Abstract:
Objective To discuss the prognostic impact of atrial fibrillation (AF) in patients with chronic heart failure(CHF).Methods From January,2005 through December,2006 we studied 461 patients with a discharge diagnosis of CHF.Patients were divided by baseline rhythm in sinus rhythm(SR) or AF groups.The main endpoints were all cause death within 3 years and readmission to the hospital for heart failure.Results AF group were more likely to be older and female and to have a history of valvular disease and have a higher left ventricular ejection fraction (LVEF).However,SR group were more likely to have a history of ischemic heart disease.During 3 year follow-up,the main endpoints was higher in AF group than in those with SR group (P ＜0.01).After adjusting for other covariables,AF and age were related to increased the risk of main endpoints during 3 years follow-up (RR =1.311,95％ CI:1.002-1.715,P ＜0.05 ; RR =1.014,95％ CI:1.004-1.024,P ＜ 0.01).Conclusion AF and age were the main risk factors of increased adverse forward prognosis in patients with CHF.
