ABSTRACT
Objective To research the risk factors of new-onset atrial fibrillation (AF) during hospitalization in patients with acute myocardial infarction.Methods Five hundred and one patients first diagnosed with acute ST-segment elevation myocardial infarction who accepted primary coronary intervention from January 2012 to May 2014 in the Second Hospital of Tianjin Medical University were selected.These patients were divided into non-AF group and new-onset AF group depending on whether happened new-onset AF during hospitalization.Data of the patients in acute myocardial infarction complicated with new-onset atrial fibrillation were collected.Univariate and multivariate logistic regression analysis were used to determine the predictors of new-onset AF.Results AF occurred in 49 cases of the 501 (9.8%) patients diagnosed as acute myocardial infarction.Logistic regression analysis showed that admission heart rate(OR =1.019,95%CI1.004-1.034,P =0.012),left atrial diameter (OR =1.086,95% CI1.021-1.156,P =0.009),previous stroke (OR =2.060,95% CI1.029-4.123,P =0.041) were independent risk factors for new-onset AF in acute myocardial infarction.Use of β-blockers before coronary intervention treatment can reduce the risk of new-onset atrial fibrillation(OR=0.222,95%CI0.064-0.768,P=0.017).Conclusion Admission heart rate and left atrial diameter are independent predictors of new-onset atrial fibrillation,and β-blockers in early stage can effectively reduce the incidence of atrial fibrillation.
