中重度贫血对老年顽固性心力衰竭患者的影响

目的探究中重度贫血对老年顽固性心力衰竭患者预后及病死率的影响。方法随机选取并回顾性分析2010年1月至2012年1月于我院治疗顽固性心力衰竭合并贫血的老年患者51例(研究组)及非贫血顽固性心力衰竭老年患者51例(对照组)。对比两组患者再住院率及病死率,同时比较不同程度贫血的预后及病死率。结果研究组患者再住院率及病死率明显高于对照组,且两组差异存在统计学意义(P<0.05)。轻度贫血组患者病死率与中、重度贫血组存在明显统计学差异(χ2=5.37,P=0.016),且两组患者1年后LEVF、LVEDV存在明显统计学差异(P<0.05)。结论贫血可提高老年顽固性心力衰竭患者的病死率,且贫血越严重,病死率越高。控制患者贫血程度对于降低顽固性心力衰竭老年患者的病死率和再住院率有积极作用。

The Effect of Moderate to Severe Anemia on Patients of Senile Refractory Heart Failure

Objective To discuss the effect of moderate to severe anemia on patients of senile refractory heart failure.Methods Choosed 51 patients of senile refractory heart failure combined moderate to severe anemia as study group,and choosed 51 patients of senile refractory heart failure without moderate to severe anemia as controlled group from Jan.2010 to Jan.2012.Compared relationship of degrees of anamia with rehospitalization rate and dead rate.Results The rehospitalization rate and dead rate in study group was higher than controlled group（P0.05）.And Dead rate of moderate anemia patients was lower than moderate and severe anemia patients.Conclusion Degrees of anemia could increase dead rate of senile refractory heart failure.We should controll anemia to decrease dead rate and rehospitalization rate of senile refractory heart failure.
