摘要
目的探讨心瓣膜置换术的危险因素,以提高手术治愈率。方法回顾性分析253例心瓣膜置换术患者的临床资料,对心瓣膜置换术的潜在危险因素进行单因素分析,采用logistic回归进行多因素分析。结果术后顺利恢复240例,术后发生并发症13例,其中治愈7例,死亡6例。经单因素分析及多因素logistic回归分析,心功能Ⅳ级,年龄≥70岁,合并慢性阻塞性肺病,LVEDD≥70mm,合并CABG,主动脉阻断时间>2h,体外循环时间>3h是影响心瓣膜置换术的独立危险因素。结论重视影响心瓣膜置术的独立危险因素的处理,对提高其疗效有重要意义。
Objective To explore the risk factors of heart valve replacement,in order to improve the operation cure rate.Methods 253 patients with heart valve replacement of clinical data were analyzed retrospectively.Results 240 patients were operated and recovered well,postoperative complications were 13 cases,including 7 cases were cured,6 cases were died.Through the analysis of list for single factor analysis and logistic regression analysis results of multiple factors,the heart Ⅳ level,age ≥70 years old,merger chronic obstructive pulmonary disease,LVEDD ≥70 mm,heart valve replacement coronary artery bypass graft,the aortic blocking time〉 2h and the extracorporeal circulation time〉 3h were the independent risk factor which affect heart valve replacement.Conclusion More attention to treating the intraoperative independent risk factors which affect heart valve repalacement,it has an important meaning to improve the clinical effects.
