    • 3-Weeks of Exercise Training Increases Ischemic-Tolerance in Hearts From High-Fat Diet Fed Mice 

      Boardman, Neoma Tove; Rossvoll, Line; Lund, Jim; Hafstad, Anne Dragøy; Aasum, Ellen (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-10-02)
      Physical activity is an efficient strategy to delay development of obesity and insulin resistance, and thus the progression of obesity/diabetes-related cardiomyopathy. In support of this, experimental studies using animal models of obesity show that chronic exercise prevents the development of obesity-induced cardiac dysfunction (cardiomyopathy). Whether exercise also improves the tolerance to ...

    • NADPH oxidase 2 mediates myocardial oxygen wasting in obesity 

      Hafstad, Anne Dragøy; Hansen, Synne Simonsen; Lund, Jim; Santos, Celio X.C.; Boardman, Neoma Tove; Shah, Ajay M.; Aasum, Ellen (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-02-19)
      Obesity and diabetes are independent risk factors for cardiovascular diseases, and they are associated with the development of a specific cardiomyopathy with elevated myocardial oxygen consumption (MVO<sub>2</sub>) and impaired cardiac efficiency. Although the pathophysiology of this cardiomyopathy is multifactorial and complex, reactive oxygen species (ROS) may play an important role. One of the ...
