[Myocardial infarction and myocardial ischemia in newborn children and infants, not secondary to an abnormal coronary].
Three cases (one, newborn infant and two infants--one of them recently published--) who present electrocardiographic and enzymatic alterations comparative with diagnosis of ischemia and myocardial infarction are reported. Rarity of this entity in infants is stressed as most of published cases are secondary to ananomolous coronary artery. Etiology of the cases presented shows a myocardiac fibrosis with Schwachman's syndrome in one case, a coronary thrombosis secondary to a disseminated intravascular coagulation in a second case, and finally a generalized hypoplasia of coronary arteries. Hypoxia appears in these cases a factor acting in favour of myocardial ischemia. Diagnostic criteria of acute myocardial infarction are based on typical electrocardiogram and rise of isoenzymes of LDH and CPK-MB. Although rare, it is a diagnosis to be considered in cases of unknow cardiac insufficiency in newborns and infants.
