老年心房颤动患者发生缺血性脑卒中危险因素的研究

目的:了解老年心房颤动(A f)患者发生缺血性脑卒中的危险因素。方法:采用病例对照研究对372例老年慢性A f患者的临床资料,比较发生与不发生缺血性脑卒患者的病因、心室率、年龄、性别、心衰、并发高血压病、糖尿病、心房扩大与心脏瓣膜钙化的差异。结果:A f患者中,发生与不发生缺血性脑卒患者的病因、心室率、并发高血压病、糖尿病、心房扩大、心脏瓣膜钙化的发生情况差异有非常显著性(P均<0.01),但性别、年龄、心衰、A f类型的发生情况差异均无显著性(P均>0.05)。结论:心脏瓣膜病、心室率过缓、高血压病与糖尿病是A f并缺血性脑卒中的高危因素,老年人A f并发上术疾病者容易出现缺血性脑卒中,应予临床干预。

Risk factors for ischemic stroke in senile patients with auricular fibrillation

Objective: To investigate the risk factors for cerebral arterial thrombosis in gerontal patients with atrial fibrillation.Methods: Clinical data of 372 elderly patients with chronic auricular fibrillation were analyzed by case control study.The causative factors such as age,sex,etiological factor,ventricular rate,heart failure,hypertension,diabetes,atrial enlargement and cardiac valve calcification in patients with or without ischemic stroke were compared.Results: There were significant differences in etiological factor,ventricular rate,hypertension,diabetes,atrial enlargement and cardiac valve calcification between two groups(P<0.01),but the age,sex,heart failure and type of atrial fibrillation were unrelated to the development of ischemic stroke(P>0.05).WT6HZ]Conclusion: The valvular disease of the heart,bradycardia,hypertension and diabetes are the main risk factors for ischemic stroke,and these patients should receive the clinical intervention for prevention of ischemic stroke.
