Previous studies conducted between 1997 and 2003 estimated that the risk of stroke or an acute coronary syndrome was 12 to 20% during the first 3 months after a transient ischemic attack (TIA) or minor stroke.1,2Since then, there have been major changes in the management of TIA, including urgent management in specialized units, implementation of immediate investigations, and rapid treatment with antithrombotic agents and other stroke-prevention strategies.1-4 Given these changes, the current prognosis of patients who have had a TIA and the role of risk-scoring systems in patients receiving urgent care are unclear.5-11 Current guidelines recommend triage of patients on the basis of the risk of stroke as assessed by the ABCD2 (age, blood pressure, clinical findings, duration of symptoms, and presence or absence of diabetes) score. Scores range from 0 to 7, with higher scores indicating a greater risk of stroke; an age of 60 years or older, a blood-pressure level of 140/90 mm Hg or higher, a clinical finding of unilateral weakness or speech impairment, a duration of symptoms of 10 to 59 minutes, and diabetes are each assigned 1 point, and a duration of symptoms of 60 minutes or more is assigned 2 points. Urgent care of patients with TIA within 24 hours after symptom onset is recommended when the ABCD2 score is 4 or more.12,13However, ABCD2 scores of 4 or more do not identify all patients needing immediate treatment.14-16The widespread introduction of emergency services for patients who have had a TIA or minor stroke in most developed health care systems makes it important to reassess prognosis and risk stratification.
The TIAregistry.org project was designed to describe the contemporary profile, etiologic factors, and short-term (1-year) and long-term (5-year) outcomes in patients with a TIA or minor ischemic stroke and to refine risk assessment in the context of modern stroke prevention and management. Here we report 1-year follow-up data
