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 ... -
Handling of hemolyzed serum samples in clinical chemistry laboratories: The Nordic hemolysis project
Gidske, Gro; Aakre, Kristin Moberg; Rustad, Pål; Sandberg, Sverre; Norling, Anna; Pelanti, Jonna; Henriksen, Gitte; Thorsteinsdóttir, Ingunn; Kristensen, Gunn Berit Berge (Peer reviewed; Journal article, 2019)Hemolysis of blood samples is a pre-analytical challenge that often leads to sample rejection in medical laboratories [1]. Hemolysis occurs when blood cells break down and the intracellular contents leak into the surrounding ... -
High-Sensitivity Cardiac Troponin I and T Response Following Strenuous Activity is Attenuated by Smokeless Tobacco: NEEDED (North Sea Race Endurance Exercise Study) 2014
Skranes, Julia Brox; Kleiven, Øyunn; Aakre, Kristin Moberg; Skadberg, Øyvind; Melberg, Tor Harald; Omland, Torbjørn; Ørn, Stein (Journal article; Peer reviewed, 2020)Background Use of snus, a smokeless tobacco product, is increasing in Scandinavia. Strenuous physical activity is associated with an acute increase in high‐sensitivity cardiac troponin (swhs‐cTn) concentrations. Current ... -
Impact of different preanalytical conditions on results of lupus anticoagulant tests
Kristoffersen, Ann-Helen; Jansrud, Ida; Vannes, Solveig; Åsberg, Arne; Aakre, Kristin Moberg (Peer reviewed; Journal article, 2019)Introduction: The currently recommended preanalytical conditions for lupus anticoagulant (LA) analysis require analyzing samples in fresh or freshly frozen platelet‐poor plasma. The aim of this study was to evaluate whether ... -
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 ... -
Physical activity, exercise and cardiac troponins: Clinical implications
Aakre, Kristin Moberg; Omland, Torbjørn (Peer reviewed; Journal article, 2019)Cardiac troponins constitute essential components of the cardiac contractile apparatus and are released into the bloodstream following cardiomyocyte injury. Because of their cardiac specificity, cardiac troponin I or T are ... -
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 ...
