Clinical features of the elderly patients over 80 years with cute cerebral infarction / 中国综合临床

ABSTRACT

Objective To investigate the risk factors,severity and infarct site features and clinical characteristics of the elderly patients over 80 years with cute cerebral infarction.Methods One hundred and sixty-two patients with acute cerebral infarction in Red Cross Hospital of Guangzhou,The Forth Affiliated Hospital of Medical College of Jinan University from January 2012 to May 2015 were enrolled and randomly divided into the elderly patients (≥ 80 years old) and the middle aged patients (＜ 60 years old).The risk factors,national institutes of health stroke scale (NIHSS) scores and Oxfordshire community stroke project (OCSP) criteria were compared between the two groups.Results Coronary artery disease,atrial fibrillation and NIHSS in the elderly patients (25％ (22/88),13.6％ (12/88),7.74 ± 4.986) were significantly higher than those of the middle aged group (12.2％ (9/47),4.1％ (3/74),5.04± 4.305),and the differences were significant (x2 =4.281,4.393,t =-3.649;P＜ 0.05 or P＜ 0.001).The logistic regression analysis finally showed that smoking,hyperlipemia,NIHSS scores and gender(male) were the independent risk factors(OR=3.851,3.609,1.100 and 2.670;P＜0.05).There were more LACI patients in the elderly group than he middle aged group ((40.9％,36/88) vs.(60.8％,45/74),x2 =6.369,P ＜ 0.05).Conclusion Compare to the middle aged patients,occurrence of the elderly patients with acute cerebral infarction is more severe,and the clinical features and risk factors have its particularity.Secondary prevention strategy should be emphasized on the control of different risk factors based on the patients' age.
