Abstract

To evaluate the risk factors which are related to recurrence of ischemic stroke, we selected subjects who were admitted to YNUH due to recurrent stroke and compared their risk factors with non-recurred group- who suffered from single ischemic stroke. In the subjects, 55 of them are men and 22 were women and in the non-recurred groups, 84 of them were men and 40 were women, Subject's age ranged from 29 to 86 years (Mean 62.5years), and non-recurred group's age ranged from 27 to 90 years (Mean 60.7years), Peak incidence of ischemic stroke is in the 7th decade in both groups. Age and sex are not statistically significant for recurrence of ischemic stroke. The patient's history of diabetes mellitus, myocardial infarction, atrial fibrillation, transient attack and type or site of ischemic stroke had no significant effect statistically on the recurrent ischemic stroke. However, when the patient had previous history of hypertension or systolic blood pressure more than 160 mmHg and diastolic more than 95mmHg, there was substantial difference (P<0.05) between the two group in the recurrence of ischemic stroke. According to the above results, hypertension is most likely significant risk factor of the recurrence of ischemic stroke within 2 yers after initial one. Therefore, adequate treatment of the hypertension is important for the prevention of ischemic stroke. Further study is required for searching other risk factors.
