【摘要】 目的 探讨联合检测D-二聚体与缺血修饰白蛋白(IMA)诊断心力衰竭的临床价值。
方法 42例心力衰竭患者作为心力衰竭组(心功能Ⅱ级19例、Ⅲ级16例、Ⅳ级7例), 42例进行体检的健康人作为健康组, 检测两组D-二聚体、IMA及B型脑钠肽(BNP)水平, 并进行比较;同时常规治疗心力衰竭患者, 并检测不同心功能患者治疗后D-二聚体、IMA、BNP水平。结果 心力衰竭组D-二聚体、BNP、IMA水平分别为(1.31±0.24)μg/ml、(941.8±144.2)pg/ml、(91.5±12.5)U/ml, 均高于健康组的(0.20±0.06)μg/ml、(127.6±41.8)pg/ml、(67.2±10.7)U/ml, 差异均具有统计学意义(P<0.05)。治疗后心功能Ⅳ级患者D-二聚体、BNP、IMA水平均高于心功能Ⅱ级与心功能Ⅲ级患者, 差异均具有统计学意义(P<0.05);治疗后心功能Ⅲ级患者D-二聚体、BNP、IMA水平均高于心功能Ⅱ级患者, 差异均具有统计学意义(P<0.05)。结论 联合检测D-二聚体与IMA可有效诊断心力衰竭, 并对治疗后效果予以评估, 心功能越差者治疗效果越差, 值得推广。

【Abstract】 Objective To discuss the clinical value of D-dimer and ischemia modified albumin (IMA) for combined detection of heart failure. Methods There were 42 heart failure patients as heart failure group (19 cardiac function grade Ⅱ cases, 16 grade Ⅲ cases and 7 grade Ⅳ cases), and 42 healthy people as healthy group. The D-dimer, IMA and B-type natriuretic peptide (BNP) level in two groups was detected and compared. The patients with heart failure were received routine treatment, and the levels of D-dimer, IMA, BNP after the treatment of patients with different grades of heart function were detected. Results Heart failure group had D-dimer, BNP and IMA level respectively as (1.31±0.24) μg/ml, (941.8±144.2) pg/ml and (91.5±12.5) U/ml,
which were all higher than (0.20±0.06) μg/ml, (127.6±41.8) pg/ml and (67.2±10.7) U/ml in healthy group, and their difference was statistically significant (P<0.05). After treatment, cardiac function grade Ⅳ patients had higher D-dimer, BNP and IMA level than grade Ⅱ and Ⅲ patients, and their difference was statistically significant (P<0.05). After treatment, cardiac function grade Ⅲ patients had higher D-dimer, BNP and IMA level than grade Ⅱ patients, and the difference was statistically significant (P<0.05). Conclusion Combined detection of D-dimer and IMA can effectively diagnose heart failure. The effect of treatment after treatment is evaluated. The worse the heart function is, the worse the treatment effect. It is worth popularizing.

心力衰竭是心臟损害引起的心排血量减少, 不能满足组织代谢需要的一种综合征。临床上以肺循环和(或)体循环淤血以及组织血液灌注不足为主要特征。心力衰竭的诊断主要依靠X线、心电图、超声心动图或磁共振成像(MRI)检查, 实验室检测主要是BNP。本病病情危急, 因此快速诊断、判断严重程度对控制病情发展与降低潜在死亡率意义重大。心力衰竭不仅会削弱心脏泵功能, 还会因此产生系列变化, 于疾病不同阶段各种标志物产生。近年来研究表明D-二聚体与BNP水平密切关联于心力衰竭[1], 因此临床将其作为主要诊断治疗指标。……
