Kristoffer Andresen

  • Consultant Cardiologist; MD

Kristoffer Andresen, MD, Specialist in Internal Medicine and Cardiology, Consultant Cardiologist and Head of Section, Oslo University Hospital Rikshospitalet.

Andresen received his medical degree at NTNU in Trondheim in 2010. After having completed his internship in 2012, he worked at the Department of Internal Medicine at Drammen Hospital until 2018 and has further been working at Oslo University Hospital Rikshospitalet. He is a certified specialist in Internal Medicine and Cardiology and is currently working as a Consultant Cardiologist at the Department of Cardiology and Head of Section for doctors in specialist education.

Andresens PhD research is titled “Novel imaging modalities for myocardial tissue characterisation” and focusses on non-invasive myocardial tissue characterisation by echocardiography and cardiovascular magnetic resonance imaging in athletes and patients with cardiac disease. The aims of the project are to fill existing research gaps regarding myocardial fibrosis in athletes and patients with cardiac diseases as well as to enhance non-invasive myocardial tissue characterisation by mechanical wave imaging using high frame rate echocardiography.

Supervisors: Professor Thor Edvardsen, MD, PhD and Associate Professor Kristina Hermann Haugaa, MD, PhD.
