Identifying Risk Factors for Lower Extremity Artery Disease (LEAD) in Cardiology Patients: The Role of Ankle-Brachial Index Measurement.

Lower Extremity Artery Disease (LEAD) is a predictor of atherosclerotic plaques in other locations and significantly increases the risk of death from cardiovascular events. This study aimed to identify cardiology patient subpopulations that should undergo Ankle-Brachial Index (ABI) measurement. A total of 800 patients hospitalized in the Department of Cardiology were included.

Pentraxin 3 as a marker of development and severity of stable coronary artery disease.

Purpose: Inflammation plays a crucial role in the development of atherosclerotic plaques. Pentraxin 3 (PTX3) is produced at the site of inflammation and has been identified as a specific marker of atherosclerosis, vascular inflammation, and progression of the coronary artery disease (CAD). The aim of the study was to establish if PTX3 has potential relations with classical markers of cardiovascular risk, and if PTX3 may act as an independent risk factor of CAD occurrence and advancement.

The Importance of Lung Ultrasound and IGFBP7 (Insulin-like Growth Factor Binding Protein 7) Assessment in Diagnosing Patients with Heart Failure.

In daily practice, there are problems with adequately diagnosing the cause of dyspnea in patients with heart failure with preserved and mildly reduced ejection fractions (HFpEF and HFmrEF). This study aimed to assess the usefulness of lung ultrasound in diagnosing HFpEF and HFmrEF and determine its correlation with IGFBP7 (insulin-like growth factor binding protein 7), NTproBNP (N-terminal pro-B-type natriuretic peptide), and echocardiographic markers. The research was conducted on 143 patients hospitalized between 2018 and 2020, admitted due to dyspnea, and diagnosed with HFpEF and HFmrEF.

Myostatin and the Heart.

Myostatin (growth differentiation factor 8) is a member of the transforming growth factor-β superfamily. It is secreted mostly by skeletal muscles, although small amounts of myostatin are produced by the myocardium and the adipose tissue as well. Myostatin binds to activin IIB membrane receptors to activate the downstream intracellular canonical Smad2/Smad3 pathway, and additionally acts on non-Smad (non-canonical) pathways.

Could inflammation contribute to salivary gland dysfunction in patients with chronic heart failure?

Heart failure (HF) is one of the leading causes of death worldwide. HF results not only in cardiovascular dysfunction, but also numerous pathologies in the oral cavity and salivary glands. The present study is the first to evaluate whether salivary inflammatory and anti-inflammatory factors may be related with the occurrence of hyposalivation in HF patients.

Salivary Gland Dysfunction in Patients with Chronic Heart Failure Is Aggravated by Nitrosative Stress, as Well as Oxidation and Glycation of Proteins.

Chronic heart failure (HF) is an important clinical, social, and economic problem. A key role in HF progression is played by oxidative stress. Free oxygen radicals, formed under the conditions of hypoxia and reperfusion, participate in myocardial stunning and other forms of post-reperfusion damage.

Prognostic role of PET/MRI hybrid imaging in patients with pulmonary arterial hypertension.

Objective: Right ventricular (RV) function is a major determinant of survival in patients with pulmonary arterial hypertension (PAH). Metabolic alterations may precede haemodynamic and clinical deterioration. Increased RV fluorodeoxyglucose (FDG) uptake in positron emission tomography (PET) was recently associated with progressive RV dysfunction in MRI, but the prognostic value of their combination has not been established.

Galectin-3 (Gal-3) is a new independent risk factor in the development and severity of coronary artery disease (CAD). The aim of the study was to evaluate whether Gal-3 concentration has prognostic value and if it reflects the progression of atherosclerosis in carotid arteries in patients with CAD after acute myocardial infarction (AMI). The analysis included 110 patients who were hospitalized due to AMI, treated with primary coronary intervention (PCI) and further attended a follow-up visit, and 100 healthy volunteers.

Increased platelet content of SDF-1alpha is associated with worse prognosis in patients with pulmonary prterial hypertension.

Inflammatory processes and platelet activity play an important role in the pathophysiology of pulmonary arterial hypertension (PAH). Enhanced IL-6 signaling and higher concentration of stromal-derived factor alpha (SDF-1) have been previously shown to be linked with prognosis in PAH. We hypothesized that platelets of PAH patients have higher content of IL-6 and SDF-1 and thus are involved in disease progression.

The significance of diminished sTWEAK and P-selectin content in platelets of patients with pulmonary arterial hypertension.

Pulmonary arterial hypertension (PAH) is a progressive disease characterized by proliferative changes in pulmonary arteries. There is growing evidence suggesting that soluble tumor necrosis factor-like weak inducer of apoptosis (sTWEAK) and P-selectin could be involved in PAH development and progression. Here we investigate whether circulating platelets may be a source of sTWEAK and contribute to diminished availability of sTWEAK and P-selectin in PAH patients.

The strengths and weaknesses of non-invasive parameters obtained by echocardiography and cardiopulmonary exercise testing in comparison with the hemodynamic assessment by the right heart catheterization in patients with pulmonary hypertension.

Purpose: Pulmonary hypertension (PH) diagnosis requires invasive assessment by right heart catheterization (RHC), but screening and monitoring are performed using non-invasive methods: echocardiography and cardiopulmonary exercise testing (CPET). The aim of the study was to assess correlations between the parameters obtained in non-invasive testing and RHC in patients with PH of different etiologies.

Material/methods: The study included 53 medical records of PH patients (32 women) aged 29-81 years.
