Calculating the 30-day survival in acute myocardial infarction: should we use the treatment chain or the hospital catchment model?
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-01-12)<p><i>Introduction</i> Acute myocardial infarction (AMI) is a potentially deadly disease and significant efforts have been concentrated on improving hospital performance. A 30-day survival rate has become a key quality of care indicator. In Northern Norway, some patients undergoing AMI are directly transferred to the Regional Cardiac Intervention Center at the University Hospital of North Norway ... -
Direct angiography demonstrates equal 8-12 years patency rates of radial artery and saphenous vein grafts
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-06-30)Objectives: The benefits of coronary artery bypass surgery depend on lasting graft patency. To aid rational graft selection, the relative long-term merits of radial artery and saphenous vein grafts need to be determined by a gold standard method and with minimal clinically driven selection bias. Methods: The patency rates of various conduits were determined by direct angiography in 76 patients from ... -
Low pain tolerance is associated with coronary angiography, coronary artery disease, and mortality: The TROMSO study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-11-03)BACKGROUND: The initial presentation to coronary angiography and extent of coronary artery disease (CAD) vary greatly among patients, from ischemia with no obstructive CAD to myocardial infarction with 3-vessel disease. Pain tolerance has been suggested as a potential mechanism for the variation in presentation of CAD. We aimed to investigate the association between pain tolerance, coronary ... -
Outcomes after coronary angiography for unstable angina compared to stable angina, myocardial infarction and an asymptomatic general population
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-07-31)Background: The outcomes of real-world unstable angina (UA) in the high-sensitivity troponin era are unclear. We aimed to investigate the outcomes of UA referred to coronary angiography compared to stable angina (SA), nonST-segment elevation myocardial infarction (NSTEMI), STEMI and a general population.<p> <p>Methods: We included the 9,694 patients with no prior coronary artery disease (CAD) ... -
Pre-test characteristics of unstable angina patients with obstructive coronary artery disease confirmed by coronary angiography
(Master thesis; Mastergradsoppgave, 2017-10-31)Objective As the mortality and rate of obstructive coronary artery disease (CAD) is low in patients with unstable angina (UA), better pre-test selection criteria for acute coronary angiography (CAG) is warranted. We aimed to validate the current guidelines against other clinical variables as predictors of obstructive CAD in UA patients referred for acute CAG. Methods From 2005 to 2012, all CAGs ... -
Pre-test characteristics of unstable angina patients with obstructive coronary artery disease confirmed by coronary angiography
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-11-01)<p><i>Objective</i>: Patients referred for acute coronary angiography (CAG) with unstable angina (UA) have low mortality and low rate of obstructive coronary artery disease (CAD). Better pre-test selection criteria are warranted. We aimed to assess the current guidelines against other clinical variables as predictors of obstructive CAD in patients with UA referred for acute CAG.</p> <p><i>Methods</i>: ... -
Randomised comparison of provisional side branch stenting versus a two-stent strategy for treatment of true coronary bifurcation lesions involving a large side branch: The Nordic-Baltic Bifurcation Study IV
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-01-19)<p><i>Background - </i>It is still uncertain whether coronary bifurcations with lesions involving a large side branch (SB) should be treated by stenting the main vessel and provisional stenting of the SB (simple) or by routine two-stent techniques (complex). We aimed to compare clinical outcome after treatment of lesions in large bifurcations by simple or complex stent implantation. <p><i>Methods ... -

The risk factors for radial artery and saphenous vein graft occlusion are different
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-06-02)Objectives. To determine risk factors for radial artery and saphenous vein graft occlusion during long-term follow-up after coronary artery bypass grafting (CABG). Methods: From a cohort of 119 patients who had received a radial artery graft, 76 – of whom 55 also had at least one saphenous vein graft – underwent a preplanned direct angiography and anthropometric, biochemical, and endothelial ... -
Treatment of acute myocardial infarction in the sub-arctic region of Norway. Do we offer an equal quality of care?
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-10-26)Patients, relatives, healthcare workers and administrators are concerned about the quality of care offered. We aimed to explore the treatment of acute myocatrdial infarction (AMI) in Northern Norway, compare it with the national figures, and document whether there is an equal quality of care or not. The retrospective study included data on patients' treatment for AMI. The following sources were ...
