摘要

Objective:To explore change of hemoglobin (Hb) concentration ,the relationship between anemia and left ventricular function and the influence of anemia on prognosis in patients with diastolic heart failure (DHF ) . Methods :According to NYHA classification ,a total of 176 DHF patients were divided into class Ⅱ group (n=78) , class Ⅲ group (n=50) and class Ⅳ group (n=48) ,then Hb level and morbidity rate of anemia were analyzed in each group .According to diagnostic standard of anemia ,patients were divided into anemia group (n=58 ,occupied 33.0% ) and non anemia group (n=118 ,occupied 67.0% ) .Left ventricular diastolic function ,mortality rate and rehospitalization rate during follow‐up were compared and analyzed between two groups .Results:Along with cardi‐ac function class rose (from class Ⅱ to class Ⅳ) ,Hb level showed a decreasing trend [ (130 ± 6) g/L vs .(108 ± 4) g/L vs .(96 ± 12) g/L] ,while morbidity rate of anemia gradually rose (8.97% vs .36.0% vs .68.8% ) P<0.05 all in anemia group ;Compared with non‐anemia group ,there were significant rise in percentages of patients with coro‐nary heart disease (55.1% vs .65.5% ) ,levels of creatinine [ (87.6 ± 39.2)μmol/L vs .(113.7 ± 59.8)μmol/L] and N terminal pro B type natriuretic peptide [NT‐proBNP ,(578.0 ± 136.7) pg/ml vs .(886.0 ± 174.8) pg/ml] , and early‐diastolic peak velocity deceleration time [ (137 ± 15) ms vs .(196 ± 13) ms] ,and significant reduction in mitral early/late diastolic peak flow velocity [E/A ,(0.87 ± 0.32) vs .(0.62 ± 0.29)] , P<0.05 all .Compared with non‐anemia group , there were significant rise in mortality rate (9.3% vs .20.7% ) and rehospitalization rate (18.6%vs .32.8% ) in anemia group during follow‐up , P<0.05 all .Conclusion:DHF patients often complicate with anemia . Along with heart failure aggravates ,their morbidity rate of anemia rises ,and anemia may aggravate cardiac diastolic dysfunction .Mortality rate and rehospitalization rate rise in DHF patients complicated with anemia .%目的:探讨舒张性心力衰竭(DHF)患者血红蛋白(Hb)含量的变化,贫血与左室功能的关系及对预后的影响。方法:176例DHF患者按照NYHA分级分为:Ⅱ级78例,Ⅲ级50例,Ⅳ级48例,分析各组Hb水平和贫血患病率。按照贫血诊断标准患者被分为贫血组(58例,占33.0%)与非贫血组(118例,占67.0),对两组患者左室舒张功能,随访期间的死亡率及再住院率进行比较分析。结果:贫血组随心功能分级(Ⅱ级~Ⅳ级)增加, Hb水平呈下降趋势[(130±6) g/L比(108±4) g/L比(96±12) g/L],而贫血的患病率逐渐增加(8.97%比36.0%比68.8%), P均<0.05。与非贫血组相比,贫血组的冠心病患者比例(55.1%比65.5%)、肌酐[(87.6±39.2)μmol/L比(113.7±59.8)μmol/L]、N 末端 B型利钠肽原[NT‐proBNP ,(578.0±136.7) pg/ml比(886.0±174.8) pg/ml]水平明显升高,舒张早期峰速减速时间明显增加[(137±15) ms比(196±13) ms],二尖瓣舒张早期/晚期峰值流速比值[E/A ,(0.87±0.32) 比(0.62±0.29)]明显减小(P均<0.05)。随访期间与非贫血组比较,贫血组的死亡率(9.3%比20.7%)、再住院率(18.6%比32.8%) 明显上升( P均<0.05)。结论:DHF患者常伴有贫血,随着心衰严重程度的加重其贫血发病率增加,贫血可能加重心脏舒张功能不全,合并贫血的DHF患者其死亡率及再住院率增加。
