Aerobic Exercise Training, Biological Age, and Mortality in Chronic Heart Failure With Reduced Ejection Fraction.

Background: Among individuals with chronic heart failure with reduced ejection fraction (HFrEF), the predictive value for mortality by biomarker-based biological age (BA) and whether aerobic exercise training (AET) modifies the association are understudied.

Objectives: The authors aimed to investigate the association between BA and mortality among individuals with HFrEF and assess whether AET modifies the association.

Methods: Including participants in HF-ACTION (Heart Failure: A Controlled Trial Investigating Outcomes of Exercise Training), BA acceleration was constructed by the Klemera-Doubal method, using the residual of a linear model of BA and chronological age.

Equations for Predicting the 10-Year Risk of Atherosclerotic Cardiovascular Disease in Population With Obesity.

Background: Atherosclerotic cardiovascular disease (ASCVD) is a significant public health issue; however, current risk prediction models have limitations in populations with obesity.

Objectives: The aim of this study was to develop risk models for predicting ASCVD risk in patients with obesity.

Methods: Gender-specific equations to predict ASCVD were developed and validated using a cohort of 3,058 participants with obesity (body mass index ≥30 kg/m) in the ARIC (Atherosclerosis Risk In Communities) study and 1,953 participants in MESA (Multi-Ethnic Study of Atherosclerosis).

Association between triglyceride-glucose-body mass index and risk of aortic stenosis progression in patients with non-severe aortic stenosis: a retrospective cohort study.

Background: Triglyceride-glucose-BMI (TyG-BMI) index is a surrogate marker of insulin resistance and an important predictor of cardiovascular disease. However, the predictive value of TyG-BMI index in the progression of non-severe aortic stenosis (AS) is still unclear.

Methods: The present retrospective observational study was conducted using patient data from Aortic valve diseases RISk facTOr assessmenT andprognosis modeL construction (ARISTOTLE).

Dysfunction in neuro-mesenchymal units impairs the development of bone marrow B cells in mice with anxiety.

The reduction in B lymphocytes observed in individuals with anxiety disorders may compromise antiviral responses, yet the precise mechanisms behind this decline remain unclear. While elevated glucocorticoid levels have been suggested as contributing factors, anxiety disorders are associated with diminished glucocorticoid signaling. Given that autonomic nervous system dysfunction is a hallmark of anxiety disorders, we established an anxiety-related behavior mouse model by stimulating C1 neurons in the rostral ventrolateral medulla.

Prognostic significance of aortic valve calcification in relation to coronary artery calcification for cardiovascular diseases.

Aims: Both coronary artery calcification (CAC) and aortic valve calcification (AVC) are strongly associated with cardiovascular diseases (CVDs), but data about the prognostic significance of multiple cardiovascular calcifications are limited. We aim to investigate the interaction relationship between AVC and CAC for major events.

Methods And Results: We included 6695 participants from the Multi-Ethnic Study of Atherosclerosis at baseline and divided them into four groups: (i) no AVC or CAC; (ii) only AVC; (iii) only CAC; and (iv) with CAC and CAC.

Physical Activity and Weight Loss Among Adults With Type 2 Diabetes and Overweight or Obesity: A Post Hoc Analysis of the Look AHEAD Trial.

Importance: Prior findings from the Look AHEAD trial showed no significant reduction in the risk of cardiovascular events by lifestyle-induced weight loss among individuals with type 2 diabetes (T2D) and overweight or obesity. However, physical activity (PA) may modify the changes in cardiovascular risk associated with weight loss.

Objective: To examine the joint association of weight loss and PA with the risk of adverse cardiovascular events in patients with T2D and overweight or obesity.

Long-term physical activity time-in-target range in young adults with cardiovascular events in later life.

Aims: Achieving at least 150 min per week of moderate-to-vigorous physical activity (PA) is a 'Class I, A level' recommendation for the primary prevention of cardiovascular disease. However, long-term PA is a complex behaviour and varied by lifetime, which was insufficiently reflected by the current studies. This study used time-in-target range (TTR) to measure the long-term PA level during young adulthood and investigated its relationship with cardiovascular events in later life.

Remnant Cholesterol in Young Adulthood Is Associated With Left Ventricular Remodeling and Dysfunction in Middle Age: The CARDIA Study.

Background: Recent studies have shown that remnant cholesterol (RC) is associated with incident heart failure; however, its association with left ventricular (LV) structure and function is unclear. We aimed to evaluate the association between RC levels in young adulthood and LV structure and function in middle age.

Methods: We included 3321 participants from the CARDIA study (Coronary Artery Risk Development in Young Adults) at baseline.

Association between the insulin resistance and all-cause mortality in patients with moderate and severe aortic stenosis: a retrospective cohort study.

Background: The triglyceride-glucose (TyG) index is a reliable surrogate marker of insulin resistance (IR). However, whether the TyG index has prognostic value in patients with moderate to severe aortic stenosis (AS) remains unclear.

Methods: This study enrolled 317 patients with moderate to severe AS at the First Affiliated Hospital of Sun Yat-Sen University.

Serum Klotho Modifies the Associations of 25-Hydroxy Vitamin D With All-Cause and Cardiovascular Mortality.

Background: The association between 25-hydroxyvitamin D and mortality remains controversial. Klotho, a biomarker of vitamin D activation and metabolism, may play a key role in this association. However, it is unclear whether the association between vitamin D deficiency and mortality risk is modified by klotho levels.

Long-Term High Level of Insulin Resistance Is Associated With an Increased Prevalence of Coronary Artery Calcification: The CARDIA Study.

Background Coronary artery calcification (CAC) is a crucial indicator of subclinical atherosclerotic cardiovascular disease. The relationship between long-term insulin resistance (IR) trajectory and CAC has been explored in few studies. Therefore, this study aimed to investigate whether the long-term IR time series of young adults are associated with the incidence of CAC in midlife.

Predictive performance of established cardiovascular risk scores in the prediabetic population: external validation using the UK Biobank data set.

Aims: Prediabetes is a highly heterogenous metabolic state with increased risk of cardiovascular disease (CVD). Current guidelines raised the necessity of CVD risk scoring for prediabetes without clear recommendations. Thus, this study aimed to systematically assess the performance of 11 models, including five general population-based and six diabetes-specific CVD risk scores, in prediabetes.

Hyperglycemia newly detected by glycated hemoglobin affects all-cause mortality in coronary artery disease patients: a retrospective cohort study.

Aims: We aim to assess the relationship between hyperglycemia and long-term prognosis in CAD patients without known diabetes.

Methods: In this retrospective observational study, we enrolled 11,384 CAD patients without known diabetes. Newly detected diabetes was defined as HbA1c ≥ 6.

High triglyceride-glucose index in young adulthood is associated with incident cardiovascular disease and mortality in later life: insight from the CARDIA study.

Background: This study aimed to investigate the associations between the triglyceride-glucose (TyG) index in young adulthood with incident cardiovascular disease (CVD) and mortality.

Methods: We included 4,754 participants from the Coronary Artery Risk Development in Young Adults study at baseline. The TyG index was calculated as ln (fasting TG [mg/dl] × fasting glucose [mg/dl]/2), and the TyG index trajectories were identified by using the latent class growth mixture model.

Sodium Glucose Cotransporter Type 2 Inhibitors Improve Cardiorenal Outcome of Patients With Coronary Artery Disease: A Meta-Analysis.

Objective: Sodium glucose cotransporter type 2 inhibitors (SGLT-2i) are beneficial for cardiorenal outcomes in patients with type 2 diabetes mellitus (T2DM), heart failure (HF) or chronic kidney disease (CKD). However, whether or not the patients with coronary artery disease (CAD) have prognostic benefit from SGLT-2i treatment has not been fully studied. The purpose of this meta-analysis is to determine the prognostic benefit of SGLT-2i administration in CAD patients.
