Introduction: Cardiac diseases emerge as the primary culprits behind sudden and unexplained deaths. Morphological evaluation through autopsy is invaluable in establishing the prevalence of cardiac lesions and coronary atherosclerosis within the general population. It provides healthcare researchers with valuable insights to develop preventive measures and early detection strategies crucial for improving survival rates.
Aim: To estimate the prevalence of cardiac lesions in postmortem specimens of the heart from autopsies of sudden and unexplained deaths.
Materials and Methods: The present cross-sectional study was conducted in the Department of Pathology, Government Medical College (a public sector hospital), Cochin, Kerala, India, from January to December 2021 on 140 specimens of the heart. Medicolegal autopsies were performed in the Department of Forensic Medicine, with specimens forwarded to the Pathology Department for histopathological examination. Hearts dissected by the modified Virchow’s method were examined for gross pathology in the cardiac wall, chambers, valves, coronaries and aorta. Microscopy findings were documented and the grading of coronary atherosclerosis was done using the Modified American Heart Association (AHA) criteria. Proportions were analysed from the compiled data using a Chi-square test. Statistical analysis was done using Statistical Package for the Social Sciences (SPSS) software version 21.0 software.
Results: In the study encompassing 140 adult autopsies, the mean age of the study population was 45.98 with a Standard Deviation (SD) of 15.82 years and the male to female ratio was 3.5:1. The prevalence of cardiac lesions was as follows: coronary artery atherosclerosis (80.70%), Ischaemic Heart Disease (IHD) (44.28%), cardiac hypertrophy and hypertension (10%), pericarditis (6.42%) and myocarditis (3.50%). The male-to-female ratio for coronary atherosclerosis was 4.4:1, with triple vessel disease observed in 42.90% of cases. Atherosclerosis severity grades included early non atheromatous lesions (19.3%), Pathological Intimal Thickening (PIT) (23.6%), and advanced atherosclerotic lesions (37.80%). Among cases associated with Coronavirus Disease 2019 (COVID-19)-related deaths (10.7%), changes noted included myocarditis, microhaemorrhages, oedema, capillary dilatation, fibrin deposition and inflammatory infiltrates.
Conclusion: The present study revealed a high prevalence of coronary atherosclerosis affecting all three vessels, particularly among the younger population. This underscores the significance of screening for cardiovascular risk factors and implementing preventive measures from an early age.
