Automatic Estimation of Coronary Blood Flow Velocity Step 1 for Developing a Tool to Diagnose Patients With Micro-Vascular Angina Pectoris
Khanmohammadi, Mahdieh; Sæland, Charlotte; Engan, Kjersti; Eftestøl, Trygve Christian; Larsen, Alf Inge (Journal article; Peer reviewed, 2019-01)Aim: Our aim was to automatically estimate the blood velocity in coronary arteries using cine X-ray angiographic sequence. Estimating the coronary blood velocity is a key approach in investigating patients with angina ... -
Burden of treatment in patients with chronic heart failure – A cross-sectional study
Nordfonn, Oda Karin; Morken, Ingvild Margreta; Bru, Lars Edvin; Larsen, Alf Inge; Husebø, Anne Marie Lunde (Peer reviewed; Journal article, 2021-02)Background Patients with heart failure (HF) must manage both a demanding treatment regimen and self-care, which may lead to a burden of treatment. The purpose of this study was to assess the levels of burdens from treatment ... -
Effects of purified anthocyanins in people at risk for dementia: Study protocol for a phase II randomized controlled trial
Khalifa, Khadija; Bergland, Anne Katrine; Sønnesyn, Hogne; Oppedal, Ketil; Oesterhus, Ragnhild; Dalen, Ingvild; Larsen, Alf Inge; Fladby, Tormod; Brooker, Helen; Wesnes, Keith A.; Ballard, Clive; Aarsland, Dag (Peer reviewed; Journal article, 2020)Background: The number of people with dementia is increasing, with huge challenges for society and health-care systems. There are no disease-modifying therapies available. There is, therefore, an urgent need to identify ... -
Estimating cardiac output from coronary CT angiography: an individualized compartment model in comparison to the Stewart–Hamilton method
Leiknes, Jon Bjarne; Hiorth, Aksel; Havnen, Jorunn; Greve, Ole Jacob; Kurz, Kathinka Dæhli; Larsen, Alf Inge (Peer reviewed; Journal article, 2023)Background: Attenuation is correlated with the concentration of contrast medium (CM) in the arteries. The cardiac output (CO) affects the concentration of CM in the circulatory system; therefore, CO affects the time–density ... -
Plasma tumour necrosis factor correlates with mRNA expression of tumour necrosis factor and mitochondrial transcription factors in skeletal muscle in patients with chronic heart failure treated with cardiac resynchronization therapy: potential role in myopathy
Larsen, Alf Inge; Valborgland, Torstein; Ogne, Christer; Lindal, Sigurd; Halvorsen, Bente; Munk, Peter Scott; Kvaløy, Jan Terje; Aukrust, Pål; Yndestad, Arne (Journal article; Peer reviewed, 2019-06)Chronic heart failure (CHF) is characterized by inflammation and skeletal muscle myopathy, including impaired fibre type distribution and reduced capillary density, reduced cytochrome oxidase activity and reduced mitochondrial ... -
Reassured on a background of vulnerability - people with microvascular angina 12 months after high-intensity physical exercise program
Røysland, Ingrid Ølfarnes; Ueland, Venke Irene; Larsen, Alf Inge (Peer reviewed; Journal article, 2022)Purpose Physical activity is recommended for patients with coronary microvascular dysfunction, however, avoided due to fear about the heart. The aim is to achieve an understanding of the meaning of physical activity one ... -
The localization and characterization of ischemic scars in relation to the infarct related coronary artery assessed by cardiac magnetic resonance and a novel automatic postprocessing method
Woie, Leik; Engan, Kjersti; Eftestøl, Trygve; Larsen, Alf Inge; Ørn, Stein (Journal article; Peer reviewed, 2015-09)Aims . The correspondence between the localization and morphology of ischemic scars and the infarct related artery (IRA) by use of cardiac magnetic resonance imaging and a novel automatic postprocessing method. Methods ...
