Atrial fibrillation is associated with cognitive decline in stroke-free subjects: the Tromsø Study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-09-28)
Background and purpose:<br>Previous studies have shown associations between atrial fibrillation (AF) and cognitive decline. We investigated this association in a prospective population study, focusing on whether stroke risk factors modulated this association in stroke-free women and men.<br>Methods:<br>We included 4983 participants (57% women) from the fifth survey of the Tromsø Study (Tromsø 5, ...
The phosphodiesterase 8B gene rs4704397 is associated with thyroid function, risk of myocardial infarction and body height. The Tromsø Study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
Objective: High serum thyrotropin (TSH) levels predict cardiovascular disease (CVD). Recently several single nucleotide polymorphisms (SNPs) associated with TSH levels have been identified, one of them being the rs4704397 SNP in the phosphodiesterase 8B (PDE8B) gene. If the relation between thyroid function and CVD is causal, one could also expect rs4704397 genotypes to predict CVD and possibly ...
Left atrial diameter, left ventricle filling indices, and association with all-cause mortality: Results from the population-based Tromsø Study.
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-01-28)
<p><i>Aims</i>: To examine the associations between diastolic dysfunction indices and long‐term risk of all‐cause mortality in adults over 23‐year follow‐up.</p> <p><i>Methods and results</i>: Participants (n = 2734) of the population‐based Tromsø Study of Norway had echocardiography in 1994–1995. Of these 67% were repeated in 2001 and/or 2007–2008. Mortality between 1994 and 2016 was determined ...
Atherosclerotic risk factors and risk of myocardial infarction and venous thromboembolism; Time-fixed versus time-varying analyses. The Tromsø Study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-09-16)
<i>Background:</i> Single measurements of modifiable risk factors may underestimate associations with outcomes in cohorts. We aimed to compare risk estimates of myocardial infarction (MI) and venous thromboembolism (VTE) by atherosclerotic risk factors during long follow-up using time-fixed analyses without and with correction for regression dilution and time-varying analyses.<p> <p><i>Methods:</i> ...
Ischemic Stroke and Risk of Venous Thromboembolism in the General Population: The Tromsø Study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-11-07)
<i>Background</i> - Even though clinical data support a relation between ischemic stroke and venous thromboembolism (VTE), the strength and time dependence of the association remain to be settled at the population level. We therefore aimed to investigate the association between ischemic stroke and VTE in a prospective population-based cohort.<p> <p><i>Methods and Results</i> - Participants (n=30 ...
Effect of genetically low 25-hydroxyvitamin D on mortality risk: Mendelian randomization analysis in 3 large European cohorts
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-01-02)
The aim of this study was to determine if increased mortality associated with low levels of serum 25-hydroxyvitamin D (25(OH)D) reflects a causal relationship by using a Mendelian randomisation (MR) approach with genetic variants in the vitamin D synthesis pathway. Individual participant data from three European cohorts were harmonized with standardization of 25(OH)D according to the Vitamin D ...
