The traditional view is that TIA is a benign, reversible cerebral ischemic syndrome, and the risk of recurrence is lower than that of cerebral infarction. However, studies have shown that patients with TIA have a high risk of developing stroke early^[7]Patients with TIA had a stroke risk of 4% to 10% within 7 days and 10% to 20% (mean 11%) at 90 days^{[8,9,10,11,12,13]}。 However, the risk of recurrence within 90 days of acute stroke is 2% to 7%. In addition, patients with TIA are not only prone to cerebral infarction, but also prone to myocardial infarction and sudden death. The overall risk of TIA recurrence, myocardial infarction, and death events within 90 days is up to 25%. Therefore, TIA is a serious stroke warning event that needs urgent intervention. It is the most important emergency, and it is also the best time for secondary prevention, which must be paid attention to. At present, the field of diagnosis and treatment of TIA in China is underestimated and misjudged seriously; The hospitalization rate is only about 6%, far lower than the proportion of about 30% in developed countries.
