      Morseth, Bente; Løchen, Maja-Lisa; Ariansen, Inger Kristine Holtermann; Myrstad, Marius; Thelle, Dag Steinar (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-02-07)
      Although commonly associated with cardiovascular disease or other medical conditions, atrial fibrillation may also occur in individuals without any known underlying conditions. This manifestation of atrial fibrillation has been linked to extensive and long-term exercise, as prolonged endurance exercise has shown to increase prevalence and risk of atrial fibrillation. In contrast, more modest physical ...
    • Association between espresso coffee and serum total cholesterol: the Tromsø Study 2015-2016 

      Svatun, Åsne Lirhus; Løchen, Maja-Lisa; Thelle, Dag Steinar; Wilsgaard, Tom (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-05-10)
      Background - Coffee raises serum cholesterol because of its diterpenes, cafestol and kahweol, and the effect varies by brewing method. Population-based research on espresso coffee’s impact on serum cholesterol is scarce. Our aim was to examine how various brewing methods, in particular espresso, were associated with serum total cholesterol (S-TC).<p> <p>Methods - We used cross-sectional population ...
    • Data on gender contrasts in the risk of incident myocardial infarction by age. The Tromsø Study 1979–2012 

      Albrektsen, Grethe; Heuch, Ivar; Løchen, Maja-Lisa; Thelle, Dag Steinar; Wilsgaard, Tom; Njølstad, Inger; Bønaa, Kaare Harald (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-07-08)
      The data presented in this article relate to the research article entitled “Risk of incident myocardial infarction by gender: Interactions with serum lipids, blood pressure and smoking. The Tromsø Study 1979–2012” (Albrektsen et al., 2017) [1]. Data quantify the gender differences in the risk of myocardial infarction (MI) in terms of incidence rate ratios (IRR), in subgroups defined by serum lipids, ...
    • Increased risk of atrial fibrillation among elderly Norwegian men with a history of long-term endurance sport practice 

      Myrstad, Marius; Løchen, Maja-Lisa; Graff-Iversen, Sidsel; Gulsvik, Anne Kristine; Thelle, Dag Steinar; Stigum, Hein; Ranhoff, Anette Hylen (Journal article; Tidsskriftartikkel; Peer reviewed, 2013-11-21)
      Atrial fibrillation (AF) is the most common cardiac arrhythmia. The prevalence increases with increasing age. In middle-aged men, endurance sport practice is associated with increased risk of AF but there are few studies among elderly people. The aim of this study was to investigate the role of long-term endurance sport practice as a risk factor for AF in elderly men. A crosssectional study ...
    • Lipid Levels During Adult Lifetime in Men and Women With and Without a Subsequent Incident Myocardial Infarction: A Longitudinal Analysis of Data From the Tromsø Study 1974 to 2016 

      Albrektsen, Grethe; Wilsgaard, Tom; Heuch, Ivar; Løchen, Maja-Lisa; Thelle, Dag Steinar; Njølstad, Inger; Grimsgaard, Sameline; Bønaa, Kaare Harald (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-07-14)
      Background - The atherosclerotic effect of an adverse lipid profile is assumed to accumulate throughout life, leading to increased risk of myocardial infarction (MI). Still, little is known about age at onset and duration of unfavorable lipid levels before MI.<p> <p>Methods and Results - Longitudinal data on serum lipid levels for 26 130 individuals (50.5% women, aged 20–89 years) were obtained ...
    • Physical activity, resting heart rate, and atrial fibrillation: the Tromsø Study 

      Morseth, Bente; Graff-Iversen, Sidsel; Jacobsen, Bjarne K.; Jørgensen, Lone; Nyrnes, Audhild; Thelle, Dag Steinar; Vestergaard, Peter; Løchen, Maja-Lisa (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-03-10)
      Aims: The objective was to examine the association of physical activity and resting heart rate (RHR) with hospital-diagnosed atrial fibrillation (AF) in a Norwegian cohort. <p> Methods and Results: This prospective study included 20 484 adults (50.3% men) who participated in the third Tromsø Study survey in 1986-1987. At baseline, physical activity was assessed by a validated questionnaire, and ...
    • Risk of atrial fibrillation and stroke among older men exposed to prolonged endurance sport practice: a 10-year follow-up. The Birkebeiner Ageing Study and the Tromsø Study 

      Johansen, Kristoffer Robin; Ranhoff, Anette Hylen; Sørensen, Eivind; Nes, Bjarne; Heitmann, Kim Arne; Apelland, Turid; Bucher Sandbakk, Silvana; Wilsgaard, Tom; Løchen, Maja-Lisa; Thelle, Dag Steinar; Morseth, Bente; Myrstad, Marius (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-11-17)
      <p><b> Aims</b> Endurance sport practice is associated with a high prevalence of atrial fibrillation (AF), which increases the risk of stroke in the general population. However, stroke risk in endurance athletes with AF is sparsely investigated. Most studies have been limited by design and are largely restricted to younger and middle-aged populations. Thus, we aimed to investigate AF and stroke ...
    • Ten-year mortality among older male recreational endurance athletes in the Birkebeiner Aging Study in comparison with older men from the Tromsø Study 

      Johansen, Kristoffer Robin; Hylen Ranhoff, Anette; Sørensen, Eivind; Nes, Bjarne Martens; Sandbakk, Silvana Bucher; Wilsgaard, Tom; Løchen, Maja-Lisa; Thelle, Dag Steinar; Morseth, Bente; Myrstad, Marius (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-05-10)
      Background: Physical activity (PA) is associated with reduced mortality. However, whether there is an added benefit of long-term endurance training is unclear. Thus, we aimed to examine 10-year mortality in older male endurance athletes compared with an older male general population. <p><p>Method: Male athletes (n=503) participating in an annual long-distance ski race (median years of participation: ...
