摘要目的 分析慢性心功能不全合并贫血患者的临床特点,探讨有效的治疗方法.方法 收集2003-2008年在哈尔滨医科大学附属第一医院心内科住院的心功能Ⅱ～Ⅳ级患者资料,从中再选取出合并贫血的患者.共收集到患者315例,从中选出符合贫血条件的46例.将选出的46例患者分为两组.第1组22例,仅接受改善心功能治疗(常规强心、利尿、扩血管治疗等);第2组24例,接受改善心功能治疗的同时接受抗贫血治疗,口服硫酸亚铁片(0.3g/片),每次1片,每日3次和(或)每周2次皮下注射促红细胞生成素3000 U.两组患者分别在治疗前后进行血常规、心脏彩超检查.观察血红蛋白(Hb)、血红细胞数(RBC)、红细胞比容(HCT)、左室射血分数(LVEF)、左室短径缩短率(FS)、心搏出量(SV)、心输出量(CO)及E峰与A峰比值(E/A).通过逻辑回归,分析心功能分级与贫血发生的相对危险度(RR).结果 ①在心功能Ⅱ、Ⅲ、Ⅳ级患者中,贫血的发病率分别为7.9%(10/126)、19.2%(23/120)和24.6%(17/69).Ⅲ、Ⅳ级与Ⅱ级贫血发病率比较,差异有统计学意义(x2值分别为4.08、3.12,P均＜0.05).②治疗后第1组与第2组患者Hb[(101.3±6.31)、(130.7±5.75)g/L]、RBC[(0.36±0.08)×1012/L、(0.43±0.02)×1012/L]、HCT[(15.6±1.8)%、(18.0±2.5)%]、LVEF[(4.4±1.6)%、(5.1±1.2)%]、FS[(3.49±0.17)%、(4.12±0.25)%]、SV[(48.9±3.1)%、(58.5±2.7)%]、CO[(38.9±3.7)%、(49.1±7.7)%]比较差异有统计学意义(t值分别为3.765、2.898、3.221、3.197、4.018、3.775、2.264,P均＜0.05).③第2组患者治疗前Hb[(102.7±6.9)g/L]、RBC[(0.35±0.07)×1012/L]、HCT[(16.0±2.4)%]、LVEF[(3.7±1.4)%]、FS[(3.41±0.12)%]、SV[(47.5±2.9)%]、CO[(38.2±7.9)%]与治疗后比较差异有统计学意义(t值分别为15.632、13.325、5.569、17.182、3.186、2.999、3.074,P均＜0.05).④逻辑回归分析心功能分级与贫血发生的相对危险度结果显示,心功能Ⅲ、Ⅳ级患者RR分别为1.62、3.14(P＜0.05或＜0.01).结论 慢性心功能不全患者在常规治疗基础上,同时治疗贫血,可以改善心脏收缩功能.

abstractsObjective To find the effective therapeutic arrangement through investigating the clinical characteristics of chronic cardiac insufficiency with anaemia. Methods A total of 46 cases of anemia from 315patients who had been admitted to department of cardiology, the First Affiliated Hospital, Harbin Medical University for chronic cardiac insufficiency with anaemia were selected. They were divided into two groups. There were 22 patients in the first group who only accepted treatment to improve cardiac function (normal cardiac, diuretic,vasodilator therapy, etc.), and 24 patients in the second group who accepted treatment to improve cardiac function while receiving anti-anemia therapy treatment, oral ferrous sulfate tablets(0.3 g/tablet), 1 tablet each time, 3 times a day and(or) 2 times per week subcutaneous erythropoietin 3000 U. The hemoglobin(Hb), red blood cell(RBC) ,hematocrit (HCT), left ventricular ejection fraction (LVEF), fractional shortening (FS), stroke volume (SV) , cardiac output(CO) and E peak and A peak ratio(E/A) were observed before and after treatment. By logistic regression, grade grade Ⅱ , Ⅲ , Ⅳ, the incidence of anaemia were 7.9% (10/126), 19.2% (23/120) and 24.6% (17/69),respectively. Grade Ⅱ compared with grades Ⅲ, Ⅳ, the difference was statistically significant (x2 = 4.08, 3.12, all (3.49 ± 0.17) × 1012/L, (0.36 ± 0.08)%, (48.9 ± 3.11)%, (15.6 ± 1.8)%, (38.9 ± 3.7)%, (4.4 ± 1.6)% and (130.7 ±5.75)g/L, (4.12 ± 0.25) × 1012/L, (0.43 ± 0.02)%, (58.5 ± 2.65)%, (18.0 ± 2.5)%, (49.1 ± 7.7)%, (5.1 ± 1.2)%in the first and second groups, respectively. The difference between the two groups was statistically significant(t =value of Hb, RBC, HCT, LVEF, FS,SV, CO were (102.7 ± 6.93)g/L, (3.41 ± 0.12) × 1012/L, (0.35 ± 0.07)%,(47.5 ± 2.86)%, (16.0 ± 2.4)%, (38.2 ± 7.9)%, (3.7 ± 1.4)%, respectively. Compared with those after treatment,the difference was statistically significant (t = 15.632, 13.325, 5.569, 17.182, 3.186, 2.999, 3.074, all P ＜ 0.05);Ⅳ-level relative risk were 1.62, 3.14(P ＜ 0.05 or ＜ 0.01) . Conclusions Based on the standard treatment with treatment of anemia, cardiac contractile function can be improved.
