In children with cardiomyopathy, the likelihood of sudden cardiac death may be predicted by cardiomyopathy phenotype, family history, severity of systolic dysfunction and degree of left ventricular hypertrophy, researchers reported in the Journal of the American College of Cardiology.
Researchers evaluated the incidence and risk factor for sudden cardiac death in 289 children younger than 10 years enrolled in the National Australian Childhood Cardiomyopathy Study (NACCS). The NACCS is an ongoing, longitudinal study assessing all children in Australia diagnosed with cardiomyopathy from 1987 to 1996. Each patient was categorized based on WHO classification: dilated cardiomyopathy, hypertrophic cardiomyopathy, restrictive cardiomyopathy or LV noncompaction.
