Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2017, Vol 16, Issue 1
Abstract
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 . Informed and written consent was taken from all patients before enrolling this work. The inclusion criteria included those patients admitted within 48 hrs of onset of symptoms with bundle branch block on the admission ECG and new onset bundle branch block during hospital stay Study excluded patients with previous history of documented bundle branch block. The statistically significant findings of the study included more common incidence of anterior wall infarct over inferior, right bundle branch block over left bundle branch block ,right bundle branch block in males and in patients of age less than 60 years .Mortality was higher in patients with anterior wall MI associated with finding of Left bundle branch block .
