Pocket-size Cardiovascular Ultrasound in Stroke

Status Completed

Clinical Trial Summary

Among patients admitted with cerebral ischemia (stroke and transitory ischemic attack (TIA)) it is important to reveal the underlying cause of the disease. In special it is important to reveal if carotid artery stenosis is present as such a finding will directly influence on treatment and follow-up. For the diagnosis of carotid artery stenosis due to atherosclerosis ultrasound examinations is the cornerstone, but computer tomography and magnetic resonance imaging may be better in some cases. Development of high quality pocket-sized ultrasound scanners has allowed for semi quantitatively bed-side assessment of the carotid arteries and the heart. The investigators aim to study the feasibility and reliability of bed-side assessment of the carotid arteries and the heart by pocket-sized ultrasound scanners and the clinical influence of this examination when performed by experienced users. The investigators hypothesize that a significant proportion of this patient population can be clarified bed-side with no need of further imaging procedures for the assessment of the carotid arteries and the heart.

Clinical Trial Description

Population: Approximately 100 patients admitted to the Department of Medicine, Levanger Hospital with history and findings suspicious of stroke/transitory ischemic attack (TIA). Informed consent mandatory. No exclusion criteria. Hypotheses: The carotid arteries and the heart can be assessed bed-side by pocket-size ultrasound scanners with high feasibility and reliability. Bed-side assessment of the carotid arteries and the heart by pocket-size ultrasound scanners may reduce the need for more advanced (higher cost) imaging procedures. Methods: Pocket-size imaging device from GE Ultrasound, commercial available. Approved for clinical use. High-end echocardiography and carotid Doppler ultrasound by high-end equipment (GE Vivid 9) and computer tomography and magnetic resonance imaging at the Department of Radiology, Levanger Hospital. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
