Abstract

Background : Myocardial infarction is the most common cause of death for which the largest numbers of autopsies are done. Aim: A clinical study was done to determine those numerically smalle r but medico - legally more important cases in which some unnatural event like a road accident, is suspected to have been precipitated by acute myo cardial ischemia. The likel i hood of identifying an early infarct depends on the mechanism of the terminal cardi ac failure. Materials and method: A histochemical study on early ischemic changes in 100 hearts which can detect the healthy as well as the infarcted myocardium due to enzymatic changes in the myocardium, using haematox y lin and eosin as a routine stain an d acridine orange as a fluorescent stain, the latter can detect infarcts of even 2 hours of age to a ssess the actual age of the infarct and co n firmation of myocardial infarction as the cause of demise was done. Results: 37% of the cases were seen in the 6 th decade followed by 4 th&5 th decade, males were more affected, the male to female ratio being 11.5:1. 75% of the cases showed grade 2 and grade 3 stenosis of coronary artery. Majority of the hearts were within normal weight range showing absence of chro nicity of disease. Conclusion : Sudden death due to myocardial infarction is still the disease of middle age with increasing incid ence in younger age groups, acridine orange is the earliest detector of infarction and degree of stenosis is directly related with the age factor most common cause for that being ather o sclerosis .
