摘要目的 研究不同病因所致老年心力衰竭患者CA125的变化情况,探讨与血B型脑钠肽(BNP)间的关系.方法 155例确诊的慢性心力衰竭患者,按照纽约心脏学会(NYHA)心功能分级Ⅲ级或Ⅳ级的老年患者作为研究对象,根据患者病因分为高血压组、冠心病组、心肌病组及其他病因组,选取25例健康体检老年人为对照组;采用化学免疫发光法定量测定血清CA 125值,采用微粒子酶联免疫检测法定量测定血浆BNP水平,将各组间的CA 125值进行比较,并对CA 125与BNP间的相关性进行分析.结果 高血压组、冠心病组、心肌病组及其他病因组血清CA125值分别为(83.4±6.6)U/L、(36.8±1.4) U/L、(38.1±1.6)U/L及(38.4±1.4)U/L,高于对照组(14.3±1.15)U/L,差异有统计学意义(均P＜0.05);其中高血压组CA125值高于其他各组(P＜0.05),且与BNP呈正相关(r=0.67,P＜0.05).结论 CA 125值可作为诊断心力衰竭的筛选指标,且对评价引起心力衰竭的病因有一定的预测价值.

abstractsObjective To investigate the effect of different etiology on the serum level of carbohydrate antigen 125 (CA125) in elderly patients with chronic congestive heart failure (CHF), and to assess any correlation of CA125 with serum level of B-type natriuretic peptide (BNP). Methods The 155 aged patients with New York Heart Association (NYHA) class Ⅲ or Ⅳ were enrolled and grouped into four reasons of hypertension, coronary heart disease (CHD), cardiomyopathy and other reasons, and 25 healthy old persons as control.CA125 and BNP levels were measured by automatic chemiluminescent immunoassay and enzyme immunoradiometric assay, respectively. Results CA125 level in patients with CHF was (83.4±6.6)U/L for hypertension, (36.8±1.4)U/L for CHD, (38.1±1.6)U/L for cardiomyopathy and (38.4±1.4)U/L for other reasons, which significantly higher than for healthy controls [(14.3±1.15) U/L, P＜0.05].Especially, CA125 level in hypertension group was notable higher than in other reasons of group (P＜0.05), and was positively related to BNP level (r=0.67,P＜0.05). Conclusions Serum CA125 level is a predictor for clinical pathogen of CHF.Therefore, it may be a useful additional marker for the evaluation of clinical treatment of these patients
