目的：探讨脓毒症心肌损伤患者心型脂肪酸结合蛋白（H-FABP）和 N-末端脑钠肽前体（NT-proBNP ）的变化及临床意义。方法：118例脓毒症患者按预后分为存活组68例和死亡组50例；体检者50例为对照组。脓毒症患者入院1 h （发病3 h内）、6 h 时，对照组体检时检测心肌酶、H-FABP及NT-proBNP水平、APACHEⅡ评分及28 d病死率。结果：入院1 h，脓毒症患者H-FABP、NT-proBNP和APACHEⅡ评分高于对照组（P ＜0．05），6 h 时 cTnI、H-FABP、NT-proBNP 和 APACHEⅡ评分高于1 h（P ＜0．05）；死亡组在1 h和6 h 时 H-FABP、NT-proBNP 和 APACHEⅡ评分高于存活组（ P ＜0．05）；6 h 时死亡组 cTnI 高于存活组（P ＜0．05）。患者6 h时 H-FABP 和NT-proBNP 与cTnI 呈正相关（均 P ＜0．05）。6 h 时 H-FABP 对28 d 病死率的预测能力优于NT-proBNP及APACHEⅡ评分（P ＜0．05）。结论：H-FABP和NT-proBNP对脓毒症患者心肌损伤的早期诊断和预后评估有重要意义。%Objective To investigate the clinical value of heart-type fatty acid-binding protein ( H-FABP) and N terminal probrain natriuretic peptide (NT-proBNP) in sepsis patients with myocardium injury. Methods 118 sepsis patients were included as survivor group (68 cases) and death group (50 cases) according to their prognosis outcome. 50 healthy people were selected as control group. Creatase, H-FABP, NT-proBNP, APACHEⅡscore and 28 day morbidity of control group and sepsis patients were assessed at 1 h, 6 h after admission by physical examination . Results At 1 h after admission , APACHEⅡscore , H-FABP and NT-proBNP level in sepsis patients were significantly higher than control group (P < 0.05); APACHEⅡscore, H-FABP, NT-proBNP and cTnI level at 6 h after admission were higher than that at 1 h (P < 0.05); APACHEⅡscore, H-FABP and NT-proBNP level in death group were higher than survivor group at 1, 6 h after admission (P < 0.05), cTnI level at 6 h after admission was higher in death group (P < 0.05). Futhermore, H-FABP, NT-proBNP and cTnI at 6 h after admission were positively correlated with each other (both P < 0.05). At 6 h after admission , H-FABP showed a better predictive value of 28-day mortality than NT-proBNP and APACHEⅡscore (P < 0.05). Conclusion H-FABP and NT-proBNP may suggest important significance in early diagnosis and prognosis prediction of sepsis patients with myocardium injury.
