节段性室壁运动异常对扩张型心肌病预后的影响

Segmental wall motion abnormalities on the prognosis of dilated cardiomyopathy

目的 探讨节段性室壁运动异常对扩张型心肌病预后的影响.方法 选取我院2010年1月~2013年1月确诊为扩张型心肌病患者65例,经二位超声心动描记术检查和目测半定量室壁运动记分法分为普通运动减弱组（34例）和节段性室壁运动异常组（31例）.通过随访观察对比两组患者心腔收缩功能、无心脏事件累计生存率等预后的差异.结果 节段性室壁运动异常组的收缩功能比普通运动严重,射血分数（32±5）%：（37±6）%,左室内径缩短率＜25%,左室舒张期末内径（73±5）：（67±4）mm,差异具有统计学意义（P＜0.01）.结论 节段性室壁运动异常是扩张型心肌病预后不良的预测因子.

Objective To investigate the segmental wall motion abnormalities on the prognosis of dilated cardiomyopathy. Methods From January 2010 to January 2013, diagnosed with dilated cardiomyopathy patients, 65 cases the by two ultrasound echocardiography intraoperative inspection and visual semi - quantitative wall motion scoring method is divided into ordinary motion decreases group （34 cases） and segmental wall motion abnormalities group （31 cases）. Follow-up study to compare two groups of patients with heart chamber systolic function, cumulative cardiac event-free survival rate and prognostic differences. Results Seg- mental wall motion abnormalities group systolic function more serious than ordinary exercise, ejection fraction （32 ± 5 ）% ： （37 ± 6） %, left ventricular shortening fraction 〈 25% ,left ventricular end-diastolic diameter （73± 5 ） ： （67± 4） mm, the difference was statistically significant （P 〈 0.01 ）. Conclusion Segmental wall motion abnormalities dilated cardiomyopathy predictor of poor prognosis.
