The study aimed to examine the influence of COVID-19 on the adoption of teleservices in Poland, with a focus on contrasting patterns between rehabilitation and ambulatory care settings. We conducted a retrospective analysis of a national dataset to assess trends in telehealth use from 2020 to 2022. The use of teleservices peaked in April 2020 in both sectors.

Introduction: Bioelectrical impedance analysis is a widely available, non-invasive method for body composition assessment.

Aim: To elucidate the perioperative body composition alterations and their prognostic utility for hospital length of stay (LOS) in low risk, off-pump coronary artery bypass (OPCAB) patients.

Material And Methods: Fifty patients undergoing elective OPCAB were included in the study.

Background: Despite the positive effects of endurance training on the cardiovascular (CV) system, excessive exercise induces not only physiological adaptations but also adverse changes in CV system, including the heart. We aimed to evaluate the selected miRNAs expression based on bioinformatic analysis and their changes before and after an ultramarathon run.

Materials And Methods: Cardiac tissue-specific targets were identified with the Tissue 2.

The aim of the study was to assess the role of cardiovascular magnetic resonance (CMR) in the diagnosis of idiopathic VA in children. This retrospective single-centre study included a total of 80 patients with idiopathic ventricular arrhythmia that underwent routine CMR imaging between 2016 and 2020 at our institution. All patients underwent a 3.

A better understanding of the left ventricle (LV) and right ventricle (RV) functioning would help with the differentiation between athlete's heart and dilated cardiomyopathy (DCM). We aimed to analyse deformation parameters in endurance athletes relative to patients with DCM using cardiac magnetic resonance feature tracking (CMR-FT). The study included males of a similar age: 22 ultramarathon runners, 22 patients with DCM and 21 sedentary healthy controls (41 ± 9 years).
