摘要目的：通过前瞻性观察慢性心力衰竭（CHF）患儿血浆心型脂肪酸结合蛋白（h-FABP）的水平变化及其与心功能的关系，探讨其在CHF中的临床价值。方法：36例CHF患儿（CHF组）纳入研究，其中心内膜弹力纤维增生症16例（EFE组），扩张型心肌病20例（DCM组）。选择同期30例健康儿童作为对照组。血浆h-FABP浓度测定采用酶联免疫吸附法（ELISA），并以心脏超声心动图测量心脏指数、左室短轴缩短率及左室射血分数。结果：CHF患儿血浆h-FABP浓度明显高于对照组（21.7±4.3 ng/mL vs 6.2±1.7 ng/mL, P＜0.01），且心力衰竭程度越重，h-FABP浓度升高越明显（P＜0.01）。EFE、DCM两组hFABP水平均高于对照组（P＜0.01）。CHF患儿h-FABP水平与左室射血分数、心脏指数及左室短轴缩短率均呈明显负相关（分别r=-0.65、-0.64、-0.71，均P＜0.01）。结论：CHF患儿的血浆h-FABP浓度明显升高，血浆hFABP浓度与心力衰竭的严重程度相关。血浆h-FABP浓度可作为评估心力衰竭及其严重程度的一个指标。

Abstract：OBJECTIVE: To study serum levels of heart-type fatty acid-binding protein (h-FABP) in children with chronic heart failure (CHF), and the correlation between heart function and the level of h-FABP, with the aim of studying the significance of h-FABP in CHF. METHODS: Thirty-six children with CHF, including 16 cases of endocardial fibroelastosis (EFE) and 20 cases of dilated cardiomyopathy (DCM) were enrolled in the study. Thirty healthy children sevred as the control group. Serum levels of h-FABP were determined using ELISA, and left ventricular ejection fraction (LVEF), cardiac index (CI) and fractional shortening of the left ventricle (LVSF) were measured by two-dimensional echocardiography in the CHF group. RESULTS: Mean levels of h-FABP in the CHF group were significantly higher than in the control group (21.7±4.3 ng/mL vs 6.2±1.7 ng/mL; P<0.01). The worse the heart function, the higher the h-FABP levels (P<0.01). Mean levels of h-FABP in both the EFE and DCM groups were significantly higher than in the control group (P<0.01). Serum h-FABP concentrations were negatively correlated with LVEF, CI and LVSF (r=-0.65, -0.64 and -0.71 respectively; P<0.01) in the CHF group. CONCLUSIONS: Serum h-FABP levels increase in children with CHF and are closely related to the severity of the condition. Serum h-FABP levels can be used as a biomarker for the diagnosis of heart failure and the evaluation of its severity.
