    • 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 ...

    • 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 (Journal article; Peer reviewed, 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 ...

    • Hepatoid adenocarcinoma of the stomach - Proper identification and treatment remain a challenge 

      Søreide, Jon Arne; Greve, Ole Jacob; Gudlaugsson, Einar; Størset, Svein (Peer reviewed; Journal article, 2016)
      Objective: The term hepatoid adenocarcinoma (HAC) of the stomach was introduced three decades ago with the observation of high serum α-fetoprotein (AFP) levels in some gastric adenocarcinoma patients. This very rare gastric ...

    • 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 (Journal article; Peer reviewed, 2020)
      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 (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 ...

    • Percutaneous cholecystostomy – An option in selected patients with acute cholecystitis 

      Søreide, Jon Arne; Fjetland, Anja Maria; Desserud, Kari Festøy; Greve, Ole Jacob; Fjetland, Lars (Journal article; Peer reviewed, 2020-05)
      While urgent percutaneous cholecystostomy (PC) was introduced as an alternative to acute surgical treatment for acute cholecystitis (AC), the current place of PC in the treatment algorithm for AC is challenged. We evaluate ...

    • 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 ...

    • Relationship between Orthostatic Hypotension and White Matter Hyperintensity Load in Older Patients with Mild Dementia 

      Sønnesyn, Hogne; Nilsen, Dennis W. T.; Oppedal, Ketil; Greve, Ole Jacob; Beyer, Mona K.; Aarsland, Dag (Peer reviewed; Journal article, 2012-12-19)
      Background/Objectives: White matter hyperintensities (WMH) in magnetic resonance imaging (MRI) scans of the brain, and orthostatic hypotension (OH) are both common in older people. We tested the hypothesis that OH is ...

    • White Matter Hyperintensities and the Course of Depressive Symptoms in Elderly People with Mild Dementia 

      Sønnesyn, Hogne; Oppedal, Ketil; Greve, Ole Jacob; Fritze, Friederike; Auestad, Bjørn Henrik; Nore, Sabine; Beyer, Mona K.; Aarsland, Dag (Peer reviewed; Journal article, 2012)
      Objectives: To explore the relationship between white matter hyperintensities (WMH) and the prevalence and course of depressive symptoms in mild Alzheimer’s disease (AD) and Lewy body dementia. Design: This is a prospective ...
