Inclusion criteria
Inclusion criteria: Among patients with CM, eligible subjects were confined to those who exhibited intrinsic abnormalities of the myocardium. The inclusion criteria for DCM were left ventricular dilation (left ventricular end diastolic diameter = 2 SD above normal for body-surface area), simultaneously reduced left ventricular systolic function (left ventricular ejection fraction (LVEF) = 2 SD below normal for age), and an absence of secondary causes of ventricular dilation. Diagnosis of HCM was based on left ventricular hypertrophy (a wall thickness = 2 SD above the normal population mean for body surface area), excluding defined hemodynamic causes such as congenital heart disease, hypertension, or exposure to drugs known to result in cardiac hypertrophy. Meanwhile, RCM patients included children who exhibited enlarged atria without ventricular dilatation in the absence of congenital, valvular, or pericardial disease. Finally, patients were diagnosed with LVNC as de?ned by the Jenni criteria.
Exclusion criteria
Exclusion criteria: Children with ventricular dilatation caused by secondary factors. Hypertrophic cardiomyopathy caused by congenital heart disease, hypertension, or exposure to drugs known to cause hypertrophy of the heart. Family members refuse to participate or do not cooperate.
