目的分析老年脑梗死患者院内死亡的危险因素。方法收集某院2008年-201 1年所有出院患者中主要诊断为脑梗死的老年患者资料1545例,以出院情况(生存/死亡)为因变量,以性别、年龄、出院年份及各种合并症为自变量,进行多重logistic回归分析。结果合并肺部感染(χ~2=62.527,P<0.0001)、合并肺炎(χ~2=59.047,P<0.0001)、合并急性心肌梗死(χ~2=21.529,P<0.0001)、合并心房纤颤(χ~2=8.814,P=0.003)、合并慢性风湿性心脏病(χ~2=6.381,P=0.012)对老年脑梗死患者院内死亡的影响具有统计学意义。性别、年龄、出院年份及其它合并症的影响均无统计学意义(P>0.05)。结论合并肺部感染、肺炎、急性心肌梗死、心房纤颤以及慢性风湿性心脏病是老年脑梗死患者院内死亡的危险因素。因此,对于这类患者,应密切监护,做到早诊断、早治疗,以降低脑梗死患者的院内死亡率。
Objective To analyze the risk factors of nosocomial death in elderly patients with cerebral infarction. Methods A total of 1545 elderly patients with major cerebral infarction who were discharged from hospital were collected from 2008 to 2011 in a hospital. The discharge (survival / death) was taken as the dependent variable, and the gender, age, year of discharge and various complications As independent variables, multiple logistic regression analysis. Results Pulmonary infection (χ ~ 2 = 62.527, P <0.0001) and pneumonia (χ ~ 2 = 59.047, P <0.0001) were associated with acute myocardial infarction (χ ~ 2 = 21.529, P <0.0001) (Χ ~ 2 = 8.814, P = 0.003), and chronic rheumatic heart disease (χ ~ 2 = 6.381, P = 0.012) had statistically significant effect on in-hospital mortality in elderly patients with cerebral infarction. Gender, age, year of discharge and other complications had no significant effect (P> 0.05). Conclusions Combined pulmonary infection, pneumonia, acute myocardial infarction, atrial fibrillation and chronic rheumatic heart disease are risk factors for nosocomial death in elderly patients with cerebral infarction. Therefore, for such patients, should be closely monitored, so early diagnosis and early treatment to reduce in-hospital mortality in patients with cerebral infarction.
