A year‑long autopsy study at AIIMS New Delhi found that more than half of sudden deaths occurred in adults under 45, many of whom appeared healthy until they collapsed at home or while travelling.
Study Overview
The cross‑sectional investigation, published in the Indian Journal of Medical Research as part of an ICMR project, examined 2,214 autopsies performed between May 2023 and April 2024. Of these, 180 cases (8.1 %) met the criteria for sudden death.
Age and Gender Profile
Young adults aged 18–45 accounted for 103 of the sudden‑death cases, representing 57.2 % of the total, with an average age of 33.6 years and a pronounced male predominance.
Leading Causes
Cardiovascular disease was the top cause, responsible for 42.6 % of sudden deaths among the young. Most victims had advanced coronary artery disease with severe blockages that had not been previously diagnosed.
Respiratory conditions such as pneumonia, tuberculosis and asphyxia accounted for just over one‑fifth of the deaths. More than one‑fifth remained unexplained despite comprehensive imaging, full autopsy and microscopic analysis, suggesting hidden electrical or genetic heart disorders.
Circumstances and Symptoms
The majority of fatalities occurred at home or during travel, frequently at night or in the early morning. Families most often reported a sudden loss of consciousness, followed by chest pain and breathlessness. Only a small number of the young decedents had known diabetes or hypertension.
Lifestyle Factors
Over half of the young adults who died suddenly were smokers or consumed alcohol, rates comparable to those observed in older age groups. The researchers found no significant association between sudden deaths and Covid‑19 infection or vaccination, noting high vaccination coverage across all ages.
Older Adults (46‑65)
In the 46‑65 age bracket, coronary artery disease accounted for more than 70 % of sudden deaths.
Potential Next Steps
Health authorities may consider expanding cardiovascular screening programs for people in their thirties and forties, especially those with smoking or alcohol habits. There could also be a push for genetic testing and family‑based cardiac evaluations to identify hidden electrical disorders that standard autopsies miss. Increased public awareness campaigns about silent heart disease might help intervene before fatal events occur.
Frequently Asked Questions
What proportion of sudden deaths involved people under 45?
Young adults aged 18–45 represented 57.2 % of the 180 sudden‑death cases identified in the study.
Which condition was the leading cause of sudden death among the young?
Cardiovascular disease accounted for 42.6 % of sudden deaths in the 18–45 age group, with most victims having advanced coronary artery disease.
Did the study find a link between Covid‑19 vaccination and sudden deaths?
No significant association was observed; vaccination coverage was high across all age groups.
