Can the cardiovascular family history reported by our patients be trusted? The Norwegian Stroke in the Young Study
Øygarden, Halvor; Fromm, Annette; Sand, Kristin Modalsli; Eide, Geir Egil; Thomassen, Lars; Næss, Halvor; Waje-Andreassen, Ulrike (Peer reviewed; Journal article, 2016-01)Background and purpose: Family history (FH) is used as a marker for inherited risk. Using FH for this purpose requires the FH to reflect true disease in the family. The aim was to analyse the concordance between young and ... -
Does a history of migraine affect the rate of thrombolysis in young stroke patients?
Øygarden, Halvor; Kvistad, Christopher Elnan; Thomassen, Lars; Waje-Andreassen, Ulrike; Næss, Halvor (Peer reviewed; Journal article, 2013)Background. Migraine is prevalent in young patients and a frequent stroke mimic. To distinguish stroke mimics from true stroke can be difficult, and there is a possibility of misdiagnosing a stroke as a migrainous attack ... -
Early vascular aging in young and middle-aged ischemic stroke patients: The Norwegian stroke in the young study
Saeed, Sahrai; Waje-Andreassen, Ulrike; Fromm, Annette; Øygarden, Halvor; Kokorina, Marina Victorovna; Næss, Halvor; Gerdts, Eva (Peer reviewed; Journal article, 2014-11-18)Background: Ischemic stroke survivors have high risk of cardiovascular morbidity and mortality even at young age, suggesting that early arterial aging is common among such patients. Methods: We measured aortic stiffness ... -
Family history in young and middle-aged acute ischemic stroke patients. The Norwegian Stroke in the Young Study
Øygarden, Halvor (Doctoral thesis, 2016-04-08)Cardiovascular disease (CVD), including stroke, coronary heart disease (CHD) and peripheral artery disease, is the leading cause of death and disability in the western world. CVD is influenced by genetic and lifestyle ... -
A family history of stroke is associated with increased intima-media thickness in young ischemic Stroke - The norwegian stroke in the young study (NOR-SYS)
Øygarden, Halvor; Fromm, Annette; Sand, Kristin Modalsli; Kvistad, Christopher Elnan; Eide, Geir Egil; Thomassen, Lars; Næss, Halvor; Waje-Andreassen, Ulrike (Peer reviewed; Journal article, 2016-08-09)Background and Purpose: Positive family history (FH+) of cardiovascular disease (CVD) is a risk factor for own CVD. We aimed to analyze the effect of different types of FH (stroke, coronary heart disease (CHD), peripheral ... -
NOR-SASS (Norwegian Sonothrombolysis in Acute Stroke Study): Randomized controlled contrast-enhanced sonothrombolysis in an unselected acute ischemic stroke population
Nacu, Aliona; Kvistad, Christopher Elnan; Næss, Halvor; Øygarden, Halvor; Logallo, Nicola; Assmus, Jörg; Waje-Andreassen, Ulrike; Kurz, Kathinka Dæhli; Neckelmann, Gesche F; Thomassen, Lars (Peer reviewed; Journal article, 2016-02)Background and Purpose—The NOR-SASS (Norwegian Sonothrombolysis in Acute Stroke Study) aimed to assess effect and safety of contrast-enhanced ultrasound treatment in an unselected acute ischemic stroke population. ... -
Prevalence of atherosclerosis and association with 5-year outcome: The Norwegian Stroke in the Young Study
Nawaz, Beenish; Fromm, Annette; Øygarden, Halvor; Eide, Geir E; Saeed, Sahrai; Meijer, Rudy; Bots, Michiel L; Sand, Kristin M; Thomassen, Lars; Næss, Halvor; Waje-Andreassen, Ulrike (Journal article; Peer reviewed, 2021)Objectives: We studied the prevalence of atherosclerosis among ischaemic stroke patients ≤60 years and controls at the time of the index stroke, and its association with occurrence of new cardiovascular events (CVEs) and ... -
Stroke patients’ knowledge about cardiovascular family history – the Norwegian Stroke in the Young Study (NOR-SYS).
Øygarden, Halvor; Fromm, Annette; Sand, Kristin Modalsli; Eide, Geir Egil; Thomassen, Lars; Næss, Halvor; Waje-Andreassen, Ulrike (Peer reviewed; Journal article, 2015-03-12)Background: Family history (FH) is a risk factor for cardiovascular disease, especially coronary artery disease (CAD). The impact on risk of stroke is less clear. This study investigated young and middle-aged ischemic ... -
Vascular risk factors and staging of atherosclerosis in patients and controls: The Norwegian Stroke in the Young Study
Nawaz, Beenish; Fromm, Annette; Øygarden, Halvor; Eide, Geir Egil; Saeed, Sahrai; Meijer, Rudy; Bots, Michiel L; Sand, Kristin Modalsli; Thomassen, Lars; Næss, Halvor; Waje-Andreassen, Ulrike (Journal article; Peer reviewed, 2022)Objectives: We studied the prevalence of vascular risk factors (RFs) among 385 ischaemic stroke patients ⩽60 years and 260 controls, and their association with atherosclerosis in seven vascular areas.
