ABSTRACT
Objective To study the diagnostic value of heart fat acid binding protein (h‐FABP) in myocardial damage of children with hand‐foot‐mouth disease (HFMD) .Methods From February 2012 to December 2014 ,100 children with HFMD were chosen as study objects .All children study were divided into 2 sub‐groups according to the severity of disease:71 in ordinary HFMD sub‐group ,29 in severe HFMD sub‐group .At the same time ,100 healthy children were chosen as control group .The routine blood test , rate of abnormal electrocardiography ,rate of abnormal cTnI and rate of abnormal h‐FABP were compared among all children .The cTnI and h‐FABP at different time were compared between ordinary HFMD sub‐group and severe HFMD sub‐group .Results The WBC ,RBC and L had significant difference among different groups/sub‐groups(P0 .05) .In ordinary HFMD sub‐group ,rate of abnormal electrocardiography was 19 .72% (14/71) ,rate of abnormal cTnI was 4 .23% (3/71)and rate of abnormal h‐FABP was16 .39% (10/71);in severe HFMD group ,rate of abnormal electrocardio‐graphy was 72 .41% (21/29) ,rate of abnormal cTnI was 82 .76% (23/29) and rate of abnormal h‐FABP was 82 .96% (23/29);in control group ,rate of abnormal electrocardiography was 1 .00% (1/100) ,rate of abnormal cTnI was 2 .00% (2/100)and rate of ab‐normal h‐FABP was 0 .00% (0/100) ,the difference had statistical significance(P<0 .05) .The cTnI and h‐FABP at different time had significant difference between ordinary HFMD sub‐group and severe HFMD sub‐group(P<0 .05) .Conclusion Heart fat acid binding protein (h‐FABP) can reflect the early myocardial damage in children with hand‐foot‐mouth disease .
