Atrial Fibrillation in Acute Myocardial Infarction
Journal Title: Nepalese Heart Journal - Year 2015, Vol 12, Issue 1
Abstract
background and aim: New-onset atrial fibrillation frequently complicates acute myocardial infarction. The incidence ranges from 6 - 21% “1â€.We aim to determine the incidence of atrial fibrillation in the setting of acute myocardial infarction. Methods: This was a single center prospective study, conducted in the coronary care unit of Saint-Petersburg Pokrovskaya city hospital, Russia, during the period, June 2013 to June 2014. Sixty consecutive patients of acute myocardial infarction with atrial fibrillation were included in this study. Onset, duration, and mode of termination of atrial fibrillation, clinical factors associated with its presentation and its relation with patient outcome were evaluated. results: Among the 60 patients 33 (55%) had inferior wall myocardial infarction and 27 (45%) patients had anterior wall myocardial infarction. In patients with inferior wall myocardial infarction the onset of atrial fibrillation occurred within 24 hours in 30 (91%) patients, after 24 hour in 3 (9%) patients. The episode lasted for less than 24 hours in 12 (36%), and more than 24 hours in 21 (64%) patients. In anterior wall myocardial infarction atrial fibrillation occurred within 24 hours in 2 (7%) patients, on the second day in 25 (93%). The episode lasted less than 24 hours in 3 (11%), 48 hours in (85%), 72 hours in 1 (4%) patients. There was a significant difference in the onset and duration of atrial fibrillation in relation to the location of infarction (P < 0.0001). Anterior wall myocardial infarction was associated with late onset of atrial fibrillation, increased frequency of heart failure and higher CCU mortality. Conclusion: The onset of atrial fibrillation in anterior wall myocardial infarction occurred later and lasted longer in comparison to inferior wall myocardial infarction. Increased incidence of heart failure and higher CCU mortality was associated with anterior wall myocardial infarction.
