INTRODUCTION : Cardiovascular disease (including coronary artery disease, stroke and peripheral vascular disease) is no.1 cause of worldwide mortality, with about 80% of burden occurring in developing countries. Sudden cardiac death is dened as unexpected death from cardiac causes either without symptoms or within 1-24 hours of onset of symptoms(1). The common cause of sudden cardiac death is ischaemic heart disease. Non ischaemic sudden cardiac death occurs in hypertrophic obstructive cardiomyopathy and in severe left ventricular hypertrophy(2). The purpose of this study will be to determine the causes of sudden death and observe the spectrum of morphological and histopathological changes in heart after sudden death. MATERIALS AND METHODS: This autopsy study was conducted on 121 cases of sudden death over a period extending from January 2019 to August 2020 in autopsy section of Pathology department of BJGMC, Pune. In this autopsy study hearts of patients with a history of sudden death were evaluated for histological and morphological changes. Each heart was grossed adopting the inow outow method and short axis method. Staining solutions used were Solution A: Alum Hematoxylin and Solution B: 1% Eosin Y. OBSERVATIONS : 50 (41.32%) cases out of 121 cases had coronary artery disease along with myocardial infarction of which 43 cases were males and 7 cases were females. No cardiac aetiology was found in 23.96% cases. Coronary artery disease was independently seen in 14.87% cases. Left ventricular concentric hypertrophy was noted in 4.13% cases. Myocardial infarction independently was noted in 3.30%cases, Myocarditis in 2.47% cases, myocarditis with pericarditis in 1.65% cases, HOCM, lipoma, mitral stenosis, pericarditis, septic infarct, secondaries of adenocarcinoma, early vegetation and small vessel disease in 0.82% cases. Calcic aortic stenosis was demonstrated in 1 case. Brown atrophy was demonstrated in 1 case. DISCUSSION : Out of 69 cases of coronary artery disease calcication was commonly seen in 34(49.27%) cases. 47(82.45%) (M-39,l F-8) out of 57 cases of myocardial infarction demonstrated chronic or old infarct. Single vessel involvement was most common in which left anterior descending coronary artery was signicantly involved in 68.75 % cases. Posterior wall was most commonly involved by myocardial infarction which included posterior, posteroseptal, and posterolateral infarcts. |
