不同体质量指数肺栓塞患者的临床表现与生存状况比较

Comparison of clinical characteristics and living conditions of patients with pulmonary embolism under different body mass index

目的分析不同体质量指数(BMI)肺栓塞患者的临床表现与生存状况。方法选取96例肺栓塞患者为研究对象,按照BMI将患者分为肥胖组(BMI≥28kg/m^2)、超重组(24kg/m^2≤BMI<28kg/m^2)和正常组(18kg/m^2≤BMI<24kg/m^2),分别为27、33、36例,比较3组患者各种临床表现发生率,血红蛋白和红细胞比容水平,以及1年后生存率,并使用Pearson相关分析法分析BMI与各临床表现的发生率,血红蛋白和红细胞比容水平,以及1年后生存率的相关关系。结果肥胖组、超重组咳嗽、发热、呼吸困难、胸痛的发生率明显高于正常组,且肥胖组咳嗽、发热、呼吸困难、胸痛的发生率明显高于超重组,差异均有统计学意义(P<0.05)。肥胖组、超重组的血红蛋白和红细胞比容水平明显高于正常组,肥胖组的血红蛋白和红细胞比容水平明显高于超重组,差异均有统计学意义(P<0.05)。肥胖组、超重组、正常组1年后的生存率分别为69.23%、75.76%、88.89%,差异均有统计学意义(P<0.05)。BMI与各种临床表现发生率,血红蛋白、红细胞比容水平,以及1年后生存率呈显著相关(r=0.344、0.551、0.468、-0.613)。结论BMI越高,肺栓塞患者咳嗽、发热、呼吸困难、胸痛的发生率越高,血红蛋白和红细胞比容水平越高,生存率越低。

Objective To explore the clinical characteristics and survival status of patients with pulmonary embolism under different body mass index(BMI).Methods A total of 96 patients with pulmonary embolism were selected as subjects,and divided into obese group(BMI≥28 kg/m^2,27 cases),super-recombination(24 kg/m^2≤BMI<28 kg/m^2,33 cases)and normal group(18 kg/m^2≤BMI<24 kg/m^2,36 cases)according to BMI.The incidence of clinical characteristics,hemoglobin and hematocrit levels,survival rate after 1 year in the three groups were compared.Pearson′s method was used to analyze the relationship between BMI and incidence of clinical characteristics,hemoglobin and hematocrit levels,and survival rate after 1 year.Results The incidence of cough,fever,dyspnea and chest pain in the obese group were significantly higher than those in the normal group,and those in the obese group were significantly higher than those in the super-recombination group,with statistically significant differences(P<0.05).The hemoglobin and hematocrit levels in the obese group and the super-recombination group were significantly higher than those in the normal group,and those in the obese group were significantly higher than those in the super-recombination group,with statistically significant differences(P<0.05).The 1 year survival rates of the obese group,the super-recombinant group,and the normal group were 69.23%,75.76%and 88.89%respectively,with statistically significant differences(P<0.05).BMI correlated with the incidence of various clinical characteristics,hemoglobin and hematocrit levels,and 1 year survival rate(r=0.344,0.551,0.468,-0.613).Conclusion The higher the BMI is,the higher the incidence of cough,fever,dyspnea and chest pain in patients with pulmonary embolism,the higher the hemoglobin and hematocrit levels,the lower the survival rate are.
