title: Relationship between Duke Treadmill Score and coronary artery lesion complexity.
abstract: OBJECTIVE
  The purpose of this study was to investigate the relationship between the Duke Treadmil Score (DTS) and coronary artery disease (CAD) complexity in patients with suspected coronary artery disease (CAD).
  
  
  METHODS
  Sixty five patients who had positive exercise testing for CAD were enrolled. Coronary angiography was performed and Syntax score (SxScore), a marker of CAD complexity, was determined. The relationship between DTC and SxScore then evaluated.
  
  
  RESULTS
  There was a strong negative correlation between DTS and SxScore (r = - 0.91, p < 0.001). In addition, patients with higher and intermediate risk as evaluated by DTS had increased SxScore compare to those that were low risk (23 ± 6, 6 ± 5 and 0 ± 0 respectively).
  
  
  CONCLUSIONS
  A strong negative correlation was seen between DTS and coronary lesion complexity. By assessing DTS important information about coronary artery lesion complexity can be obtained before invasive coronary angiography.
