Answer

With passive reporting, the early risk of stroke after TIA is approximately 4% at 2 days, 8% at 30 days, and 9% at 90 days. [14] When patients with TIA are followed prospectively, however, the incidence of stroke is as high as 11% at 7 days. [3] The probability of stroke in the 5 years following a TIA is reported to be 24-29%. In addition, patients with TIAs or stroke have an increased risk of coronary artery disease. [15]
