Article Synopsis
  • - The study focused on how obesity and depressive symptoms are linked to chest pain (CP) in patients with nonobstructive coronary artery disease, revealing that 71.5% of participants experienced CP, with a particularly higher prevalence in those with obesity (77.6% vs. 67%).
  • - Out of 814 patients, obesity was found to significantly increase CP occurrence, especially in men, who showed more frequent and prevalent CP compared to women with similar obesity levels.
  • - The research concluded that both obesity and depressive symptoms are independently associated with CP, and the impact of obesity on CP in men was partially mediated by levels of depressive symptoms.

Article Synopsis
  • The study investigates the relationship between serum calcium levels and ventricular repolarization time, specifically the QT and JT intervals, which are important for heart health.
  • Researchers conducted large-scale genome-wide analyses to explore potential interactions between calcium levels and genetic variants associated with QT and JT intervals, using over 122,000 participants.
  • The results showed limited evidence for the hypothesized calcium interaction effects, suggesting that other factors, such as rare genetic variations or environmental influences, likely play a larger role in the unexplained heritability of QT and JT intervals.

  • Frailty is linked to increased cardiovascular disease (CVD) risk and mortality among US veterans, highlighting the importance of identifying frailty for better health outcomes.
  • In a study of nearly 190,688 veterans aged 50 and older, frailty was assessed using three different scoring systems, revealing a significant correlation between frailty and higher mortality rates from all causes and CVD.
  • The results suggest that regardless of the method used to measure frailty, it consistently indicates a greater risk for negative health events, indicating a need for more research specifically focusing on younger veterans under 60.

Background: African American women bear a disproportionate burden of cardiovascular diseases, potentially due to altered central hemodynamics. Racism and sexism often lead to African American women taking on numerous caretaking roles and overall increases their use of the Strong Black Woman (ie, Superwoman) mindset, which may have negative health consequences. We hypothesized that endorsing the Superwoman role and its Obligation to Help Others dimension would be associated with a deleterious central hemodynamics profile in African American women.

  • Septic shock leads to increased end-diastolic volume (EDV) and decreased ejection fraction in survivors, unlike nonsurvivors, whose EDV does not increase due to more severe diastolic dysfunction early in the condition.* -
  • In a study with beagles, findings indicate that septic animals experienced significant heart issues, including wall edema and thinning, resulting in decreased heart performance, particularly in nonsurvivors during the initial phase of sepsis.* -
  • The research suggests that cardiac dysfunction during sepsis is connected to microvascular injury and edema, with important implications for understanding heart changes and recovery in septic patients.*

Background: Socioeconomic factors may lead to a disproportionate impact on health care usage and death among individuals with congenital heart defects (CHD) by race, ethnicity, and socioeconomic factors. How neighborhood poverty affects racial and ethnic disparities in health care usage and death among individuals with CHD across the life span is not well described.

Methods And Results: Individuals aged 1 to 64 years, with at least 1 CHD-related () code were identified from health care encounters between January 1, 2011, and December 31, 2013, from 4 US sites.

Background: The mortality risk attributable to moderate aortic stenosis (AS) remains incompletely characterized and has historically been underestimated. We aim to evaluate the association between moderate AS and all-cause death, comparing it with no/mild AS (in a general referral population and in patients with heart failure with reduced ejection fraction).

Methods And Results: A systematic review and pooled meta-analysis of Kaplan-Meier-derived reconstructed time-to-event data of studies published by June 2023 was conducted to evaluate survival outcomes among patients with moderate AS in comparison with individuals with no/mild AS.

Shellfish harvesting is central to coastal Alaska Native ways of life, and tribes in Southeast Alaska are committed to preserving sustainable and safe access to subsistence foods. However, consumption of non-commercially harvested shellfish puts Alaska Native communities at elevated risk of exposure to shellfish toxins. To address a lack of state or federal toxin testing for subsistence and recreational harvesting, tribes across Southeast Alaska have formed their own toxin testing and ocean monitoring program.

The protection and management of water resources continues to be challenged by multiple and ongoing factors such as shifts in demographic, social, economic, and public health requirements. Physical limitations placed on access to potable supplies include natural and human-caused factors such as aquifer depletion, aging infrastructure, saltwater intrusion, floods, and drought. These factors, although varying in magnitude, spatial extent, and timing, can exacerbate the potential for contaminants of concern (CECs) to be present in sources of drinking water, infrastructure, premise plumbing and associated tap water.
