Aim: Correlation of five humoral markers with laboratory, echocardiographic and right heart catheterization parameters in patients with chronic heart failure.
Study Population: 29 patients, heart failure NYHA II and III, ejection fraction below 40% with coronary artery disease or dilated cardiomyopathy.
Methods: evaluation of thromboxane, prostaglandin F (PGF), tumor necrosis factor (TNF) alpha, endothelin-1 and big endothelin rest levels and their correlation with: (1) laboratory parameters: Sodium, urea, creatinine, fibrinogen, (2) chest X-ray: cardiothoracic index (CTI), pulmonary congestion, (3) right heart catheterization parameters at rest, hand-grip and bicycle ergometry: mean pulmonary artery pressure (AP), wedge pressure (WP), systemic and pulmonary vascular resistance (SVR, PVR) and cardiac index (CI), (4) echocardiographic parameters at rest, hand-grip and bicycle ergometry: end-diastolic volume (EDV), end-systolic volume (ESV), ejection fraction (EF), mitral flow E/A, filling period of left ventricle and time of duration of mitral regurgitation.
Results: No correlation was found between thromboxane, prostaglandin F and tumor necrosis factor alpha with the above mentioned parameters. Endothelin-1 level correlated with E/A, PVR and MPA at rest and at hand-grip. Big endothelin level correlated with EDV and ESV, AP, WP and SVR at rest and at both types of exercise. The highest correlation was between big endothelin and rest AP (r=0.79), rest WP (r=0.78) and CTI (r=0.58), all P<0.01.
Conclusions: Big endothelin and partly endothelin-1 levels showed a close correlation with some parameters used for the evaluation of chronic heart failure severity.

Arthropod-borne viral diseases are acute febrile illnesses, sometimes with chronic effects, that can be debilitating and even fatal worldwide, affecting particularly vulnerable populations. Indigenous communities face not only the burden of these acute febrile illnesses, but also the cardiovascular complications that are worsened by urbanization. A cross-sectional study was conducted in an Indigenous population in the Northeast Region of Brazil to explore the association between arboviral infections (dengue, chikungunya, and Zika) and cardiac biomarkers, including cardiotrophin 1, growth differentiation factor 15, lactate dehydrogenase B, fatty-acid-binding protein 3, myoglobin, N-terminal pro-B-type natriuretic peptide, cardiac troponin I, big endothelin 1, and creatine kinase-MB, along with clinical and anthropometric factors.

Astrocytes, vital support cells in the central nervous system (CNS), are crucial for maintaining neuronal health. In neurodegenerative diseases such as Alzheimer's disease (AD), astrocytes play a key role in clearing toxic amyloid-β (Aβ) peptides. Aβ, a potent neuroinflammatory trigger, stimulates astrocytes to release excessive glutamate and inflammatory factors, exacerbating neuronal dysfunction and death.

Despite advances in neonatal and ophthalmological care, retinopathy of prematurity (ROP) continues to be a leading cause of childhood blindness worldwide. Investigating gene variants associated with vascular responses in ROP may provide valuable insights into its pathogenesis and identify risk or protective factors. Nitric oxide (NO) and endothelin-1 (ET-1) play roles in vascular regulation, influencing processes relevant to ROP development.

Purpose: Salvianolate for injection (SFI) is a widely used treatment for acute myocardial infarction (AMI). This study aims to assess the efficacy and safety of SFI in treating AMI by synthesizing evidence from published randomized controlled trials (RCTs).
Methods: Seven databases were searched for relevant RCTs published up to 1 July 2024.

Background: Timely and accurate evaluation of the patient's pulmonary arterial pressure (PAP) is of great significance for the treatment of congenital heart disease. Currently, there is no non-invasive gold standard method for evaluating PAP.
Aim: To assess the prognostic value of lipocalin-2 (LCN2) in relation to PAP in patients with congenital heart disease associated with pulmonary artery hypertension.
