title: Pediatric cardiomyopathies over the last decade: a retrospective observational epidemiology study in a tertiary institute, Egypt.
abstract: BACKGROUND
  Pediatric cardiomyopathy (CM) is a rare, life-threatening disorder of unknown etiology. Data on CM in Egypt are scarce as there is no national registry. This study was an effort to understand the demographic features, clinical presentation, and frequency of different types of childhood CM in Egypt.
  
  
  METHODS
  Medical files of all children diagnosed with CM in the last decade (1997-2007) and referred to the Pediatric Cardiology Clinic at Ain Shams University, Children's Hospital (Cairo, Egypt), were reviewed. This study included 124 (6.6%) cardiomyopathic patient files from a total of 1876 cardiac patients that were followed up at the Pediatric Cardiology Clinic during the 10-year study period.
  
  
  RESULTS
  In the last decade (1997-2007), children with CM represented 6.6% of all children with cardiovascular diseases followed at the Pediatric Cardiology Clinic; 73 were boys (58.9%) and 51 were girls (41.1%), with a mean age of 3.82±3.99 years. Parental consanguinity was positive in 19.4% of patients and a history of preceding viral infection was present in one patient (0.8%). Eight patients had a similarly affected sibling (6.5%).
  
  
  CONCLUSIONS
  Data on CM in Egypt are scarce, highlighting the urgent need for a national registry for CM (a) to allow more accurate assessment of the size of this problem, especially in children; (b) to minimize loss of follow-up data when patients move from one region to another; and (c) to allow screening of family members of a proband case.
