并发症对肺心病死亡影响程度的分析

目的探讨并发症对慢性肺心病死亡的影响。方法回顾性研究237例慢性肺心病老年患者并发症和死亡的资料。结果并发症与病死率呈正相关（P=0.0000）;死亡组人均并发症数显著高于非死亡组（P〈0.0001）;多脏器功能衰竭、呼吸衰竭、心力衰竭、肾功能衰竭、电解质紊乱、心律失常、营养不良及合并肺炎为影响死亡的重要因素（P=0.0000-0.0289）。结论防治和减少并发症,纠正脏器功能衰竭等,可改善肺心病的预后。将并发症控制在3项以内,可显著降低病死率。

Analaysis of effect of the complications as related to cor pulmonale death

Objective To explore the effect of the complications as related to cor pulmonale death.Methods Clinical data of 237 elderly chronic cor pulmonale patients were retrospectively reviewed and analyzed.Results The occurrence of complications and the mortality rate were positively correlated：P〈0.0001.The mean complication was higher in the death group than that in the survival group：P〈0.0001.The causes for the death included multi-organ function failure,respiratory failure,heart failure,renal failure,serious electrolyte abnormal,malnutrition and pneumonia.（P value ranging between 0.001 and 0.0289）.Conclusion To reduce the mortality rate,we should prevent and reduce the complications,correct the possible organ＇s failures,improve the respiratory and heart functions and have the number of complications controlled within 3.
