Acute coronary syndromes

  • In the ASSAIL study we will as the first in the world test if an interleukin-6 antagonist, Toilizumab reduces the size of the myocardial infarct size patients with STEMI heart attack. 200 patients with acute STEMI are randomized to Tocilizumab or placebo. The primary endpoint is infarct size measured by MRI. The study is conducted at the cardiology departments at Oslo University Hospital Rikshospitalet and Ullevål and at St.Olavs Hospital. It will be completed in 2020. The biobank will include blood samples from more than 1700 patients with acute coronary syndromes.

Heart failure

  • GUT-HEART
    Here, we test the hypothesis that altering the gut microbiota with antibiotics or probiotics may improve cardiac function in patients with heart failure. The study is a randomized, controlled and open study with a collaboration with 3 centers in Norway and a center in Rio de Janeiro. 150 patients are included. Will be completed late fall 2019.

Heart transplant patients: 2010-present

  • HITTS
    Randomized study of effects of intensive exercise training vs. conventional follow up during 12 months in de novo heart transplant recipients. Maximal exercise capacity (peak VO2), muscle strength, quality of life, inflammatory variables, echocardiography intravascular ultrasound with measurements of progression of coronary artery vasculopathy. Published in Circulation 2019. We now conduct the 3 year follow up.

Valvular heart disease

  • BAR-study
    2010 - present
    Randomized controlled study on the effects of beta blocker treatment vs. placebo in asymptomatic moderate or severe aortic regurgitation. 75 patients included, will be followed for 6 months. Finished June 2014. Now long term follow up. Echocardiography with 3D and strain measurements, tonometry, ergospirometry.
  • Aortic stenosis in the elderly
    Follow-up study of 500 patients with severe aortic stenosis admitted for intervention. Clinical evaluation, quality of life, echocardiography, functional testing at baseline and 12 months following aortic valve replacement, TAVI or conservative treatment.

    SAS Fibrosis. Myocardial muscle biopsy, echocardiography, MRI and blood samples in 50 patients with AS to evaluate mechanism of disease processes in the valves and myocardium in at least 50 patients with severe disease scheduled for AVR. Collaboration with department of radiology, Institute of Experimental Medical Research, Institute of Internal Medicine.

Arhythmias

  • Effect of treatment of sleep apnea on the burden of atrial fibrillation. We are testing whether treatment of sleep apnea with mask therapy (CPAP) will reduce the burden of atrial fibrillation in patients with paroxysmal atrial fibrillation and sleep apnea. 108 patients with this are randomized to CPAP or control. The burden of atrial fibrillation is measured by a device inserted subcutaneously. The study is conducted at Oslo University Hospital, Rikshospitalet and St.Olavs Hospital. 1 part completed 2019.
