Background: Postexercise release of cardiac biomarkers (cardiac troponins, cTn, and N-
terminal pro b-type natriuretic peptide, NT-proBNP) is a well-known phenomenon in adults …

Sustained physical activity induces morphological and functional changes in the
cardiovascular system. While mostly physiological, they can also become a trigger for major …

Purpose We aimed at exploring whether cardiopulmonary fitness, echocardiographic
measures and relative exercise intensity were associated with high-sensitivity cardiac …

Aims Endurance sports practice has significantly increased over the last decades, with a
growing proportion of participants older than 40 years. Although the benefits of moderate …

The impact of ultramarathon (UM) runs on the organs of competitors, especially elite
individuals, is poorly understood. We tested a 36-year-old UM runner before, 1–2 days after …

Constant and intense physical activity causes physiological adaptive changes in the human
body, but it can also become a trigger for adverse events, such as sudden cardiac arrest or …

Aim: To provide a state-of-the-art review of the last 10 years focusing on cardiac fatigue
following a marathon. Methods: The PubMed, Bookshelf and Medline databases were …

Purpose: In this study, we investigated the effect of treadmill exercise training on cardiac
hypertrophy, collagen deposition, echo parameters and serum levels of cardiac troponin I …

Background Cardiac troponins (cTn) have been reported to be predictors for adverse
outcomes in atrial fibrillation (AF), patients, but their actual use is still unclear. Aim To assess …

Background. Cardiovascular safety of marathon running middle-aged amateurs remains
unclear. We previously hypothesized that transient release of cardiac troponin I (cTnI) and N …
