There is a scarcity of comprehensive data on the prevalence, contributing factors, and underlying causes in the Indian context. This study aims to identify demographic patterns, key cardiac pathologies, and associated lifestyle factors, in cases of sudden cardiac death in the South Indian population and to provide insights for public health interventions.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Materials and Methods:<\/jats:title>\n                    <jats:p>This single-center cross-sectional study was conducted in a government tertiary care center in South India, involving autopsies registered from 2017\u20132019 for identification of the cause of death. Demographic data, relevant medical history, and events preceding death were collected from the relatives of the victims and medical records. Patients with a history of trauma, positive toxicological findings, and pathological findings in other organs were excluded from the study. Detailed gross and microscopic examinations of heart samples were performed to assess coronary and myocardial pathologies.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>The mean age was 48 years, with a male preponderance. Lifestyle factors, including a lack of physical activity, smoking, and alcohol consumption, were the critical factors contributing to sudden death in the younger age group. coronary artery disease (CAD), predominantly acute Myocardial Infarction (MI), was identified as the leading cause of death. Surprisingly, 41% of the patients with histopathological changes of MI in myocardium showed less than severe stenosis in the coronaries.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Coronary artery disease, particularly acute MI, is the primary cause of sudden cardiac death in South India, with lifestyle factors such as smoking, physical inactivity, and alcohol abuse as significant contributors. Higher coronary atherosclerotic plaque burden is associated with major adverse cardiac events. This study underscores the need for molecular autopsies, lifestyle-focused interventions, early CAD detection, and Cardio-pulmonary resuscitation (CPR) training. Establishing a sudden cardiac death (SCD) registry and enhancing resuscitation measures are crucial for reducing its impact.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.4103\/jfmpc.jfmpc_215_25","type":"journal-article","created":{"date-parts":[[2025,10,29]],"date-time":"2025-10-29T13:01:43Z","timestamp":1761742903000},"page":"4292-4297","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":0,"title":["Insights into Pre-COVID sudden cardiac deaths-: An autopsy study in South India"],"prefix":"10.4103","volume":"14","author":[{"given":"Dharma Saranya","family":"Gurusamy","sequence":"first","affiliation":[{"name":"Department of Pathology, Government Medical College Virudhunagar, Virudhunagar, Tamil Nadu, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gopika","family":"Venkataraju","sequence":"additional","affiliation":[{"name":"Department of Pathology, Thenkasi Government Hospital, Thenkasi, Tamil Nadu, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vasuki","family":"Selvamurugesan","sequence":"additional","affiliation":[{"name":"Department of Pathology, Kanyakumari Government Medical College, Kanyakumari, Tamil Nadu, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shantaraman","family":"Kalyanaraman","sequence":"additional","affiliation":[{"name":"Dean, Madras Medical College, Chennai, Tamil Nadu, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2025,10,31]]},"reference":[{"key":"R2-20251105","doi-asserted-by":"crossref","first-page":"380","DOI":"10.1016\/S0002-8703(05)80031-6","article-title":"Geographic variation in sudden coronary death","volume":"119","author":"Gillum","year":"1990","journal-title":"Am Heart J"},{"key":"R3-20251105","doi-asserted-by":"crossref","first-page":"163","DOI":"10.1016\/j.ijcard.2010.09.016","article-title":"Contribution of sudden cardiac death to total mortality in India-a population based study","volume":"154","author":"Rao","year":"2012","journal-title":"Int J Cardiol"},{"key":"R4-20251105","doi-asserted-by":"crossref","first-page":"687","DOI":"10.1007\/s00428-020-02949-8","article-title":"Autopsy examination in sudden cardiac death: A current perspective on behalf of the Association for European Cardiovascular Pathology","volume":"478","author":"Banner","year":"2021","journal-title":"Virchows Arch"},{"key":"R5-20251105","doi-asserted-by":"crossref","first-page":"691","DOI":"10.1007\/s00428-017-2221-0","article-title":"Guidelines for autopsy investigation of sudden cardiac death: 2017 update from the Association for European Cardiovascular Pathology","volume":"471","author":"Basso","year":"2017","journal-title":"Virchows Arch"},{"key":"R6-20251105","first-page":"7","article-title":"Cardiac channelopathies and sudden death: Recent clinical and genetic advances","volume":"6","author":"Fern\u00e1ndez-Falgueras","year":"2017","journal-title":"Biology (Basel)"},{"key":"R8-20251105","doi-asserted-by":"crossref","first-page":"126","DOI":"10.1016\/S0025-6196(12)64945-3","article-title":"Age-related changes in normal human hearts during the first 10 decades of life.
