Analysis Of Clinical Risk Factors Of Bacterial Pneumonia Associated With Pulmonary Embolism

Objective(s):Our study aim is to analyze the Yan'an Hospital of Kunming Medical University patients with characteristics of bacterial pneumonia accompanied by pulmonary embolism(observation group),compared with bacterial pneumonia group(control group).Patients with the general information,presence of basic diseases,clinical symptoms and laboratory examination,etc.,are used to explore the clinical characteristics of the observation group and the risk factors;thus,to reduce the missed diagnosis to improve the clinical treatment level.Methods:From January 2017 to July 2019,we collected 359 cases of bacterial pneumonia in Yan'an Hospital affiliated to Kunming Medical University Internal Medicine from hospitalized patients.According to the result of CTPA,all patients were divided into an observation group(155 cases)and control group(204 cases).The two groups were compared based on gender,age,basic disease,clinical symptoms,and laboratory examination index.Results:1.There were 155 patients with an observation group,95 males and 60 females,with an average age of(64.81 ± 10.892).There were 204 patients in the control group,114 males and 90 females,with an average age of(58.39 ± 8.153).According to the analysis of the variance,the average age of the observation group was higher than that of the control group.There was a statistical difference in age(P<0.05),and there was no significant difference in gender between the two groups(P>0.05).2.The number of patients with a basic disease such as hypertension,coronary heart disease,COPD,tumor,diabetes,others basic disease and long-term bed rest in the group with bacterial pneumonia complicated with pulmonary embolism was significantly higher than that in the group with bacterial pneumonia without PE.The difference was statistically significant(P<0.05).3.There was no significant difference in cough,expectoration,fever,and other common symptoms between the two groups(P>0.05).The patients in the observation group were more likely to have hemoptysis,chest pain,dyspnea,and even syncope were statistically significant(P<0.05).4.The level of D-dimer in patients in the observation group was significantly higher than that in control group,and the difference was statistically significant(P<0.05).5.There was a significant difference between the two groups in the sputum culture bacterial detection rate(P<0.05).6.Comparing the type I respiratory failure between the two groups,the patients in the observation group were more likely to have type I respiratory failure than those in the control group(P<0.05).But there was no significant difference in PCO2 between the two groups(P>0.05).7.The average course of disease in the case group(21.12 days)was higher than that in the control group(14.21 days).8.Multivariate logistic analysis of risk factors:the independent risk factor for Bacterial pneumonia and PE are age>60 years,LOS>14 days,chest pain,dyspnea,COPD,cancer,hypertension,coronary heart disease.Conclusions:1.According to the research result,the average age of the observation group was higher than that of the control group.The number of patients with a basic disease such as hypertension,coronary heart disease,COPD,tumor,diabetes,other basic diseases,and long-term bed rest in the group with bacterial pneumonia complicated with pulmonary embolism was significantly higher than that in the group with bacterial pneumonia without PE.2.The patients in bacterial pneumonia associated with the pulmonary embolism group were more likely to have hemoptysis,chest pain,dyspnea,and syncope which,were statistically significant.3.The level of D-dimer in patients with bacterial pneumonia and pulmonary embolism was significantly higher than that in patients with bacterial pneumonia without PE,and the difference was statistically significant.4.There was a significant difference between the two groups in the sputum culture bacterial detection rate.5.Comparing the type I respiratory failure between the two groups,the patients in bacterial pneumonia and pulmonary embolism group were more likely to have type ?respiratory failure than those in the bacterial pneumonia group.6.The average course of disease in the case group was higher than that in the control group.7.Multivariate logistic analysis of risk factors:the independent risk factor for Bacterial pneumonia and PE are age>60 years,LOS>14 days,chest pain,dyspnea,COPD,cancer,hypertension,coronary heart disease.
