Serum Acylcarnitines and Risk of Cardiovascular Death and Acute Myocardial Infarction in Patients With Stable Angina Pectoris
Strand, Elin; Pedersen, Eva Ringdal; Svingen, Gard Frodahl Tveitevåg; Olsen, Thomas; Bjørndal, Bodil; Karlsson, Therese; Dierkes, Jutta; Njølstad, Pål Rasmus; Mellgren, Gunnar; Tell, Grethe S.; Berge, Rolf Kristian; Svardal, Asbjørn M.; Nygård, Ottar (Peer reviewed; Journal article, 2017-02)Background: Excess levels of serum acylcarnitines, which are intermediate products in metabolism, have been observed in metabolic diseases such as type 2 diabetes mellitus. However, it is not known whether acylcarnitines ... -
Systemic Cardiac Troponin T Associated With Incident Atrial Fibrillation Among Patients With Suspected Stable Angina Pectoris
Vavik, Vegard; Pedersen, Eva Ringdal; Svingen, Gard Frodahl Tveitevåg; Solheim, Eivind; Aakre, Kristin Moberg; Tell, Grethe S.; Nygård, Ottar; Vikenes, Kjell (Journal article; Peer reviewed, 2020)Higher concentrations of cardiac troponin T are associated with coronary artery disease (CAD) and adverse cardiovascular prognosis. The relation with incident atrial fibrillation (AF) is less explored. We studied this ... -
Transsulfuration metabolites and the association with incident atrial fibrillation – An observational cohort study among Norwegian patients with stable angina pectoris
Svenningsson, Mads Malm; Svingen, Gard Frodahl Tveitevåg; Lysne, Vegard; Ueland, Per Magne; Tell, Grethe S.; Pedersen, Eva Ringdal; Dhar, Indu; Nilsen, Dennis W.T.; Nygård, Ottar (Journal article; Peer reviewed, 2020)Background/aim Plasma total homocysteine (tHcy) is elevated in patients with persistent vs. paroxysmal atrial fibrillation (AF), and has been related to increased risk of new-onset AF. Homocysteine is degraded to cystathionine ... -
Trimethyllysine predicts all-cause and cardiovascular mortality in community-dwelling adults and patients with coronary heart disease
Bjørnestad, Espen Øglænd; Dhar, Indu; Svingen, Gard Frodahl Tveitevåg; Pedersen, Eva Kristine Ringdal; Svenningsson, Mads Malm; Tell, Grethe Seppola; Ueland, Per Magne; Ørn, Stein; Sulo, Gerhard; Laaksonen, Reijo; Nygård, Ottar Kjell (Journal article; Peer reviewed, 2021)Aims Trimethyllysine (TML) is involved in carnitine synthesis, serves as a precursor of trimethylamine N-oxide (TMAO) and is associated with cardiovascular events in patients with established coronary heart disease (CHD). ... -
Use of loop diuretics is associated with increased mortality in patients with suspected coronary artery disease, but without systolic heart failure or renal impairment: an observational study using propensity score matching
Schartum-Hansen, Hall; Løland, Kjetil Halvorsen; Svingen, Gard Frodahl Tveitevåg; Seifert, Reinhard; Pedersen, Eva Ringdal; Nordrehaug, Jan Erik; Bleie, Øyvind; Ebbing, Marta; Berge, Christ; Nilsen, Dennis W.T.; Nygård, Ottar (Peer reviewed; Journal article, 2015-06-01)Background Loop diuretics are widely used in patients with heart and renal failure, as well as to treat hypertension and peripheral edema. However, there are no randomized, controlled trials (RCT) evaluating their long ... -
β-blocker use and risk of all-cause mortality in patients with coronary heart disease: effect modification by serum vitamin A
Dhar, Indu; Svingen, Gard Frodahl Tveitevåg; Olsen, Thomas; Lysne, Vegard; Bjørnestad, Espen Øglænd; Ueland, Per Magne; Nygård, Ottar Kjell (Journal article; Peer reviewed, 2021)Aims Blockade of β-adrenoceptors reduces sympathetic nervous system activity and improves survival in patients with heart failure with reduced left ventricular ejection fraction (HFrEF); however, any improvement in ...
