Functional Class in Children with Idiopathic Dilated Cardiomyopathy.A pilot Study

View Article: PubMed Central - PubMed

ABSTRACT

Background: Idiopathic dilated cardiomyopathy (IDCM), most common cardiac cause ofpediatric deaths, mortality descriptor: a low left ventricular ejectionfraction (LVEF) and low functional capacity (FC). FC is never self reportedby children.

Objective: The aims of this study were (i) To evaluate whether functionalclassifications according to the children, parents and medical staff wereassociated. (iv) To evaluate whether there was correlation betweenVO2 max and Weber's classification.

Method: Prepubertal children with IDCM and HF (by previous IDCM and preserved LVEF)were selected, evaluated and compared. All children were assessed bytesting, CPET and functional class classification.

Results: Chi-square test showed association between a CFm and CFp (1, n = 31) = 20.6;p = 0.002. There was no significant association between CFp and CFc (1, n =31) = 6.7; p = 0.4. CFm and CFc were not associated as well (1, n = 31) =1.7; p = 0.8. Weber's classification was associated to CFm (1, n = 19) =11.8; p = 0.003, to CFp (1, n = 19) = 20.4; p = 0.0001and CFc (1, n = 19) =6.4; p = 0.04).

Conclusion: Drawing were helpful for children's self NYHA classification, which wereassociated to Weber's stratification.

Mentions: According to the peak VO2 found in CPET, Weber classification wassignificantly associated with the three functional classes described in this study,using the χ2 test: Weber classification and FCm (1, n = 19) =11.8; p = 0.003; Weber classification and FCp (1, n = 19) = 20.4; p = 0.0001; Weberclassification and FCc (1, n = 19) = 6.4; p = 0.04.
