Transient Ischemic Attack: Complications

The following are the major diseases or complications that may be contributed to by a transient ischemic attack (TIA):

Cardiovascular system (I00-I99)

  • Apoplexy (risk of stroke remains elevated over the five years).

Prognostic factors

ABCD2 score

The ABCD2 score is a prognostic scoring system that can be used to estimate stroke risk after transient ischemic attacks (TIAs).

Risk factor Criterion Points
A = Age
  • <60 years
  • ≥ 60 years
 01
B = blood pressure, initial
  • Normal
  • > 140 mmHg (syst.) or > 90 mmHg (diast.)
 01
C = Clinical features (symptoms)
  • Other complaints
  • Speech disorder without unilateral paresis (unilateral incomplete paralysis).
  • Unilateral paresis
 012
D = duration of symptoms
  • <10 min
  • 10-59 min
  • ≥ 60 min
 012
D = diabetes mellitus
  • Not existing
  • Existing

Assessment

The risk of developing another stroke within 2 days of a TIA is determined as follows:

Percent risk for apoplexy

Points 2 days 7 days 90 days
0-3 1,0 1,2 3,1
4-5 4,1 5,9 9,8
6-7 8,1 12 18

The ABCD3 score was supplemented by cerebral imaging results, particularly magnetic resonance imaging (MRI). This score best identified the 7-day apoplexy risk. The prediction probability increased by 33% compared with the ABCD2-I score.
