[Myocardial infarct in children. The anatomicoclinical aspects]

Nine cases of myocardial infarction in the newborns (8 cases aged between 7 days and 6 months) and infants (1 case aged 12 years and 6 months) were followed up for 15 years. The etiology was different: mediocalcosis of the coronaries, congenital abnormalities of the heart marked hypertrophy of left ventricular myocardium (endocardial fibroelastosis or nonobstructive hypertrophic cardiomyopathy) severe hypoxia (severe acute bronchopneumopathies), and AAR, cardioarticular form, with multiple attacks in the infant. The ECG aspects were not specific in most children and clinically the prevailing finding was severe decompensated cardiac failure. The main etiologies and the inducing mechanisms of myocardial infarction in children are presented.
