Cardiac arrhythmia assessment with patch electrocardiogram versus insertable cardiac monitor: a cohort study in endurance athletes with atrial fibrillation.

Objectives: The objective of this study was to assess the quality of ECG recordings and the concordance between the automatic detection of cardiac arrhythmia episodes by a patch ECG and an insertable cardiac monitor.

Design: Prospective cohort study.

Setting And Participants: Endurance athletes diagnosed with paroxysmal atrial fibrillation (AF) and no other relevant comorbidities participating in a randomised controlled trial on the effects of training adaption.

Associations between Growth Differentiation Factor 15, Cardiac Troponin T, and N-terminal pro-B-type Natriuretic Peptide, and Future Myocardial Fibrosis Assessed by Cardiac Magnetic Resonance Imaging: Data from the Akershus Cardiac Examination 1950 Study.

Background: Myocardial fibrosis is associated with a poor outcome for patients with cardiovascular disease (CVD). Growth differentiation factor 15 (GDF-15) concentrations predict the risk of death in patients with CVD, but the underlying pathophysiological mechanisms are poorly understood. We aimed to assess the associations between biomarkers of cellular stress and inflammation (GDF-15), cardiac injury (cardiac troponin T [cTnT]), and stretch (N-terminal pro-B-type natriuretic peptide [NT-proBNP]), and subsequent focal and diffuse myocardial fibrosis assessed by cardiac magnetic resonance (CMR) imaging.

Steaming soil is effective in eliminating invasive alien plants (IAPs) - part I: effect of exposure method.

Background: As regulations on pesticides become more stringent, it is likely that there will be interest in steam as an alternative approach for soil disinfestation. This study investigates the feasibility of utilizing a soil steaming device for thermal control of invasive plants.

Results: Seeds of Echinochloa crus-galli, Impatiens glandulifera, Solidago canadensis, and rhizome fragments of Reynoutria × bohemica were examined for thermal sensitivity through two exposure methods: (1) steam treatment of propagative material in soil; (2) exposure of propagative material to warm soil just after heated by steam.

Cardiac troponin T associates with left ventricular function and synchrony assessed by CMR in the general population: results from the Akershus Cardiac Examination 1950 Study.

Background And Aim: Cardiac troponin T (cTnT) is a blood biomarker of myocardial injury that is associated with future adverse cardiovascular events in the general population. Left ventricular (LV) global longitudinal strain (GLS) and mechanical dispersion (MD) are metrics of systolic function and synchrony that can be obtained from cardiac imaging. Studies suggest an association between cTnT and echocardiographically assessed GLS and MD, but it is unknown whether cTnT relates to these metrics when assessed by cardiac magnetic resonance (CMR).
