Background: Biomarkers of endothelial dysfunction, such as soluble E-selectin, and von Willebrand factor (vWf) are elevated in patients with chronic heart failure (CHF). The impact of diabetes mellitus (DM) on these biomarkers, and their relation to prognosis remains unknown.
Aims: to investigate the impact of DM on plasma levels and the prognostic value of E-selectin and vWf in patients with CHF.
Methods And Results: Plasma levels of E-selectin and vWf were measured in 195 CHF patients with (n=48, 24.5%), and without DM, and in 116 age-matched healthy controls. Compared with controls, median plasma E-selectin levels were higher in CHF patients with DM (P=0.012), but not in CHF patients without DM (P=0.45); vWf levels were also higher in CHF patients with DM (P<0.001), but not without DM (P=0.108). E-selectin was associated with risk of recurrent ischaemic cardiovascular events among CHF patients with DM (HR 2.60; P=0.009), but not among patients without DM (HR 1.09; P=0.60) per 1 SD increment in log transformed variable. vWf was not related with outcome in CHF patients with or without DM.
Conclusions: Plasma levels of E-selectin and vWf are elevated in CHF patients with DM but not in those without DM. High E-selectin levels may be associated with ischaemic events in patients with DM.

Exploration of subgroups and associated factors of the uncertainty in illness among older adults with chronic heart failure: A latent profile analysis.

Background: Uncertainty in illness is regarded as a source of stress, and tends to have adverse consequences on quality of life among older adults with chronic heart failure (CHF).
Objective: The purpose of this study was to identify distinct subgroups in uncertainty in illness, and to explore associated factors within the population of older adults with CHF.
Methods: We conducted a cross-sectional study using convenience sampling to survey 311 hospitalized older adults with CHF.
Chronic heart failure (CHF) represents one of the most severe and advanced stages of cardiovascular disease. Despite the critical importance of cardiac rehabilitation (CR) in CHF management, while studies have explored the effectiveness of various CR delivery modes and offered valuable context-specific insights, their relative efficacy remains inconsistent across different patient groups, healthcare environments, and intervention approaches. A clearer understanding requires comprehensive comparisons and in-depth analyses to address these variations.

Aims: Iron deficiency (ID) is highly prevalent in patients with heart failure (HF) and associated with morbidity and poor prognosis, but pathophysiological mechanisms are unknown. We aimed to identify novel biological pathways affected by ID.
Methods And Results: We studied 881 patients with HF from the BIOSTAT-CHF cohort.
Comparative Efficacy and Long-Term Outcomes of Beta-Blockers Alone or in Combination With Angiotensin-Converting Enzyme (ACE) Inhibitors in Chronic Heart Failure: A Systematic Review.

This systematic review provides a comprehensive comparison of beta-blockers and angiotensin-converting enzyme (ACE) inhibitors in the management of chronic heart failure (CHF), with a focus on their long-term efficacy and safety profiles. By synthesizing evidence from randomized controlled trials (RCTs) and clinical studies, the review highlights the significant benefits of both drug classes in reducing mortality and hospital readmissions, and improving patient outcomes. Beta-blockers, such as bisoprolol and carvedilol, demonstrated superior efficacy in reducing sudden cardiac death, particularly in patients with heart failure with reduced ejection fraction (HFrEF).

Dilated cardiomyopathy (DCM), a form of non-ischaemic myocardial disease, is characterised by structural and functional cardiac abnormalities. As defined by the World Health Organisation, DCM constitutes a significant cardiac pathology, leading to increased morbidity and mortality due to complications such as heart failure and arrhythmias. The diagnostic process for DCM predominantly employs echocardiography and MRI, with biomarkers like NT-pro BNP and troponin providing supportive, yet non-specific, evidence.
