Blood pressure and cerebral artery pulsatility in small vessel disease-related TIA and ischaemic stroke 

Stroke is the second leading cause of death worldwide, and high blood pressure (BP) is the most important treatable factor that increases a person’s risk of suffering a stroke. Stiffness of the blood vessels supplying the brain, possibly due to long-standing raised BP, is also likely to be a factor that increases stroke risk. Such increased stiffness results in the blood flow through these vessels being more pulsatile than usual, and this pulsatility can be assessed by an ultrasound scan. This research is focused on assessing the relationship between this pulsatility and the risk of stroke in patients who have already had a stroke or “mini-stroke” in the past, and in particular to see if this relationship can be explained by raised BP alone. The Oxford Vascular Study (OXVASC) recruits all patients with stroke or “mini-stroke” from a single population, and shortly after such an event, participants undergo multiple investigations including an ultrasound assessment of pulsatility. They are provided with a home monitor that sends results wirelessly to our unit and facilitates detailed measurement of BP, and are followed up at regular intervals to assess for possible recurrent events. The OXVASC study represents an ideal opportunity to investigate the risk of stroke associated with BP and arterial stiffness, and this will allow us to better assess patients’ risk and identify possible new treatments for reducing arterial stiffness and stroke risk.
