Morphology of Advanced Symptomatic Cerebral Plaques With High Embolic Potential

The study is to attain early recognition of the unstable plaques which have an imminent embolic risk in patients with intracranial atherosclerotic disease (IAD).

Morphologic Evolution and Remodeling of Intracranial Atherosclerosis: A Longitudinal Study by 3D-rotational Angiography

This study is to elucidate the morphologic evolution and remodeling of ICAD under stringent control of cardiovascular risk factors.

A Study of Cerebral Perfusion With tDCS in Chronic Hypoperfusion

This study is being done to examine whether transcranial direct current stimulation (tDCS) will increase cerebral blood flow which may provide a clinical benefit such as improving cognitive impairment.

Digital Secondary Prevention After Atherosclerotic Cardiovascular Disease

Atherosclerotic cardiovascular disease (ASCVD) remains a leading cause of morbidity and mortality worldwide and in Norway. Approximately 50% of the patients admitted to hospitals with an acute ASCVD event has had a previous event. The high number of patients being readmitted to hospitals with new ASCVD events is to a large degree explained by poor control of established risk factors such as high LDL-cholesterol, high blood pressure (BP), diabetes, obesity, smoking, and lack of physical activity, as well as poor adherence to evidence-based medication. This pragmatic, open-label proof-of-concept study conducted at three secondary care hospitals will randomly assign patients hospitalized with an ASCVD event to either: (i) brief advice, tailored discharge information to general practitioners, and a nurse-led outpatient visit (control), or (ii) the same interventions as (i) plus a single in-hospital motivational counselling session and access to a digital platform for a 6 months period with patient information/videos and an individualized treatment plan and follow-up plan. The primary end point will be between-group differences in the proportion who report having attended follow-up visits in primary (primary care physicians and community-based healthy life centres) and specialist (cardiac rehabilitation programs, hospital outpatient visits) healthcare after 8 weeks and 6 months follow-up. Secondary end points will be change in the SMART2 risk score and cardiovascular risk factors between baseline and 6 and 12 months follow-up. Exploratory end points will be changes in adherence to cardiovascular drugs, self-care behaviour, health literacy, patient activation, and quality of life.

Balloon-expandable DES for ICAS Registry Study (BDES-ICAS Registry)

To study the clinical outcomes after implantation of balloon-expandable drug-eluting stents in patients with symptomatic intracranial atherosclerotic stenosis in prevention of composite event of any stroke and death within 30 days and ischemic stroke in the territories of the responsible artery from 31 days to 1-year.
