摘　　要：目的　观察重症心脏瓣膜病患者手术前后左心功能变化 ,探讨影响手术预后的左心功能指标。方法应用超声心动图检测 4 8例重症心瓣膜病瓣膜置换术患者手术前后左心功能各指标的变化 ,包括左室收缩末期内径 (ESD)、左室舒张末期内径 (EDD)、左室舒张末期容积指数 (EDVI)、左室收缩末期容积指数 (ESVI)、左室心肌质量指数 (L VMI)、左室射血分数 (EF)、左室内径缩短率 (FS)、心脏指数 (CI)。并根据术前 EF值将患者分为 A组2 8例 (EF≥ 4 0 % )和 B组 2 0例 (EF<4 0 % )。另选 10例健康人作为对照组。结果　 A组死亡 1例 ,B组死亡 6例。手术死亡率及术后心功能状况两组差异显著 (P<0 .0 5 )。A组术后除 EF外 ,余各项心功能指标均较术前显著改善 (P<0 .0 5 ) ,除 L VMI仍显著高于对照组 (P<0 .0 1)外 ,余各项心功能指标均恢复到正常范围 (P<0 .0 5 ) ;B组术后除 EF、FS外 ,各项心功能指标较术前有显著改善 (P<0 .0 5 ) ,但与对照组相比仍差异显著 (P<0 .0 5 )。结论　 EF、ESVI、FS。Objective To observe pre and post operative left ventricular function by echocardiography in patients with severe valvular diseases treated by valve replacement and to investigate the parameters of left ventricular function affecting the surgical prognosis.Methods Pre and post operative(2 weeks after operation) left ventricular functions were measured in 48 patients with severe valvular diseases and all patients were divided into two groups lased upon pre operative left ventricular ejection fraction(EF).Group A(28 cases):EF≥0.4;Group B(20 cases):EF<0.4.10 healthy subjects were chosen as a control group.Results 1 case in group A and 6 cases in group B died.The death rate was significantly different between the two groups(P<0.05).In group A,except for EF,other parameters of left ventricular function returned to normal(P<0.05).In group B,except for EF and FS,other parameters improved significantly(P<0.05).Conclusion EF,ESVI,FS and ESD can be used to evaluate the surgical prognosis of patients with severe valvular diseases.
