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 (Peer reviewed; Journal article, 2020-02)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 ... -
Estimating cardiac output from coronary CT angiography: an individualized compartment model in comparison to the Stewart–Hamilton method
Leiknes, Jon Bjarne; Hiorth, Aksel; Havnen, Jorunn; Greve, Ole Jacob; Kurz, Kathinka Dæhli; Larsen, Alf Inge (Peer reviewed; Journal article, 2023)Background: Attenuation is correlated with the concentration of contrast medium (CM) in the arteries. The cardiac output (CO) affects the concentration of CM in the circulatory system; therefore, CO affects the time–density ... -
Neurofilament light is a biomarker of brain involvement in lupus and primary Sjögren’s syndrome
Tjensvoll, Anne Bolette; Lauvsnes, Maria Boge; Zetterberg, Henrik; Kvaløy, Jan Terje; Kvivik, Ingeborg; Maroni, Stian; Greve, Ole Jacob; Beyer, Mona K.; Hirohata, Shunsei; Putterman, Chaim; Alves, Guido Werner; Harboe, Erna; Blennow, Kaj; Gøransson, Lasse; Omdal, Roald (Peer reviewed; Journal article, 2020-10)Background To test the hypothesis that neurofilament light (NfL) in CSF is a biomarker of CNS involvement in patients with systemic lupus erythematosus (SLE) and primary Sjögren’s syndrome (pSS), we measured NfL in CSF ... -
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 (Journal article; Peer reviewed, 2019-06)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 (Journal article; Peer reviewed, 2019-02)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 ...
