慢性心力衰竭时血红蛋白水平对预后的影响

The effect of the hemoglobin lever on the prognosis of chronic heart failure

目的研究慢性心力衰竭(CHF)患者血红蛋白(Hb)水平对其预后的影响。方法观察142例初次入院的CHF患者Hb与心功能的关系;并进行随访1年,对比在随访期间贫血组和非贫血组患者死亡、再住院次数、再住院总时间。结果贫血发生率36.6%.心衰患者随着心功能恶化,Hb水平逐渐降低(P<0.05),贫血发生率明显升高(P<0.05);在随访期间,贫血组的死亡率比非贫血组提高了3倍.平均住院次数增加了近2倍.平均住院时问也增加了30%,贫血组和非贫血组患者相比.死亡率、平均住院次数和平均住院时间差异均有统计学意义(均P<0.05)。结论贫血在CHF患者中常见,对CHF患者,Hb水平降低或贫血是预后不良因素之一。

Objective To investigate whether the level of hemoglobin（Hb） affected the prognosis of patients suffered from chronic heart failurc（CHF）. Methods 142 patients with CHF were evaluated by the relationship be-tween the level of Hb and cardiac insufficiency. The mortality, times of recurrent hospitalization and length of recurrent hospital stay wcre followed up for one year. Results 36.6 % of CHF patients suffered anaemia, and the lever of Hb decreased and mobidity of anaemia increased respectively with the deterioration of the cardiac function. During the follow-up,mortality, average rimes of hospitalization, and average length of hospital stay in the anaemia group were higher significantly than those the none-anaemia group. Conclusion Prognosis of CHF patients was partially affected by the low Hb or anaemia,which often happened to CHF patients.
