Retrospective Analysis Of Post Operative AF 101 Hospitalized Patients Of Xinjiang Medical University First Affiliated Hospital

Objective:Atrial fibrillation(AF)is a common arrhythmia associated with increased cardiovascular morbidity and mortality.This study was undertaken to analyze the cardiac surgical department post operative Atrial frbrillation cases from 2001 to 2006. Methods:Retrospective analysis of hospital records were taken from patients with AF, discharged from cardiac surgical department Jan 1 2001 to June 31 2006.Results:1)A total of 101 cases with AF were enrolled.Mean age was 44.8 years old.The cases distribution progressively decrease with age.Among them,96 cases have ECG documents,5 cases have DCG documents.Han and minority race have no significant difference in AF type,age,stroke and left atrium thrombus.2)The causes and associated conditions of AF:rheumatic valvular disease 93.1%,hypertension 3.0%,congenital 3.9%In this group,97 cases have left atrium size＞40mm,twenty patients have left atrium thrombes.3)Types of AF:Permanent AF(20.8%),paroxysmal(2.0%)and persistent AF were(77.2%).4)The prevalence of stroke in this group was 10.1%.85% of our patients received antithrombotic therapy.Among them,4.9%use antiplatelets, 67.4%use anticoagulants,and 12.9%combined and 14.8%no medication.Patients with arrticoagulants combined antiplatelets showed no incidence of stroke.Conclusion: Incidence of atrial fibrillation in xinjiang is highly associated with RHD.Anticogulation therapy with INR＞2 reduce the complication of stroke in AF patients,85%patients received antithrombotic therapy.Anticoagulant treatments with INR＜2 have shown less efficacy in reducing Post operative Atrial fibrillation complications like stroke.As patients taking Anticoagulation in addition to Antiplatelet have shown no incidence of stroke.Han and minority race have difference in AF type,mean Age,no difference in stroke and left atrium thrombus complication.No Post operative atrial fibrillation incidence after CABG between 2002-2006.Pos operative AF Restoration to sinus have Mean Age＜39,Mean LA＜52.and normal ventricular EF.
