The Association between Progression of Atherosclerosis and the Methylated Amino Acids Asymmetric Dimethylarginine and Trimethyllysine
Løland, Kjetil Halvorsen; Bleie, Øyvind; Borgeraas, Heidi; Strand, Elin; Ueland, Per Magne; Svardal, Asbjørn; Nordrehaug, Jan Erik; Nygård, Ottar (Peer reviewed; Journal article, 2013-05-29)Objective: We previously showed that treatment with folic acid (FA)/B12 was associated with more rapid progression of coronary artery disease (CAD). High doses of FA may induce methylation by increasing the availability ... -

Betaine as a determinant of postmethionine load total plasma homocysteine before and after B-Vitamin supplementation
Holm, Pål Ivar; Bleie, Øyvind; Ueland, Per Magne; Lien, Ernst Asbjørn; Refsum, Helga; Nordrehaug, Jan Erik; Nygård, Ottar (Peer reviewed; Journal article, 2004)Objective—Betaine is a substrate in the betaine– homocysteine methyltransferase reaction, converting homocysteine to methionine. There are only sparse data on plasma betaine as a determinant of the plasma total homocysteine ... -
Effect of Folic Acid Supplementation on Levels of Circulating Monocyte Chemoattractant Protein-1 and the Presence of Intravascular Ultrasound Derived Virtual Histology Thin-Cap Fibroatheromas in Patients with Stable Angina Pectoris
Løland, Kjetil Halvorsen; Bleie, Øyvind; Strand, Elin; Ueland, Per Magne; Nordrehaug, Jan Erik; Garcia-Garcia, Hector M.; Serruys, Patrick W.; Nygård, Ottar (Peer reviewed; Journal article, 2013-07-25)Background: Virtual Histology Intravascular Ultrasound (VH–IVUS) may be used to detect early signs of unstable coronary artery disease. Monocyte Chemoattractant Protein-1 (MCP-1) is linked with coronary atherosclerosis and ... -
Effectiveness, safety, and patient reported outcomes of a planned investment procedure in higher-risk chronic total occlusion percutaneous coronary intervention: Rationale and design of the invest-CTO study
Øksnes, Anja; Skaar, Elisabeth; Engan, Britt; Bleie, Øyvind; Løland, Kjetil Halvorsen; Taoussi, Nadia; Maehara, Akiko; Norekvål, Tone Merete; Rotevatn, Svein; McEntegart, Margaret B. (Journal article; Peer reviewed, 2023)Background: The anatomical complexity of a chronic total occlusion (CTO) correlates with procedural failure and complication rates. CTO modification after unsuccessful crossing has been associated with subsequent higher ... -
Guideline-Recommended Time Less Than 90 Minutes From ECG to Primary Percutaneous Coronary Intervention for ST-Segment–Elevation Myocardial Infarction Is Associated with Major Survival Benefits, Especially in Octogenarians: A Contemporary Report in 11 226 Patients from NORIC
Larsen, Alf Inge; Løland, Kjetil Halvorsen; Hovland, Siren; Bleie, Øyvind; Eek, Christian; Fossum, Eigil; Trovik, Thor; Juliebø, Vibeke; Hegbom, Knut; Moer, Rasmus; Larsen, Tomas; Uchto, Michael; Rotevatn, Svein (Journal article; Peer reviewed, 2022)Background Using contemporary data from NORIC (Norwegian Registry of Invasive Cardiology) we investigated the predictive value of patient age and time from ECG diagnosis to sheath insertion (ECG‐2‐sheath) in primary ... -
A novel Geriatric Assessment frailty score predicts two-year mortality after Transcatheter Aortic Valve implantation
Skaar, Elisabeth; Eide, Leslie Sofia Pareja; Norekvål, Tone M.; Ranhoff, Anette Hylen; Nordrehaug, Jan Erik; Forman, Daniel E.; Schönenberger, Anders; Hufthammer, Karl Ove; Kuiper, Karel Kier-Jan; Bleie, Øyvind; Haaverstad, Rune; Schaufel, Margrethe Aase; Packer, Erik Jerome Stene; Langørgen, Jørund (Peer reviewed; Journal article, 2018-10-31)Aims Established surgical scores have limitations in delineating risk among candidates for transcatheter aortic valve implantation (TAVI). Assessment of frailty might help to estimate the mortality risk and identify patients ... -
Paradoxical sinus deceleration during dobutamine stress echocardiography: case series and review of the literature
Sulo, Enxhela; Davidsen, Einar Skulstad; Lønnebakken, Mai Tone; Bleie, Øyvind; Saeed, Sahrai (Journal article; Peer reviewed, 2022)Background: Dobutamine stress echocardiography is an established diagnostic modality for assessing myocardial ischaemia in patients with known or suspected coronary artery disease. Dobutamine infusion causes dose-dependent ... -
Right ventricular postsystolic shortening: Resolution after opening a totally occluded right coronary artery
Saeed, Sahrai; Karaji, Iman; Skromme, Kaia; Øksnes, Anja; Larsen, Terje Hjalmar; Bleie, Øyvind (Journal article; Peer reviewed, 2022)Acute myocardial ischemia induces reduced systolic shortening and causes postsystolic shortening (PSS). Right ventricular (RV) PSS in coronary artery disease has been less studied. We present here the case of a 51-year-old ... -
