    Sammanfattning : Atrial fibrillation is a common heart arrhythmia which is characterized by a missing or irregular contraction of the atria. The disease is a risk factor for other more serious diseases and the total medical costs in society are extensive. Therefore it would be beneficial to improve and optimize the prevention and detection of the disease. LÄS MER

    Sammanfattning : Bakgrunn: Diabetes er globalt økende, og et voksende folkehelseproblem. Hovedårsakene er den raske økningen av fedme, fysisk inaktivitet og et økende antall eldre. Samtidig med økt inntakav sukker og kunstige søtningsstoffer, brus og lettbrus, har fedme og diabetestilfeller også økt. LÄS MER
