Voorspelbaar risico op herseninfarct na een 'transient ischaemic attack' (TIA)

– To date most studies that have addressed prognostic factors in patients who have had a transient ischaemic attack (TIA) have determined the risk of cerebral infarction during the first 3 years following TIA. Two recent studies have investigated the very long-term and very short-term risks. The long-term study found that the risk unexpectedly increased after 3 years. The short-term study found the very early risk of cerebral infarct (< 7 days) to be substantial at 10. The proposed ABCD score enables the physician to easily identify patients at particularly high risk: (A) 1 point for age C 60 years, (B) 1 for systolic blood pressure > 140 mmHg and/or diastolic pressure > 90 mmHg, (C) 2 points for unilateral weakness, 1 for speech disturbance without weakness, (D) 2 points for an attack lasting C 1 h and 1 point for an attack lasting 10-59 min. A patient with a total score of 5 has a risk of 12.1 of developing a cerebral infarct within 7 days. In a patient with a score of 6 this risk is 31.4.
