Advanced heart failure (HF) may occur at any level of left ventricular (LV) ejection fraction
(LVEF). The latter, which is widely utilized for the evaluation of LV systolic performance and …

Background: Low cardiac power output (CPO), measured invasively, can identify critically ill
patients at increased risk of adverse outcomes, including mortality. We sought to determine …

Aims Cardiac and extracardiac abnormalities play important roles in heart failure with
preserved ejection fraction (HFpEF). Biventricular cardiac power output (BCPO) quantifies …

Introduction It is known that maximum oxygen uptake depends on age, sex, endurance
capacity, and chronic heart failure. However, due to the required invasive or often applied …

In this article, we introduce positioning systems in combination with innovative data
processing approaches for estimating external loads and internal demands during …

Introduction: The maximum oxygen consumption (VO2max) is the gold standard in the
cardiorespiratory endurance assessment. Objective: This study aimed to develop a …

Nine ski mountaineering (Ski-Mo), ten Nordic-cross country (NCC), and twelve world elite
biathlon (Bia) athletes were evaluated for cardiopulmonary exercise test (CPET) …

Key points Right heart catheterization data from clinical records of heart transplant patients
are used to identify patient‐specific models of the cardiovascular system. These patient …

Twelve world elite Biathlon (Bia), ten Nordic Cross Country (NCC) and ten ski-
mountaineering (Ski-Mo) athletes were evaluated for pronounced echocardiographic …

Introduction: There is scarce and inconsistent information about gender-related differences
in the hydration of sports persons, as well as about the effects of hydration on performance …
