title: Sudden cardiac death in 15-35-year olds in Sweden during 1992-99.
abstract: OBJECTIVE
  To study the incidence, pathogenesis and symptoms preceding sudden cardiovascular death amongst 15-35-year olds without substance abuse in Sweden during 1992-99.
  
  
  METHODS
  This was a register study of a national database of forensic medicine, Rattsbase. Clinical details were obtained from forensic, police and medical records and from interviews with family members.
  
  
  METHODS
  The whole nation of Sweden.
  
  
  METHODS
  Individuals having suffered a sudden cardiac death.
  
  
  RESULTS
  We found 181 cases of sudden cardiovascular death in a nationwide database, Rattsbase, in 15-35-year olds, of which 132 (73%) were male and 49 (27%) were female, and a rather stable incidence of 0.93 per 100,000 per year. Preceding symptoms were seen in half of the cases. The most common forensic diagnoses were: no structural abnormality (21.0%), coronary atherosclerosis (17.7%), dilated cardiomyopathy (12.2%), hypertrophic cardiomyopathy (10.5%) and myocarditis (10.5%).
  
  
  CONCLUSIONS
  Sudden cardiovascular death was uncommon in the young, but the incidence was not decreasing. Postmortem diagnoses were often difficult to establish. There was a high frequency of structurally normal hearts. Because premortal cardiac-related symptoms are relatively common and treatment methods are developing, we should learn to recognize early symptoms of heart disease. To identify individuals at risk, further studies of preceding symptoms, life-style factors and electrocardiogram (ECG) changes are needed.
