title: [Atrial fibrillation and coronary disease].
abstract: OBJECTIVE
  To study the incidence of atrial fibrillation in patients (pts) with angiographic coronary artery disease and its relation with clinical and angiographic parameters.
  
  
  METHODS
  Retrospective study.
  
  
  METHODS
  Six hundreds consecutive pts, submitted to diagnostic coronary angiography, performed in Hemodynamic Laboratory of Santa Marta Hospital (from 88/04/03 to 90/05/04).
  
  
  METHODS
  From six hundreds pts were excluded 43 because they had also valvular heart disease and/or minimal coronary artery lesions. Two groups were considered: Group I-pts with atrial fibrillation (n = 7) and Group II-pts in sinus rhythm (n = 549). We evaluated the following parameters: age, sex, clinical history, basal ECG, cardiac enlargement in chest X-ray, angiographic score of LVF, left ventricular diastolic pressure (LVDP), ventricular aneurysm, mitral regurgitation and number of vessels disease.
  
  
  RESULTS
  We only found significant statistically differences between the two groups concerning the following parameters: a) age-mean age was superior in group I (Group I-64.2 +/- 8.2 versus 56.3 +/- 9.6), the number of pts older than 60 years in group I was 75% vs 33.8% in group II (p < 0.02); b) heart failure-the incidence was superior in group I, 37.5% vs 9% in group II (p < 0.03); c) cardiac enlargement in chest X-ray-75% pts of group I vs 22% of group II (p < 0.002); d) moderate to severe mitral regurgitation-25% of pts in group I vs 5% of pts of group II (p < 0.05).
  
  
  CONCLUSIONS
  Atrial fibrillation is an unusual rhythm in pts with angiographic coronary artery disease. Its presence is related with age, clinical evidence of heart failure, cardiac enlargement and moderate to severe mitral regurgitation.
