Background: Glomerular filtration rate (eGFR) derived from serum creatinine (eGFR), cystatin C (eGFR), or both (eGFR) by race-free equations are recommended staging chronic kidney disease (CKD). The current study aimed to compare these race-free eGFR equations for screening for low-grade CKD in Blacks and non-Blacks and to evaluate their association with mortality.

Methods: Race-free eGFR equations were evaluated in four studies with specific inclusion criteria based on the original research goals: African-PREDICT (341/380 healthy Black/White South Africans), FLEMENGHO (709 White community-dwelling Flemish), NHANES (1760/7931 Black and non-Black adult Americans), and 401 Black African patients hospitalised in Mbuji Mayi, Democratic Republic of Congo.

Background And Aims: Hypertension is the predominant modifiable cardiovascular risk factor. This cohort study assessed the association of risk with the percentage of time that the ambulatory blood pressure (ABP) is within the target range (PTTR) proposed by the 2024 European Society of Cardiology (ESC) guidelines for blood pressure (BP) management.

Methods: In a person-level meta-analysis of 14 230 individuals enrolled in 14 population cohorts, systolic and diastolic ABPs were combined to assess 24-h, daytime, and nighttime PTTR with thresholds for non-elevated ABP set at <115/65, <120/70, and <110/60 mmHg, respectively.

Blacks are more prone to salt-sensitive hypertension than Whites. This cross-sectional analysis of a multi-ethnic cohort aimed to search for proteins potentially involved in the susceptibility to salt sensitivity, hypertension, and hypertension-related complications. The study included individuals enrolled in African Prospective Study on the Early Detection and Identification of Cardiovascular Disease and Hypertension (African-PREDICT), Flemish Study of the Environment, Genes and Health Outcomes (FLEMENGHO), Prospective Cohort Study in Patients with Type 2 Diabetes Mellitus for Validation of Biomarkers (PROVALID)-Austria, and Urinary Proteomics Combined with Home Blood Pressure Telemonitoring for Health Care Reform Trial (UPRIGHT-HTM).

Article Synopsis
  • The study investigated the effects of spironolactone on blood pressure (BP) during exercise in heart failure (HF) patients, finding that it significantly reduced both pre- and post-exercise BP levels over 9 months.
  • While spironolactone showed a small improvement in the number of completed shuttles during exercise tests, there was no significant difference in overall exercise capacity or quality of life (QoL) between the spironolactone group and the control group.
  • The results suggest that while spironolactone can lower BP in patients at increased risk of HF, it does not enhance their ability to exercise or improve their overall well-being.

Aims: Few randomized trials assessed the changes over time in the chronotropic heart rate (HR) reactivity (CHR), HR recovery (HRR) and exercise endurance (EE) in response to the incremental shuttle walk test (ISWT). We addressed this issue by analysing the open HOMAGE (Heart OMics in Aging) trial.

Methods: In HOMAGE, 527 patients prone to heart failure were randomized to usual treatment with or without spironolactone (25-50 mg/day).

Screening for and prevention of osteoporosis and osteoporotic fractures is imperative, given the high burden on individuals and society. This study constructed and validated an aging-related biomarker derived from the urinary proteomic profile (UPP) indicative of osteoporosis (UPPost-age). In a prospective population study done in northern Belgium (1985-2019), participants were invited for a follow-up examination in 2005-2010 and participants in the 2005-2010 examination again invited in 2009-2013.

Background: Masked hypertension is associated with target organ damage (TOD) and adverse health outcomes, but whether antihypertensive treatment improves TOD in patients with masked hypertension is unproven.

Methods: In this multicentre, randomised, double-blind, placebo-controlled trial at 15 Chinese hospitals, untreated outpatients aged 30-70 years with an office blood pressure (BP) of <140/<90 mm Hg and 24-h, daytime or nighttime ambulatory BP of ≥130/≥80, ≥135/≥85, or ≥120/≥70 mm Hg were enrolled. Patients had ≥1 sign of TOD: electrocardiographic left ventricular hypertrophy (LVH), brachial-ankle pulse wave velocity (baPWV) ≥1400 cm/s, or urinary albumin-to-creatinine ratio (ACR) ≥3.

Pulse pressure amplification (PPA) is the brachial-to-aortic pulse pressure ratio and decreases with age and cardiovascular risk factors. This individual-participant meta-analysis of population studies aimed to define an outcome-driven threshold for PPA. Incidence rates and standardized multivariable-adjusted hazard ratios (HRs) of cardiovascular and coronary endpoints associated with PPA, as assessed by the SphygmoCor software, were evaluated in the International Database of Central Arterial Properties for Risk Stratification (n = 5608).

Article Synopsis
  • The study analyzed data from the National Health and Nutrition Examination Survey (1999-2020) to evaluate trends in blood lead levels, their association with blood pressure, and mortality rates in the US.
  • Blood lead levels decreased significantly during this period, with a rise in the percentage of people having low lead levels; however, total mortality was not linked to blood lead levels.
  • The research concluded that stricter environmental policies have reduced lead exposure's impact on overall mortality, but there is still a slight association with cardiovascular deaths, which is not linked through blood pressure.

Article Synopsis
  • - This study aimed to define a specific pulse wave velocity (PWV) threshold that can reliably predict cardiovascular events (CVE) and total mortality (TM) using two separate population studies (IDCARS and MONICA) for validation.
  • - Researchers established the risk-carrying PWV threshold at approximately 9 m/s (adjusted to 10 m/s by considering anatomical factors) and found it to predict CVEs and TMs with a hazard ratio indicating increased risk in both study populations.
  • - The findings suggest that PWV can replace multiple traditional risk factors in assessing cardiovascular health and that surpassing the established threshold should prompt healthcare providers to better manage risk factors, especially hypertension.
