Abstract :

Background: Acute atrial fiillation is an important and frequent complicationST elevation myocardial Infarction.Atrial fiillation is an independent predictor of both short termand long term mortality. The study addresses the question whether the reperfusion strategy and reperfusion as assessed by ST resolution affect the development of AF as a complication of STEMI. Materials and methods:It was a single center, prospective cohort study, conducted from October 2014 to January 2016. The patients were divided into three groups1. Those with AF at admission. 2. those developing AF within 24 hours of admission. 3. Those developing AF after 24 hours and till discharge. The patient’s clinical and echocardiographic profile were documented. They were followed up for development of complications. Results:49 patients had AF within 24 hours of admission and 10 patients developed AF after 24 hours. There was no significant difference between the rates and mode(primary PCI and fiinolysis) of revascularization in patients developing AF and those without AF. The total ischemic period prior to revascularization did no,ST t influence the development of AF. The post–reperfusion ST segment resolution was not different in the two groups.
