Detection of C-9 as a Marker of Early Myocardial Infarction in Sudden Death Cases by Immunohistochemistry

Background: Autopsy changes in sudden cardiac death due to Acute Myocardial Infarction (MI), is a real challengefor Forensic Pathologist. Immuno-histochemistry has proved significant role identifying myocardial necrosis.Aim: To find the incidence of deaths ischemia, its among postmortem cases and therole C9 infarction by immuno-histochemical staining methods amongautopsy cases.Materials Methods: Study was conducted on 44 autopsy cases. Multiple tissue samples were collected fromthe heart other organs, processing paraffin blocks made Hemotoxylin Eosin (H&E)staining expression performed for C 9 marker out necrosis.Data analyzed using Statistical Package Social Sciences (SPSS-20) as descriptive statistics.Result: Common age group 51-60 years. 75% them found have co morbid conditions. Histopathologyfor showed 66% be positive.Conclusion: Complement factor used reliable identification early MI which donot show histopathological with haemotoxylin stains.
