Official Title: Cardiac Murmurs in Children: Predictive Value of Cardiac Markers

Brief Summary:

Heart murmurs are commonly discovered in young children during clinical encounters in general practice. Heart murmurs might signal a structural cardiac disease that need to be treated, such as atrial septal defect. Thus, children with heart murmurs are routinely referred to comprehensive cardiac examination at a paediatric hospital department featuring echocardiography ('gold standard'). However, the great majority of such murmurs are innocent or physiological; ie., they do not represent a cardiac disorder. The prevalence of such innocent murmurs during routine random auscultation is estimated at 30 %.

It would be advantageous if patients with a heart disease to a greater extent could be identified at the general practitioners' office:

  • Healthy children would not be exposed to comprehensive cardiac examination
  • The burden on the family would subside.
  • Scarce medical resources in highly specialized departments would be better allocated, to the benefit of patients with real heart disease.

The primary aim of this study is to establish the predictive value of cardiac markers in children with heart murmurs. Secondary aims are a) To do a pilot study of pediatric cardiac ultrasound examination in general practice; b) To establish age-adjusted reference range for cardiac markers in children, and c) To explore aspects of cardiovascular physiology in children.

The investigators will include a total of 500 children aged 4 weeks to 10 years who is consecutively referred to the Dept. of Paediatrics, Akershus University Hospital, for assessment of heart murmurs. All participants will be subjected to clinical examination, symptom asses
