Abstract:
Objective To examine the recurrent ischemic stroke(RIS)in hospitalized patients predicted by Essen Stroke Risk Score(ESRS)and investigate the effect of intensive antiplatelet therapy in patients with high risk of RIS. Methods Retrospective analysis of patients with acute noncardioembolic ischemic stroke consecutively admitted to Peking Union Medical College Hospital(PUMCH)during 2001-2008. All 1008 patients were included in this study, 377 hospitalized in 2001-2002, 315 in 2005 and 316 in 2008. High risk of RIS was defined as ESRS ≥3. The average ESRS score in three groups and percentage of patients with high risk of RIS in each group were calculated. Risk of RIS was evaluated by comparing the average ESRS score in these three groups. Patients with high risk and taking clopidogrel treatment were also evaluated. Results Average ESRS score was 2. 67 ± 1.47,3.55 ± 1.40 and 3.93 ± 1.48(F= 150. 85,P=0.000)in groups of patients hospitalized in 2001-2002, 2005 and 2008 respectively. A significant difference was shown in percentage of high risk patients with ESRS ≥3 in three groups: as 51.64% in 2001-2002,77. 19% in 2005 and 85. 45% in 2008(X2=98.30,P=0. 000),showing a trend of increasing risk of RIS. Except for patients age, rates of having the risk factors in patients increased significantly, including hypertension, diabetes, myocardial infarction, myocardial diseases, smoking,vascular disease and stroke history. Clopidogrel usage has been increasing to 25.63% in 2008, but was far behind high ratio of high risk RIS patients(85.45%). Conclusions This retrospective study showd an increasing trend in RIS risk during 2001-2008. Identifying high risk patients and applying intensified antiplatelet therapy might play an important role in reducing the risk of RIS.
