Patients
suffering from a transient ischemic attack (TIA) are at high risk of
recurrent TIAs, particularly within the first 4 weeks. The risk of recurrent
thromboembolic events gradually decreases afterwards. The United Kingdom
National Stroke Strategy warrants emergency management of high-risk patients.
High resolution magnetic resonance can assist us to identify high-risk
plaques and assess the morphological and biomechanical changes within plaques
using computational simulations, thereby refining our risk stratification
criteria for management of high-risk patients. In this study we assess the
impact of age of plaque haemorrhage on plaque stress in patients suffering
from TIAs.
