Adding stress biomarkers to high-sensitivity cardiac troponin for rapid non-ST-elevation myocardial infarction rule-out protocols
Restan, Ingar Ziad; Sanchez, Ana Yufera; Steiro, Ole-Thomas; Lopez-Ayala, Pedro; Tjora, Hilde Lunde; Langørgen, Jørund; Omland, Torbjørn; Boeddinghaus, Jasper; Nestelberger, Thomas; Koechlin, Luca; Collinson, Paul; Bjørneklett, Rune Oskar; Vikenes, Kjell; Strand, Heidi; Skadberg, Øyvind; Mjelva, Øistein; Larsen, Alf Inge; Vernon, Bonarjee; Mueller, Christian; Aakre, Kristin Moberg (Journal article; Peer reviewed, 2022)Aims This study tested the hypothesis that combining stress-induced biomarkers (copeptin or glucose) with high-sensitivity cardiac troponin (hs-cTn) increases diagnostic accuracy for non-ST-elevation myocardial infarction ... -
Borderline values of troponin-T and high sensitivityC-reactive protein did not predict 2-year mortality inTnTpositive chest-pain patients, whereas brain natriureticpeptide did
Nilsen, Dennis W.T.; Mjelva, Øistein; Leon de la Fuente, Ricardo; Næsgaard, Patrycja; Pønitz, Volker; Andersen, Trygve Brugger; Grundt, Heidi; Staines, Harry; Nilsen, Stein Tore (Peer reviewed; Journal article, 2015-04-08)Background: Troponin-T (TnT), high-sensitive C-reactive protein (hsCRP), and Brain Natriuretic Peptide (BNP) have been shown to be independent prognostic indicators of total and cardiac death during short- and long-term ... -
Diagnostic Performance of Novel Troponin Algorithms for the Rule-Out of Non-ST-Elevation Acute Coronary Syndrome
Tjora, Hilde Lunde; Steiro, Ole-Thomas; Langørgen, Jørund; Bjørneklett, Rune Oskar; Skadberg, Øyvind; Bonarjee, Vernon V S; Mjelva, Øistein; Collinson, Paul; Omland, Torbjørn; Vikenes, Kjell; Aakre, Kristin Moberg (Journal article; Peer reviewed, 2022)Background The European Society of Cardiology (ESC) rule-out algorithms use cutoffs optimized for exclusion of non-ST elevation myocardial infarction (NSTEMI). We investigated these and several novel algorithms for the ... -
Growth Differentiation Factor 15: A Prognostic Marker in Patients with Acute Chest Pain without Acute Myocardial Infarction
Myrmel, Gard Mikael Saele; Steiro, Ole-Thomas; Tjora, Hilde Lunde; Langørgen, Jørund; Bjørneklett, Rune Oskar; Skadberg, Øyvind; Bonarjee, Vernon V S; Mjelva, Øistein; Pedersen, Eva Ringdal; Vikenes, Kjell; Omland, Torbjørn; Aakre, Kristin Moberg (Journal article; Peer reviewed, 2023)Background Acute chest pain is associated with an increased risk of death and cardiovascular events even when acute myocardial infarction (AMI) has been excluded. Growth differentiation factor-15 (GDF-15) is a strong ... -
Predictors of long-term symptom burden and quality of life in patients hospitalised with chest pain: a prospective observational study
Saeed, Nasir; Norekvål, Tone Merete; Steiro, Ole-Thomas; Tjora, Hilde Lunde; Langørgen, Jørund; Bjørneklett, Rune Oskar; Skadberg, Øyvind; Bonarjee, Vernon V S; Mjelva, Øistein; Omland, Torbjørn; Vikenes, Kjell; Aakre, Kristin Moberg (Journal article; Peer reviewed, 2022)Objective: To describe the magnitude and predictors of symptom burden (SB) and quality of life (QoL) 3 months after hospital admission for acute chest pain. Design: Prospective observational study. Setting: Single ... -
Prognostic significance of chronic myocardial injury diagnosed by three different cardiac troponin assays in patients admitted with suspected acute coronary syndrome
Steiro, Ole-Thomas; Langørgen, Jørund; Tjora, Hilde Lunde; Bjørneklett, Rune Oskar; Skadberg, Øyvind; Bonarjee, Vernon V S; Mjelva, Øistein; Steinsvik, Trude; Lindahl, Bertil; Omland, Torbjørn; Aakre, Kristin Moberg; Vikenes, Kjell (Journal article; Peer reviewed, 2023)Objectives Chronic myocardial injury (CMI) is defined as stable concentrations of cardiac troponin T or I (cTnT or cTnI) above the assay-specific 99th percentile upper reference limit (URL) and signals poor outcome. The ...
