再次心脏瓣膜手术高危因素分析

Analysis of High Risk Factors in Heart Valve Re-do

目的对导致再次心脏瓣膜手术围术期步死亡的相关因素进行分析。 方法分析201例行再次心脏瓣膜手术的原始资料,对术前14个变量作单因素及Logistic多元回归分析。 结果 引起围术期死亡的主要相关因素依次为:手术年代、首次手术类型、术前心功能、心胸比例、年龄、射血分数、左室舒张末期内径及心电图有左室肥大伴劳损或右室肥大伴劳损。 结论 再次心脏瓣膜手术围术期死亡与上述因素有关。针对这些相关因素而采取某些避免或相应处理措施,可望降低围术期死亡率。

Objective To identify some independent predictors that might lead to peri-operative deaths in patients with valvalar re-operation. Methods Fourteen preoperative variables in 201 patients were analyzed retrospectively with univariate test and Logistic regression analysis. Results The main causes of peri-operative deaths in sequence were year of operation, type of primary operation, preoperative cardiac function, C/T ratio, age, EF, LVEDD and right left ventricular hypertrophy on ECG. Conclusion There exist some risk factors. Relevant measures to avoid occurrence of these predictors or correction of them could decrease the peri-operative mortality.
