title: [A study on the recurrence of ischemic stroke in nonvalvular atrial fibrillation].
abstract: OBJECTIVE
  To study the recurrence of ischemic stroke in patient with nonvalvular atrial fibrillation (NVAF) and to determine the recurrence related factors of ischemic stroke in patients with NVAF.
  
  
  METHODS
  The clinical data of 386 NVAF patients with ischemic stroke treated in our hospital from January 1992 to February 2002 were included in this study. The basic clinical information of each patient was recorded. Analysis of recurrence and recurrence related factors of ischemic stroke in patients with NVAF was conducted.
  
  
  RESULTS
  Overall the 10-year recurrence rate of ischemic stroke in patients with NVAF was 34%. Hypertension, diabetes mellitus, transient ischemic attack (TIA), hyperlipemia and mural thrombus in left atrium were significantly correlated with the recurrence rate by univariate Cox proportional hazards regression analysis; but aspirin therapy, warfarin therapy and hypertension control were protective factors for the recurrence of ischemic stroke in patients with NVAF. Multivariate Cox proportional hazards regression analysis revealed that hypertension, TIA and mural thrombus in left atrium were independent recurrence related factors for ischemic stroke in patients with NVAF; but aspirin therapy and warfarin therapy were protective factors for the recurrence.
  
  
  CONCLUSIONS
  Hypertension, TIA and mural thrombus in left atrium were independent recurrence related factors for ischemic stroke in patient with NVAF; but aspirin therapy and warfarin therapy were protective factors for the recurrence.
