    • Automatic measurements of left ventricular volumes and ejection fraction by artificial intelligence: clinical validation in real time and large databases 

      Olaisen, Sindre Hellum; Smistad, Erik; Espeland, Torvald; Hu, Jieyu; Pasdeloup, David Francis Pierre; Østvik, Andreas; Aakhus, Svend; Rösner, Assami; Malm, Siri; Stylidis, Michael; Holte, Espen; Grenne, Bjørnar Leangen; Løvstakken, Lasse; Dalen, Håvard (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-10-26)
      Aims - Echocardiography is a cornerstone in cardiac imaging, and left ventricular (LV) ejection fraction (EF) is a key parameter for patient management. Recent advances in artificial intelligence (AI) have enabled fully automatic measurements of LV volumes and EF both during scanning and in stored recordings. The aim of this study was to evaluate the impact of implementing AI measurements on acquisition ...

    • Cardiorenal syndrome and the association with fitness: Data from a telerehabilitation randomized clinical trial 

      Langlo, Knut Asbjørn Rise; Lundgren, Kari Margrethe; Zanaboni, Paolo; Mo, Rune; Ellingsen, Øyvind; Hallan, Stein; Aksetøy, Inger-Lise Aamot; Dalen, Håvard (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-05-26)
      Aims To investigate the associations of cardiorespiratory fitness with cardiac, vascular, renal and cardiorenal characteristics in chronic heart failure in a telerehabilitation randomized clinical trial. Secondly, to evaluate the associations of cardiorenal syndrome with the effects of exercise.<p> <p<Methods and results Sixty-nine heart failure patients attended baseline examination, and 61 ...

    • Feasibility of telerehabilitation for heart failure patients inaccessible for outpatient rehabilitation 

      Lundgren, Kari Margrethe; Langlo, Knut Asbjørn Rise; Salvesen, Øyvind; Zanaboni, Paolo; Cittanti, Elisa; Mo, Rune; Ellingsen, Øyvind; Dalen, Håvard; Aksetøy, Inger-Lise Aamot (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-05-23)
      Aims Despite strong recommendations, outpatient cardiac rehabilitation is underused in chronic heart failure (CHF) patients. Possible barriers are frailty, accessibility, and rural living, which may be overcome by telerehabilitation. We designed a randomized, controlled trial to evaluate the feasibility of a 3-month real-time, home-based telerehabilitation, high-intensity exercise programme for ...

    • Intra‐arterial blood pressure traits during and after heavy resistance exercise in healthy males 

      Heitmann, Kim Arne; Dalen, Håvard; Gundersen, Guri Holmen; Ingvaldsen, Rolf Petter; Welde, Boye (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-07-29)
      This randomized within‐subjects crossover‐designed study evaluated intra‐arterial blood pressure (BP) traits in seven healthy males (24 ± 1 years) during heavy resistance exercise (HRE) to failure (10 × 5 repetitions, 5RES) and not to failure (10 × 3 repetitions, 3RES), both at 5RM load. By combining few repetitions, avoidance of Valsalva maneuver, and restricting the duration of each contraction, ...

    • No Effect of Calanus Oil on Maximal Oxygen Uptake in Healthy Participants: A Randomized Controlled Study 

      Tauschek, Lucas Christian; Røsbjørgen, Ragnhild; Dalen, Håvard; Larsen, Terje; Karlsen, Trine (Journal article; Tidsskriftartikkel, 2022-08-23)
      We aimed to investigate the long-term effect of daily Calanus oil supplementation on maximal oxygen uptake (VO<sub>2</sub>max) in healthy 30- to 50-year-old participants. The study was motivated by preclinical studies reporting increased VO<sub>2</sub>max and metabolic health with omega-3 rich Calanus oil. In a double-blinded study, 71 participants were randomized to receive 2 g/day of Calanus or ...
