Determinants of interindividual variation in exercise-induced cardiac troponin I levels
Bjørkavoll-Bergseth, Magnus; Erevik, Christine Bjørkvik; Kleiven, Øyunn; Eijsvogels, Thijs M. H.; Skadberg, Øyvind; Frøysa, Vidar; Wiktorski, Tomasz; Auestad, Bjørn; Edvardsen, Thor; Aakre, Kristin Moberg; Ørn, Stein (Journal article; Peer reviewed, 2021)Background: Postexercise cardiac troponin levels show considerable interindividual variations. This study aimed to identify the major determinants of this postexercise variation in cardiac troponin I (cTnI) following 3 ... -
Duration of elevated heart rate Is an important predictor of exercise-induced troponin elevation
Bjørkavoll-Bergseth, Magnus; Kleiven, Øyunn; Auestad, Bjørn Henrik; Eftestøl, Trygve Christian; Oskal, Kay Raymond; Nygård, Martin; Skadberg, Øyvind; Aakre, Kristin Moberg; Melberg, Tor Harald; Gjesdal, Knut; Ørn, Stein (Journal article; Peer reviewed, 2020)Background The precise mechanisms causing cardiac troponin (cTn) increase after exercise remain to be determined. The aim of this study was to investigate the impact of heart rate (HR) on exercise‐induced cTn increase by ... -
Endurance exercise training volume is not associated with progression of coronary artery calcification
Kleiven, Øyunn; Bjørkavoll-Bergseth, Magnus; Omland, Torbjørn; Aakre, Kristin Moberg; Frøysa, Vidar; Erevik, Christine B.; Greve, Ole Jacob; Melberg, Tor Harald; Auestad, Bjørn Henrik; Skadberg, Øyvind; Edvardsen, Thor; Ørn, Stein (Journal article; Peer reviewed, 2020)Background Recent cross‐sectional studies have suggested a dose‐dependent relationship between lifelong exposure to physical activity and the burden of calcified coronary artery disease (CAD). No longitudinal studies have ... -
Occult obstructive coronary artery disease is associated with prolonged cardiac troponin elevation following strenuous exercise
Kleiven, Øyunn; Omland, Torbjørn; Skadberg, Øyvind; Melberg, Tor Harald; Bjørkavoll-Bergseth, Magnus; Auestad, Bjørn Henrik; Bergseth, Rolf; Greve, Ole Jacob; Aakre, Kristin Moberg; Ørn, Stein (Peer reviewed; Journal article, 2019)Background: Sudden cardiac death among middle-aged recreational athletes is predominantly due to myocardial ischaemia. This study examined whether measuring cardiac troponin I and T (cTnI and cTnT) after strenuous exercise ... -
Race duration and blood pressure are major predictors of exercise-induced cardiac troponin elevation
Kleiven, Øyunn; Omland, Torbjørn; Skadberg, Øyvind; Melberg, Tor Harald; Bjørkavoll-Bergseth, Magnus; Auestad, Bjørn Henrik; Bergseth, Rolf; Greve, Ole Jacob; Aakre, Kristin Moberg; Ørn, Stein (Peer reviewed; Journal article, 2019)Background: The underlying mechanisms of the exercise-induced increase in cardiac troponins (cTn) are poorly understood. The aim of this study was to identify independent determinants of exercise-induced cTn increase in a ... -
The relationship between exercise-induced cardiac Troponin increase and physical workload during prolonged strenuous exercise : North Sea Endurance Exercise Study (NEEDED) 2018
Bjørkavoll-Bergseth, Magnus (Doctoral thesis, 2024-06-06)Bakgrunn Høye nivåer av kardial troponin (cTn) er knyttet til økt dødelighet og en høyere sjanse for udiagnostisert koronararteriesykdom (CAD). Denne avhandlingen hadde som mål å undersøke sammenhengen mellom treningsintensitet ... -
The relationship between workload and exercise-induced cardiac troponin elevations is influenced by non-obstructive coronary atherosclerosis
Bjørkavoll-Bergseth, Magnus; Erevik, Christine Bjørkvik; Kleiven, Øyunn; Wiktorski, Tomasz; Auestad, Bjørn Henrik; Skadberg, Øyvind; Aakre, Kristin Moberg; Eijsvogels, Thijs M. H.; Ørn, Stein (Journal article; Peer reviewed, 2024)The relationship between exercise-induced troponin elevation and non-obstructive coronary artery disease (CAD) is unclear. This observational study assessed non-obstructive CAD's impact on exercise-induced cardiac Troponin ...
