Clinical Features Of Different Risk Stratification And Adverse Prognostic Factors In Patients With Acute Pulmonary Embolism

Objective: By analyzing the clinical data of clinical characteristics and adverse prognosis of patients with different risk stratification of acute pulmonary embolism(APE)were analyzed,aiming to analyze the common clinical indicators used to predict different risk stratification in patients with acute pulmonary embolism,analyze the relevant factors affecting the poor prognosis of patients with acute pulmonary embolism,and provide help for clinical diagnosis,treatment and long-term prognosis.Methods:Analyzing the hospitalized patients with acute pulmonary embolism diagnosed in our hospital from 2011 to 2022,and 243 patients who met the criteria were included,divided into low-,mediumand high-risk acute pulmonary embolism groups,and the research elements were statistically processed,and conducted research on the actual situation in the end.Results:1.The individuals with relatively high risk and moderate risk are both relatively older and significantly longer than the low-risk group.For individuals with higher risk,their hospitalization time is significantly longer than the other two groups,and the probability of losing their lives during hospitalization is higher in this group than in the other two groups,this difference has research significance(P<0.05)).2.Individuals with high risk have a relatively high probability of stroke in the last one month,and significantly more than the other two groups.For patients with moderate risk,their probability of lower limb vein thrombosis is relatively high,significantly more than the other two groups,and the difference has significant research significance(P<0.05).3.The incidence of chest pain,syncope and dyspnea in the high-risk group was higher than that in the intermediate-risk group and the low-risk group,the incidence of dyspnea and syncope in the intermediate-risk group was higher than that in the low-risk group,and the three groups had a statistically significant difference in the three clinical manifestations of chest pain,dyspnea and syncope(P<0.05).4.Compared with the low-risk group and the intermediate-risk group,the D-dimer level and WBC count of the high-risk group were higher than those of the low-risk group and the intermediate-risk group,while the blood oxygen saturation,oxygen partial pressure,HGB level and RBC count were lower than the intermediate-risk group and the low-risk group,the D-dimer level and WBC count of the intermediate-risk group were higher than that of the low-risk group,while the HGB level and RBC count were lower than that of the low-risk group;The incidence of pleural effusion in the high-risk group was higher than that in the intermediate-risk and low-risk groups,the incidence of pleural effusion in the intermediate-risk group was higher than in the low-risk group,and the incidence of pulmonary hypertension in the intermediate-risk and high-risk groups was higher than in the low-risk group.There were significant differences in oxygen saturation,partial pressure of oxygen,HGB level,RBC count,WBC count,D-dimer level,pleural effusion,and incidence of pulmonary hypertension between the three groups of APE patients(P<0.05).5.The incidence of strokein the past 1 month,pulmonary hypertension,pleural effusion,syncope,oxygen saturation,oxygen partial pressure and D-dimer level are related to risk stratification in patients with APE.6.Combined with active malignant tumor,syncope,WBC count level,and arterial oxygen saturation are related to the poor prognosis of APE patients,and are all independent factors.Conclusion: 1.The incidence of stroke,pulmonary hypertension,pleural effusion,syncope,arterial oxygen saturation,oxygen partial pressure and D-dimer level of APE in the past 1 month are related to its risk stratification.2.Combined with active malignant tumor,syncope,WBC count level,and arterial oxygen saturation are related to the poor prognosis of APE patients,and are independent factors.
