Abstract INTRODUCTION: Transient ischemic attacks (TIA) are warnings of future stroke.There is no difference in risk factors, pathophysiology and prevention between 355 maybelline fit me TIA and brain infarction.methods: Consecutive patients with brain infarction admitted to Ghaem Hospital, Mashhad, Northeastern Iran, were enrolled in a prospective study during 2006.
Diagnosis of ischemic stroke was established by a neurologist who also obtained history of TIA and vascular risk factors.All of the stroke patients underwent a standard battery of diagnostic investigations and etiology of ischemic stroke was determined by the Practical Iranian Criteria classification.Fisher’s exact test was used for statistical analysis.
results: 348 stroke patients (186 women, 162 men) were studied.History of TIA was present in 42 patients (29 women, 13 men), i.e.
12% of the stroke patients.TIA was more common in women (df=1, P=0.02).
The frequency of hypertension, diabetes and ipsilateral carotid stenosis was not significantly different between patients with history of TIA and other stroke patients (P=0.87, P=0.64 and P=0.
61, respectively).Hyper-cholesterolemia and smoking were significantly more frequent in stroke patients with history of TIA (P=0.011 and P=0.
014, respectively).The frequency of TIA was not significantly different among patients with lacunar, versus large vessel territory infarcts (df=1, P=0.84).
There was no significant difference in the frequency of various stroke etiologies in patients with and without history of TIA (df=4, P=0.61).CONCLUSIONS: Stroke patients with history of TIA have vascular risk factors footjoy weste herren similar to other stroke patients.
A positive history of TIA does not affirm any specific etiology of ischemic stroke. Keywords: Risk factors, etiology, transient ischemic attacks.
