目的分析老年深静脉血栓形成患者发生肺栓塞与合并症的关系。方法收集某院2009年-2014年所有出院患者诊断(包含其它诊断)中包含深静脉血栓形成的老年患者资料652例,以是否发生肺栓塞(是/否)为因变量,以性别、年龄及各种合并症为自变量,进行多重logistic回归分析。结果合并心脏病(χ~2=10.227,P<0.001)、合并肺炎(χ~2=10.456,P<0.001)、合并肺部感染(χ~2=4.634,P=0.031)、合并贫血(χ~2=5.720,P=0.017)对老年深静脉血栓形成患者发生肺栓塞的影响具有统计学意义。性别、年龄及其它合并症的影响均无统计学意义(P>0.05)。结论合并心脏病、肺炎、肺部感染是老年深静脉血栓形成患者发生肺栓塞的危险因素。因此,对于这类患者,应密切监护,做到早诊断、早治疗,以降低肺栓塞患者的病死率。
Objective To analyze the relationship between pulmonary embolism and comorbidity in elderly patients with deep venous thrombosis. Methods A total of 652 elderly patients with deep vein thrombosis (including other diagnoses) were enrolled from 2009 to 2014 in a hospital. The incidence of pulmonary embolism (yes / no) was used as the dependent variable, and sex, age and Various complications as independent variables, multiple logistic regression analysis. Results The patients with combined heart disease (χ ~ 2 = 10.227, P <0.001) had pneumonia (χ ~ 2 = 10.456, P <0.001) ~ 2 = 5.720, P = 0.017) had significant effect on pulmonary embolism in elderly patients with deep venous thrombosis. Gender, age and other complications had no significant effect (P> 0.05). Conclusion Concurrent heart disease, pneumonia and pulmonary infection are the risk factors of pulmonary embolism in elderly patients with deep venous thrombosis. Therefore, for such patients, should be closely monitored, so early diagnosis and early treatment to reduce the mortality of patients with pulmonary embolism.
