title: Prediction of radial artery diameter in candidates for transradial coronary angiography: Is occupation a factor?
abstract: OBJECTIVE
  Transradial approach (TRA) for coronary angiography is a popular alternative approach to transfemoral coronary angiography due to the infrequent occurrence of access site complications such as bleeding, hematoma and pseudoaneursym formation. However, not all patients are suitable for TRA. This study aimed to determine the predictors of radial artery diameter in patients who are candidates for TRA.
  
  
  METHODS
  The study included 222 consecutive patients who underwent TRA due to suspected stable coronary artery disease. Radial artery diameter was evaluated prior to the procedure using B-mode ultrasonography.
  
  
  RESULTS
  Radial artery diameter was correlated with wrist circumference (r=0.539, p<0.001), height (r=0.258, p<0.001), weight (r=0.237, p<0.001), body mass index (r=0.167, p=0.013), shoe size (r=0.559, p<0.001), and pulse pressure (r=-0.161, p=0.016). The right radial artery was larger in men than in women (2.73±0.39 mm vs. 2.15±0.35 mm, p<0.001), and smaller in patients with sedentary office work than in physically active outdoor workers (2.42±0.45 mm vs. 2.81±0.37 mm, p<0.001). Wrist circumference (b=0.044, p<0.001, confidence interval (CI) 95%= 0.025-0.062), shoe size (b=0.075, p=<0.001, CI 95%=0.039-0.112) and occupation (b=0.228, p<0.001, CI 95%=0.138-0.318) were the independent predictors of radial artery diameter in regression analysis.
  
  
  CONCLUSIONS
  In addition to shoe size and wrist circumference, occupation may be an important predictor of radial artery diameter, and it should be evaluated with other clinical parameters in the prediction of radial artery diameter.
