Patterns of Cardiac Rupture in Blunt Cardiac Injuries and Coronary Artery Disease: A Retrospective Autopsy Study

Abstract

Cardiac rupture is the most severe form of blunt chest injury and coronary artery disease and that leads to a devasting medical emergency, Becker and colleagues identified three types of myocardial rupture, in Govt Stanley medical college and hospital, 2017-2019 cases with the postmortem findings and hospital records suggestive of cardiac rupture, were studied retrospectively and the Information were collected and analyzed. In the retrospective study population 426 cases had blunt chest trauma in that cardiac rupture seen in 28 cases amongst Becker type I rupture seen in 26 cases and type II rupture seen in 2 cases. Amongst 792 cases of coronary artery disease with myocardial infarction 13 cases had cardiac rupture in that Beckers type I rupture noted in 5 cases and type II were noted in 8 cases. Beckers type III rupture cases were not presented in the retrospective study population. Male cases were predominantly seen in both blunt chest injuries and in coronary artery disease and most of the cases were in the age group of 31-60 years. Among blunt chest injury traffic accidents were most common cause for cardiac rupture and in coronary artery disease left anterior descending artery occlusion was the most common cause for cardiac rupture, In the present study it has been proved that a diseased heart is more susceptible to traumatic injury than a normal one. The diseased heart is more likely to rupture at the fragile myocardium sites ,The presence of fatal cardiac trauma in head on collision cases emphasizes the utility of safety belts while driving. The present study is undertaken to identify the exact pathophysiology and bio mechanism of cardiac rupture
