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

Abstract

BackgroundIdiopathic dilated cardiomyopathy (IDCM), most common cardiac cause of pediatric deaths, mortality descriptor: a low left ventricular ejection fraction (LVEF) and low functional capacity (FC). FC is never self reported by children.ObjectiveThe aims of this study were (i) To evaluate whether functional classifications according to the children, parents and medical staff were associated. (iv) To evaluate whether there was correlation between VO2 max and Weber's classification.MethodPrepubertal children with IDCM and HF (by previous IDCM and preserved LVEF) were selected, evaluated and compared. All children were assessed by testing, CPET and functional class classification.ResultsChi-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).ConclusionDrawing were helpful for children's self NYHA classification, which were associated to Weber's stratification.

Dilated cardiomyopathy in spider-monkey (Ateles chamek, Humboldt, 1812): case report

“…Most cases of DCM are due to primary or idiopathic causes (Tavares et al, 2016). This disease occurs after changes in myocardial cells, induced by inflammation, toxins, lack of essential cellular nutrients and/or genetic metabolic dysfunction (Ardila et al, 2009).…”

Prognosis of Dilated Cardiomyopathy with Severe Heart Failure according to Functional Classification Scales in Childhood

“…Tavares et al 22 developed a version of the NYHA classification for the symptoms in the pediatric range and created a graphical representation of the four functional classes. Through this visual method, the perception of the children and their caregivers can be obtained, in addition to the categorization carried out by the medical team.…”
