The aim of the study was to find out scientific evidence on the possible use of the combined angiotensin II receptor antagonist and neprilysin inhibitors (ARNI) in patients with right heart failure (RHF) in the course of chronic obstructive pulmonary disease (COPD). It has been proven that a lack of neprilysin or its reduced expression in hypoxia leads to exacerbation of pulmonary arterial remodelling (PAR) or pulmonary hypertension (PH) in the mechanism related to the platelet-derived growth factor (PDGF) resulting in the proliferation and migration of pulmonary artery smooth muscle cells and endothelial-to-mesenchymal transition...

AIM: Epidermal growth factor receptor (EGFR) related reactive oxygen species (ROS) generation results in myocardial damage. We aimed to investigate the role of gefitinib (EGFR-tyrosine kinase inhibitor) in diabetic cardiomyopathy (DbCM). METHOD: DbCM was induced by injecting streptozotocin (55 mg/kg for 5 consecutive days) to C57/BL6 mice intraperitoneally. Diabetic C57/BL6 mice (fasting blood glucose level ≥ 250 mg/dl) were allocated into four study groups and treated with two doses of gefitinib (30 mg/kg and 350 mg/kg per day) as well as ramipril (3 mg/kg/day) for four weeks...

BACKGROUND: High mortality in peritoneal dialysis (PD) patients is associated with the presence of nontraditional cardiovascular risk factors, such as malnutrition. However, hypoalbuminemia in patients undergoing PD may have gender-dependent consequences. OBJECTIVES: The aim of the study was to evaluate the relationship between hypoalbuminemia, overhydration (OH), inflammation, and cardiovascular risk, depending on gender. MATERIAL AND METHODS: The group studied consisted of 54 PD patients: 26 male (mean age: 59 ±19 years) and 28 female (mean age: 52 ±15 years) patients...

Pulse pressure (PP) is a risk factor for cardiovascular diseases and is associated with increased afterload and myocardial oxygen demand. Brain natriuretic peptide (BNP) and heart-type fatty acid-binding protein (H-FABP) are known as biomarkers indicating ventricular wall stress and silent myocardial damage. However, the association between PP and ventricular wall stress and silent myocardial damage in the general population is unclear. The authors enrolled 3504 patients who participated in a community-based annual health check...

BACKGROUND: Heart rate (HR) assessed by electrocardiogram (ECG-HR) and pulse rate (PR) measured in a physician's office (office-PR) are taken with subjects in different body positions-i.e., supine vs. sitting. Although analysis of HR differences according to body position could provide new practical insights, there have been few studies on the subject. We herein investigated whether the difference between office-PR and ECG-HR (delta HR) was associated with brain natriuretic peptide (BNP) levels and left ventricular mass (LVM)...

Clinical and experimental studies indicate a possible link between high serum levels of fibroblast growth factor 23 (FGF23), phosphate, and parathyroid hormone (PTH), deficiency of active vitamin D (1,25D) and klotho with the development of pathological cardiac remodeling, i.e., left ventricular hypertrophy and myocardial fibrosis, but a causal link has not been established so far. Here, we investigated the cardiac phenotype in klotho hypomorphic ( kl/kl ) mice and Hyp mice, two mouse models of elevated FGF23 levels and klotho deficiency, but differing in parameters of mineral metabolism, by using histology, quantitative real-time PCR, immunoblot analysis, and serum and urine biochemistry...

Pulmonary arterial hypertension (PAH) is a severe complication of systemic sclerosis (SSc) associated with high morbidity and mortality. There are several biomarkers of SSc-PAH, reflecting endothelial physiology, inflammation, immune activation, extracellular matrix, metabolic changes, or cardiac involvement. Biomarkers associated with diagnosis, disease severity and progression have been identified, however, very few have been tested in a prospective setting. Some antinuclear antibodies such as nucleosome antibodies (NUC), anti-centromere antibodies (CENP-A/B) and anti-U3-ribonucleoprotein (anti-U3-RNP) are associated with PAH while anti-U1-ribonucleoprotein (anti-U1-RNP) is associated with a reduced PAH risk...

BACKGROUND: Left ventricular hypertrophy (LVH) increases the risk of death in chronic kidney disease (CKD). The transcription factor Kruppel-like factor 15 (KLF15) is expressed in the heart and regulates cardiac remodelling through inhibition of hypertrophy and fibrosis. It is unknown if KLF15 expression is changed in CKD induced LVH, or whether expression is modulated by blood pressure reduction using angiotensin converting enzyme (ACE) inhibition. METHODS: CKD was induced in Sprague-Dawley rats by subtotal nephrectomy (STNx), and rats received vehicle (n = 10) or ACE inhibition (ramipril, 1 mg/kg/day, n = 10) for 4 weeks...

Cyclic guanosine monophosphate (cGMP) is synthesized by two types of enzymes: particulate (membrane-bound) guanylyl cyclases (pGCs) and soluble (cytosolic) guanylyl cyclases (sGCs). sGCs are primarily activated by binding of nitric oxide to their prosthetic heme group while pGCs are activated by binding of peptide ligands to their extracellular domains. One of them, pGC type A (GC-A) is activated by atrial and brain natriuretic peptides (ANP and BNP, respectively). Human monocytes isolated from peripheral blood mononuclear cells have been found to display sGC expression without concomitant expression of GC-A...
