OBJECTIVE
The evaluation of the clinical aspects of the dilated cardiomyopathy (DCM) in infants and children regarding, mainly, to the evolution and prognostic of this disease.
METHODS
38 patients divided in two groups: A) 22 infants till 22 (11.60 +/- 6.50) months of age, 15 female, and B) 15 children of 2 to 12 years of age (5.23 +/- 3.13) the majority males (10). A retrospective study was carried out based on the data from the patients's records. It was performed, in all the cases, a clinical, electrocardiographic, echocardiographic (M module and two dimensional echocardiography) and radiologic evaluation.
RESULTS
The dyspnea on exercise (included sucking) was the predominant symptom in 15 (65.22%) patients of the A group and 10 (66.67%) of the B group followed by perilabial cyanosis in 7 (30.43%) and 6 (40%) patients, respectively. In the A group the clinical diagnostic hypothesis was inspecific myocarditis (IM) in 12 (52.17%), endocardial fibroelastosis (EFE), in 8 (34.79%), and "idiopathic" dilated cardiomyopathy (IDCM) in 3 (13.04%). In the B group to the diagnostic conclusion of myocarditis was made in 10 patients (66.67%)--5 of them IM--EFE in 3 (20%); and IDCM in 2 (13.33%). The average time of evolution was 5.48 months in the A group and 18.56 in the B group. In the A group the evolution was excellent in 3 (3.04%), good in 10 (43.46%), stable in 2 (8.70%) and bad in 1 (4.35%). In the B group, excellent in 8 (53.33%), good in 2 (20%) stable in 1 (6.67%). No bad evolution in this group. There was a decrease in the A group (4.34%); 6 patients in this group (26.09%) and 3 (20%) of the B group interrupt the follow-up.
CONCLUSIONS
1) The prognosis of infants with DCM including those with the diagnostic hypothesis of EFE seems to be less adverse than it could be supposed to be; 2) the prognostic in children with the diagnosis of DCM established above 2 years of age seems to be good; 3) the differential clinical diagnosis between EFE and IM is difficult and with no accuracy; 4) it is possible that the IM could be more prevalent in infants till 6 months of age than we suppose it was.
