Survival status and analysis of related factors of mortality among elderly patients with first-ever stroke / 重庆医学

ABSTRACT

Objective To describe the survival status and to analyze the related factors of mortality among elderly patients with first-ever stroke.Methods Totally 1 96 elderly patients with first-ever stroke from January 2010 to January 2014 were enroll for the study.The survival status of all cases was attained through follow-up,and the deadline of follow-up was July 30,2014.The deceased patients because of stroke were divided into death group while the others were divided into survival group.Univariate com-parison and multivariate Logistic regression analysis were performed to screen out the related factors of death.Results The median follow-up time was 41 months,and 14 cases were lost to follow-up.The survival rate 28 d,1 year and 3 years after the onset were 73.47%,66.81% and 58.89%.Age,complication,Glasgow score,NIHSS score and blood WBC were the independent influence fac-tors of death (P <0.05).Conclusion The death among elderly patients with first-ever stroke are more concentrated in 28 d after the onset.Advanced age,complications,decrease of Glasgow score,increase of NIHSS score and blood WBC could increase the death risk.
