In patients with acute myocardial infarction, the presence of permanent bundle branch block, particularly LBBB with anterior wall MI, is associated with high rates of complications and in-hospital mortality.
The occurrence of bundle branch block in acute myocardial infarction is important because it indicates that infarction may be extensive and may result in cardiac failure or death; however, the presence of bundle branch block is also important because it indicates seriously jeopardized AV conduction which could result in sudden extremely slow heart rates or asystolic arrest. The aim of the study was to study clinical characteristics in patients of acute coronary syndrome with bundle branch block and to assess the association of bundle branch block with major cardiovascular events or complications and to determine in-hospital mortality .The study was done on patients of acute myocardial infarction (MI) admitted between April 2012 to Nov. 13 in the coronary unit of J.A.H., Gwalior .
