title: [The use of antithrombotic drugs in patients with chronic atrial fibrillation in a local health area].
abstract: BACKGROUND
  The objective of the study is to assess the degree of ambulatory use of prophylactic antithrombotic therapy in patients with chronic atrial fibrillation (CAF) in a county health area.
  
  
  METHODS
  A cross-sectional, prospective survey carried out in patients admitted at a community-hospital, detected 44 patients with CAF.
  
  
  RESULTS
  The inappropriateness of anti-thrombotic therapy (48%) was associated with no having a previous echocardiography (p < 0.004), not being controlled in a hospital (p < 0.02) and in patients without information on the cardioembolic risks (p < 0.0007).
  
  
  CONCLUSIONS
  The antithrombotic prophylaxis is scarcely used in patients affected by CAF in the county health area studied.
