Indicações do teste ergométrico em crianças e adolescentes

Abstract

The exercise test (ET) is a low-risk procedure that presents extremely rare complications, especially among pediatric age populations. In this reviewing, the main ET indications in children and adolescents (age up to 19 years) are presented as a method of diagnostic, prognostic and functional evaluation in several situations: evaluation of the physical capacity, evaluation of symptoms related to exercise, evaluation of clinical and surgical treatments in patients with cardiomyopathies, congenital and valvar cardiopathies, asthmatic patients and pre-participation in physical activities programs, among others.Adult patients have as most frequent indication of ET the search for diagnostic information, when intermediate probability of significant coronary arterial disease occurs in the absence of significant alterations of the ECG in rest (1) . The ischemic disease is rare among young populations, what shows a significant difference in indication and interpretation and results in low risk in the ET routine in the pediatric age population. The complications are extremely rare even when ET is performed in children with congenital cardiopathies and arrhythmias. The ET applications in young individuals are mainly related to the measure of the physical capacity, evaluation of known cardiac abnormalities and evaluation of symptoms related to exercise (2) .

Função cardiovascular de crianças obesas e eutróficas de 9 a 12 anos

“…A dificuldade atual, de acordo com alguns estudos, é que a obesidade infantil está inversamente relacionada com a prática de atividade física (OLIVEIRA et al, 2003). Em 2001 foram avaliados 1.253 estudantes com média de idade de 12,4 ±2,9 anos, da rede de ensino da cidade de Maceió e a incidência de sedentarismo foi de 93,5% (SILVA et al, 2004). Esses dados alertam para o comprometimento cada vez maior do sistema cardiovascular pelo fato de a obesidade afetar a função e estrutura cardíaca e ocasionar efeitos adversos na hemodinâmica (LAVIE;MILANI;VENTURA, 2009).…”
