摘要
目的 :探索体重和肺心病预后的关系 ,我国肺心病患者中实际体重和理想体重之比 (IBW% )和体重指数 (BMI)的关系 ,为在我国肺心病患者预后预测中应用 BMI提供依据。方法 :19例肺心病患者 ,记录确诊时的身高和体重 ,随访 6 3个月 ,比较生存组和死亡组的体重指标 (IBW%、BMI)及生存时间的差异 ,对19例患者作生存分析 ,对死亡组作生存时间和体重之间的相关和回归并比较两回归方程的差异。结果 :生存组和死亡组之间的体重指标差异显著 ,两组生存时间差异显蓍 ,19例患者 5年生存率为 0 .474,BMI<2 1kg/m2 者 5年中死亡的相对危险度为 3.2 5 ,死亡组的生存时间和体重指显著相关 ,体重指标中 IBW%和 BMI均可反映这种相关性 ,但 BMI的 t值、F值和 r值均大于 IBW% ,两者的直线回归方程比较有显蓍差异。结论 :肺心病患者预后和体重相关 ;BIM<2 1kg/ m2 者 ,相对死亡危险度较大 ;BIM在我国肺心病患者预后预测中有重要应用价值。
Objective: To explore the relation between weight and prognosis, IBW% and BMI in Chinese cor pulmonale patients and to provide the proof for predicting the prognosis using BMI in Chinese cor pulmonale patients. Methods: High and weight were recorded in 19 cases of cor pulmonale patients when final diagnosis were confirmed and 19 cases were followed up for 63 month. The difference of the survival time and the index of weight(IBW%, BMI) between dead and survival groups was compared. The survival analysis were made in 19 cases. The relation and regression between weight and survival time in death group were recorded and the comparison between two regressive equations were made. Results: The difference of the survival time and the index of weight between two groups are notable. The survival rate of 19 patients for 5 years is 0.474. The relative risk of death within 5 yeras is 3.25 if BMI is less than 21kg/m 2. The relation between survival time and index of weight in death group is striking. Both IBW% and BMI can explain the relation but the value of t, F nad r of BMI is higher than that of IBW%. The difference between two regressive equations is significant. Conclusions: The weight and the prognosis of patient with cor pulmonale is relative. If BMI is less than 21kg/m 2 the relative risk of death will be greater. BMI has the important practical value on predicting the prognosis of Chinese cor pulmonale patients.
