Abstract: Objective To study the relation between history of ipsilatral transient ischemic attack(TIA) and a subsequent cerebral infarction(CI).Methods A total of 568 patients(pts) with first CI were divided into two groups based on history of ipsilatral TIA: TIA group(n=108,pts with TIAs) and non-TIA group(n=460,pts without ipsilatral TIAs).TIA group was divided into 4 subgroups base on duration of attack: subgroup 1(attack duration <10 min),subgroup 2(attack duration 10 min~30 min);subgroup 3(attack duration 31 min~60 min) and subgroup 4(attack time <10 min).The relationship between neuroprotective effects of TIAs and the duration of TIA was analyzed.The score of neurological impairment was rated according to the score standards of CSS and ADL at admittance.Results There was high rate(83%) of light neurological impairment and I prognosis was 76% in subgroup 2.Compared with Group without TIAs,there was significant difference(P<0.05).There was severe neurological impairment in subgroup 3,subgroup 4 and the pts in group without TIAs.The grade I prognosis in the subgroup 1,subgroup 3 and subgroup 4 was 64%,61% and 61%,respectively(P>0.05).Conclusion The neuroprotective effect of TIAs was related to duration of TIA.
