Background: Cardiovascular health may be used for prevention of cerebral vascular disease; however, data on the association of cardiovascular health across midlife and late-life with late-life cerebral vascular disease are lacking. Our aim was to examine whether midlife or late-life cardiovascular health as well as changes of cardiovascular health within midlife and between midlife and late-life were associated with prevalence of magnetic resonance imaging markers of cerebral vascular disease at late-life.

Methods: Prospective cohort study including 1638 participants from the Atherosclerosis Risk in Communities Study who took part in 2 visits at midlife (mean ages, 53 and 59 years), and a late-life visit (mean age, 76 years).

Background: To examine the association of ultrasensitive cTnI (cardiac troponin I) with incident cardiovascular disease events (CVDs) in the primary prevention setting.

Methods: cTnI was analyzed in the baseline plasma (2008-2012) of CVD-free volunteers from the Paris Prospective Study III using a novel ultrasensitive immunoassay (Simoa Troponin-I 2.0 Kit, Quanterix, Lexington) with a limit of detection of 0.

Background: Venous thromboembolism (VTE) is a life-threatening vascular event with environmental and genetic determinants. Recent VTE genome-wide association studies (GWAS) meta-analyses involved nearly 30 000 VTE cases and identified up to 40 genetic loci associated with VTE risk, including loci not previously suspected to play a role in hemostasis. The aim of our research was to expand discovery of new genetic loci associated with VTE by using cross-ancestry genomic resources.

Article Synopsis
  • - Pulse wave velocity can indicate early vascular aging and help identify individuals with "supernormal" vascular aging, defined by a significant difference between chronological and vascular age (Δ-age).
  • - In a study of 2,642 individuals over a 6.6-year follow-up, those with supernormal vascular aging had a lower risk of cardiovascular events, while early vascular aging was linked to a higher risk.
  • - This research validates the supernormal vascular aging concept and suggests that understanding it could lead to new protective strategies for healthy vascular aging.

Article Synopsis
  • The study focuses on cardiac allograft vasculopathy (CAV), a significant cause of mortality in heart transplant patients, aiming to identify different progression patterns of CAV and the factors influencing these trajectories.
  • Researchers monitored 1,301 heart transplant recipients from multiple academic centers, analyzing numerous angiographies and medical parameters to forecast CAV development and its association with patient mortality.
  • Four distinct CAV progression profiles were discovered: no CAV progression, late-onset slow progression, mild progression, and accelerated progression, with specific early predictors identified that could help in understanding and managing CAV in patients.

Objective: Impaired baroreflex function is an early indicator of cardiovascular autonomic imbalance. Patients with type 2 diabetes mellitus (T2D) have decreased baroreflex sensitivity (BRS), however, whether the neural BRS (nBRS) and mechanical component of the BRS is altered in those with high metabolic risk (HMR, impaired fasting glucose and metabolic syndrome) or with overt T2D, is unknown. We examined this in a community-based observational study, the Paris Prospective Study III (PPS3).

Physical activity (PA) is a preventative behavior for noncommunicable disease. However, little consideration is given as to whether different domains of PA have differing associations with health outcomes. We sought to determine the association between occupational, sport, leisure, and total PA with baroreflex sensitivity (BRS), distinguishing between neural (nBRS) and mechanical (mBRS) BRS.

Background: Mortality of ST-segment-elevation myocardial infarction (STEMI) decreased drastically, mainly through reduction in inhospital mortality. Prehospital sudden cardiac arrest (SCA) became one of the most feared complications. We assessed the incidence, outcome, and prognosis' predictors of prehospital SCA occurring after emergency medical services (EMS) arrival.

Vascular aging is a major contributor to cardiovascular disease and can be quantified by higher carotid stiffness, intima-media thickness and diameter, and hypertension. Weight gain across the lifetime may be an important, modifiable determinant of vascular aging. We therefore aimed to assess lifetime body silhouette trajectories (a marker of weight change across the lifespan) in relation to vascular aging in late adulthood.

Systemic hypertension is a rapidly growing epidemic in Africa. The role of socioeconomic status on blood pressure control has not been well studied in this part of the world. We, therefore, aimed to quantify the association of socioeconomic status both at the individual and at the country level with blood pressure control in Sub-Saharan Africa.

Article Synopsis
  • Antibody-mediated rejection (AMR) is a significant factor in heart transplant failure, but understanding its mechanisms and improving detection methods is crucial for better outcomes.
  • A study involving 617 heart transplant recipients examined AMR through various techniques, including histopathology, immunostaining, and gene expression profiling, comparing patients with and without AMR.
  • Results indicated that AMR is characterized by specific immune responses and changes in gene expression related to endothelial activation and inflammation, with distinct gene sets that could effectively differentiate between AMR and non-AMR patients.

Background: In-hospital mortality of ST-segment-elevation myocardial infarction (STEMI) has decreased drastically. In contrast, prehospital mortality from sudden cardiac arrest (SCA) remains high and difficult to reduce. Identification of the patients with STEMI at higher risk for prehospital SCA could facilitate rapid triage and intervention in the field.

Objective: We hypothesized that subclinical markers of vascular structure and function, which are independent predictors of cardiovascular disease, would be less frequent in subjects with ideal than poor cardiovascular health (CVH) as defined by the American Heart Association (AHA).

Approach And Results: Carotid parameters were measured using high-precision echotracking device in 9155 nonreferred participants attending a health checkup in a large health center in Paris (France) between 2008 and 2012. According to the AHA, participants with 0 to 2, 3 to 4, and 5 to 7 metrics (smoking, physical activity, body mass index, diet, blood glucose and total cholesterol, blood pressure) at the ideal level were categorized as having poor, intermediate, and ideal CVH.

Background: Whether to perform or not an immediate percutaneous coronary intervention (PCI) after out-of-hospital cardiac arrest is still debated. We aimed to evaluate the impact of PCI on short- and long-term survival in out-of-hospital cardiac arrest patients admitted after successful resuscitation.

Methods And Results: Between 2000 and 2013, all nontrauma out-of-hospital cardiac arrest patients admitted in a Parisian cardiac arrest center after return of spontaneous circulation were prospectively included.
