为探讨缺血性脑卒中患者早期复发的临床特点和危险因素，对复发的缺血性卒中患者进行了临床分析和病例－对照研究。结果６３７例完全性缺血性卒中，有２４例复发，其总复发率为３．８％（２４／６３７），其中脑血栓的复发率为３．４％（２０／５９１），脑栓塞为８．７％（４／４６）。大部分病例（７１％，１７／２４）复发发生在原患侧，且多为同卒中类型复发（８３％，２０／２４）。经ＭｃＮｅｍａｒ卡方检验发现高血压史、有ＴＩＡ或脑梗塞史、糖尿病等因素与对照相比有显著性差异，而缺血性心脏病、房颤、入院时高血糖、血脂增高和吸烟与复发无显著相关。认为缺血性脑卒中患者早期复发多为同卒中类型、同部位的复发，高血压、有ＴＩＡ或脑梗塞史、糖尿病可能为卒中早期复发的危险因素。
To investigate the clinical features and risk factors of early relapse in patients with ischemic stroke, clinical analysis and case-control studies were performed on patients with recurrent ischemic stroke. Results 637 cases of complete ischemic stroke, 24 cases of recurrence, the total recurrence rate was 3.8% (24/637), of which the recurrence rate of cerebral thrombosis was 3.4% (20/591), cerebral embolism 8.7% (4/46). The majority of cases (71%, 17/24) had recurrences on the original ipsilateral side and were mostly symptomatic with recurrent stroke (83%, 20/24). The McNemar Chi-square test found that history of hypertension, history of TIA or cerebral infarction, diabetes and other factors were significantly different compared with the control, and ischemic heart disease, atrial fibrillation, admission, hyperglycemia, elevated blood lipids and smoking and relapse No significant correlation. It is believed that the early recurrence of ischemic stroke is mostly the same type of stroke, recurrence of the same site, hypertension, history of TIA or cerebral infarction, and diabetes mellitus may be the risk factors for the early recurrence of stroke.
