Cardiovascular diseases remain the predominant cause of sudden natural death, particularly among middle-aged males with a history of smoking and alcohol use.

Key Points

  • The study aims to investigate the pattern and causes of sudden natural deaths (SND) in a tertiary care setting.
  • Conducted a prospective study over 36 months at a tertiary care hospital.
  • Analyzed medico-legal autopsy cases to gather data on sudden natural deaths.
  • Collected detailed histories and autopsy findings, then tabulated the results using frequency and percentage.
  • SNDs comprised 13.3% of 5,260 total autopsies, with 700 cases identified.
  • The most affected age group was 31 to 50 years, predominantly males at 85.1%.
  • 55% of SND cases were linked to cardiovascular diseases, followed by 26% to respiratory diseases.
  • Smoking affected 65.1% of cases and alcohol consumption was noted in 69.8%.
