扩张型心肌病120例左室质量与生存率分析

Analysis of the Relativity Between Left Ventricular Mass(LVM) and Survival Rate in Dilated Cardiomyopathy of 120 Cases

目的：探讨扩张型心肌病（Dilated Cardiomyopathy．DCM）患者左室质量与生存率关系。方法：1998年6月～2004年6月DCM住院患者120例，应用超声心动图进行左室质量（Left ventr icular mass．LVM）分析．必要时行冠状动脉造影、核素心肌灌注显像．并随访终点至2006年6月（随访时间3月～8年）．探讨与其生存率的关系。结果：120例DCM患者左室质量指数（LVMl）为（185.30±64.62）g／m^2．明显高于正常值。至随访终点共死亡60例．占50％（60／120）．死亡组LvMl为（240.89±78.32）g／m^2，明显高于非死亡组（P〈O.05）。其中自症状出现后3～12月内死亡8例（6.67％）．LVMI为（256.03±85.26）g／m^2；1～5年内死亡24例（20.00％）．LVMI为（220.83士71.44）g／m^2；生存达5年以上者28例（23.33％）．LVMI为（142.50士44.32）g／m^2，3组差异有显著性意义（P〈O.01）。结论：DCM患者LVMI与其生存率密切相关．对评估DCM患者的预后有一定的帮助。

Objective:To explore the relativity between left ventricular mass(LVM) and survival rate in Dilated Cardiomyopathy(DCM) patients. Methods:Collect 120 DCM cases in hospital from 1998.06 to 2004.06,then analyze LVM by ultrasonic value of heart,and discuss the relativity between LVM and survival rate,end in 2006.06(following 3months-8years).Results:The LVMI of 120 DCM cases is 185.3±64.62,higher than the norm in evidence. Following 3months-8years,there are 8 death cases(6.7%) in 3 months-12 months,LVMI is 256.03±85.26,24 death cases(20.0%) in 1 years-5 years,LVMI is 220.83±71.44,and 24 death cases(23.3%) up to 5 years,LVMI is 142.50±44.32. The diversity of three groups is notable(P<0.01).The LVMI of death groups is 240.89±78.32,higher than non-death groups in evidence(P<0.005).Conclusion:There is close relativity between LVM and survival rate,it is beneficial for evaluating prognosis of DCM patients.
