Given the growing focus on early recognition of stroke, short-term stroke rates following transient ischemic attacks (TIAs) are of interest. In this study from Oxfordshire, U.K., researchers describe early outcomes in 1000 consecutive patients who experienced TIAs. By subtype, initial TIAs were cardioembolic in 16% of patients, large-artery arteriosclerotic in 14%, small-vessel in 11%, undetermined in 47%, and multiple or other in 13%.
During the first 7 days after TIAs, 25% of patients suffered first recurrent cerebrovascular events (TIA in 17% and stroke in 9%). None of the TIA subtypes were significantly more likely than others to be associated with recurrent TIA. However, the small-vessel disease subtype was significantly more likely tha…
