title: Trends in clinical profile and medical treatments of atrial fibrillation patients over the last 10 years.
abstract: OBJECTIVE
  We sought to define trends in AF prevalence and its medical management using recent data based on data from two cross-sectional studies performed in a European country in 1999 and 2009.
  
  
  METHODS
  CARDIOTENS 1999 and CARDIOTENS 2009 were two observational, cross-sectional, multicenter studies. Patients were recruited in from primary care and cardiology outpatient clinics. A total of 32 051 and 25 137 subjects were analyzed in the two studies, 1540 and 1524 of them, respectively, diagnosed with AF.
  
  
  RESULTS
  Over the course of the study period there was an increase in the prevalence of AF (from 4.8% to 6.1%), mainly due to the higher prevalence of AF in patients aged over 70 years (24.7% vs. 37.1%). Furthermore, patients with AF had a higher prevalence of hypertension (64.9% vs. 87.0%), diabetes (19.0% vs. 37.4%), heart failure (30.8% vs. 34.8%), coronary artery disease (23.0% vs. 25.8%) and previous stroke (1.5% vs. 8.9%). An overall increase in prescription of antithrombotic/antiplatelet therapy was observed (33.0% vs. 62.7% and 31.0% vs. 38.2% respectively); the difference observed in 1999 between prescription of oral anticoagulation by general practitioners and cardiologists was not seen in the later study. Differences in prescription of angiotensin-converting enzyme inhibitors (28.0% vs. 40.7%), angiotensin receptor blockers (10.0% vs. 40.0%), beta-blockers (14.0% vs. 41.5%) and calcium channel blockers (21.0% vs. 34.9%) were also identified.
  
  
  CONCLUSIONS
  The number of patients with AF and a higher risk for thromboembolic events increased over the last 10 years. More aggressive antithrombotic treatment has been observed, especially in older patients.
