The causes of increased cardiac enzymes in newborns are as follows: 1, some of the increased cardiac enzymes in newborns are normal, that is, it is a transient elevation, because when the newborn is born, with the mother’s uterine contractions, the umbilical cord or placental blood flow may be interrupted, there will be a transient lack of oxygen; or the child is born in the normal way, after the birth canal extrusion; 2, or there will be violent crying before the child’s blood is drawn, because the muscle enzymes The increase in creatine kinase in the cardiac enzymes will cause a transient increase, which may return to normal after the child is rechecked or the blood is drawn again after a period of time; 3, in addition, it is a pathological phenomenon, if the child’s jaundice level is particularly high, the increase in jaundice will also damage his heart muscle, which will also cause an increase in cardiac enzymes; 4, there is also an infection, whether it is a bacterial infection, or If it is a transient increase, it basically has no effect on the child, but if it is late, including hypoxia, jaundice, and some viral or bacterial infections caused by the increase in cardiac enzymes, some respiratory drugs will be used to bring it back to normal.
