value of abcd2-f in predicting cerebral ischemic attacks: three months follow-up after the primary attack

cerebrovascular attack (cva) and transient ischemic attack (tia) are major causes of emergency department visits around the globe. a significant number of these patients may experience repeat attacks if left untreated. several risk stratifying scoring systems have been developed in recent years to point out the high risk patients. abcd 2 is based on age, blood pressure, clinical status, diabetes mellitus, and duration of symptoms and is used commonly for this purpose. in this study, we were to enhance its sensitivity and specificity with the addition of another criterion namely atrial fibrillation and making abcd 2-f . a prospective study in two hospitals was performed and 138 patients diagnosed with tia/cva were enrolled. demographic, clinical, and paraclinical data of all patients were registered. all patients were followed for three months for any sign or symptom of a recurrent ischemic attack. recurrent ischemic attacks happened in 9.4% of the patients. none of the criteria of abcd 2-f was associated with higher chance of ischemic attacks. similarly, abcd 2-f was not different between patients with or without repeat cerebral ischemia. the addition of atrial fibrillation to abcd 2 did not enhance the accuracy of this scoring system to detect patients high risk for repeat cerebral ischemia. more studies in the future to improve sensitivity and specificity of this test are warranted.
