“Atrial Fibrillation: A prospective population study of risk factors and complications. The Tromsø Study”
Kort sammendrag av avhandlingen:
Atrial fibrillation is a common heart disease and may increase the risk of serious health complications. In the population based Tromsø Study we investigated which risk factors increased the risk of future atrial fibrillation, and which complications people with atrial fibrillation get by following them over many years. Our focus was particularly the size of the heart’s left atrium as an atrial fibrillation risk factor, atrial fibrillation as risk factor for stroke, and cognitive function decline in subjects with atrial fibrillation without stroke. We found that enlarged left atrium size of the heart as measured by echocardiography gave a fourfold increased risk for atrial fibrillation in both sexes. In addition, individuals with enlarged left atrium and at least one risk factor for stroke had nine times higher stroke risk irrespective of whether they had atrial fibrillation or not. In stroke free participants, subjects with atrial fibrillation had 40% increased cognitive decline.
