to 49-yr-old pregnant individuals in the United States by selected demographic, behavioral, hospital, and clinical characteristics.

Background: Disability-adjusted life years (DALYs) are used to evaluate the relative burden of diseases in populations to help set prevention or treatment priorities. The impact of parental cardiovascular health (CVH) on healthy life years lost from cardiovascular disease (CVD) in adult offspring is unknown. We compared parent-offspring CVD DALYs trends over the life course and examined the association of parental CVH with offspring CVD DALYs.

Background: Cardiovascular (CV) risk factors can be transmitted from mothers to their children. However, it is challenging to measure and identify subclinical CV risk in young children using traditional CV risk methods and metrics.

Objective: The purpose of this study was to determine the feasibility of recruiting mother-child dyads and measuring arterial stiffness (pulse wave velocity, augmentation index/pressure), blood pressure (BP), BP circadian pattern, specifically nocturnal BP dipping, and CV health metrics in mothers and in children aged 1 to 5 years.

Background: Cardiovascular-related adverse childbirth outcomes have been increasing in the United States, with widening racial and ethnic disparities.

Objective: We examined the association between maternal cardiovascular health (CVH) and childbirth outcomes among US births.

Methods: We analyzed data from the Pregnancy Risk Assessment Monitoring System.

Background: Cardiovascular disease (CVD) risk factors are transmitted from parents to children. We prospectively examined the association between parental cardiovascular health (CVH) and time to onset of CVD in the offspring.

Methods And Results: The study consisted of a total of 5967 offspring-mother-father trios derived from the Framingham Heart Study.

Background: Cardiovascular conditions are leading contributors to increasing maternal morbidity and mortality. Heart failure with preserved ejection fraction (HFpEF) results in the majority of HF admissions in women, yet its impact in pregnancy is unknown. We examined the prevalence rates, risk factors and adverse pregnancy outcomes in women with HFpEF during pregnancy-related hospitalizations in the United States.

Background Evidence suggests familial aggregation and intergenerational associations for individual cardiovascular health (CVH) metrics. Over a 53-year life course, we examined trends and association of CVH between parents and their offspring at similar mean ages. Methods and Results We conducted a series of cross-sectional analyses of the FHS (Framingham Heart Study).

Background And Purpose: Diagnostic algorithms are invaluable tools for screening diabetes. This review aimed to evaluate and identify the most robust methodological approaches for developing diagnostic algorithms for screening diabetes.

Methods: Following a literature search, methodological quality of algorithm development studies was evaluated using the TRIPOD guidelines (Collins, Reitsma, Altman, & Moons, 2015).

This essay addresses the name of our discipline. Discussion of the use of the term, nursology, focuses on the origin of the term, its use as a name for our discipline and its use as a research method and a practice methodology. Advantages and disadvantages of nursology as the name for our discipline are gleaned from PhD program students' responses to a question posed by Reed (1997).
