title: An autopsy study of sudden cardiac death.
abstract: OBJECTIVE
  To determine the cause of sudden cardiac death and observe the morphological changes in the heart after death.
  
  
  METHODS
  A cross sectional survey of 66 cases was carried out at Armed Forces Institute of Pathology (AFIP) Rawalpindi from 1992 to 1994. A detailed autopsy including external and internal postmortem examination was done. Representative sections were taken for histopathological examination and some viscera were sent to Chemical Examiner at Lahore for chemical analysis.
  
  
  RESULTS
  All the cases were male with age range from 21 to 58 years. These cases died within 60 minutes with or without onset of symptoms. Fifty two cases revealed mild to severe atherosclerosis. Coronary occlusion with thrombosis was seen in 37 cases whereas 9 cases showed critical narrowing without evidence of thrombosis. Five showed both symmetric and asymmetric hypertrophy. Changes in conduction system of the heart were seen in 4 individuals. Myocarditis was noted in 2 cases only. The cause of death could not be determined in 3 cases.
  
  
  CONCLUSIONS
  Majority of the cases died of coronary atherosclerosis whereas 17% cases revealed hypertrophic cardiomyopathy, changes in conduction system and myocarditis and 4% cases were undetermined. A detailed and thorough postmortem examination is mandatory to ascertain the cause of sudden cardiac death.
