title: Usefulness of aortic knob width on chest radiography to predict central hemodynamics in patients with known or suspected coronary artery disease.
abstract: BACKGROUND
  Aortic knob width on chest radiography is independently related to cardiovascular disease. However, little is known about the correlation between aortic knob width and central hemodynamics.
  
  
  METHODS
  Central blood pressure was measured invasively with diagnostic catheter in 92 patients with known or suspected coronary artery disease.
  
  
  RESULTS
  Aortic knob width was positively associated with age (r = 0.42; p < 0.001), central systolic blood pressure (r = 0.35; p < 0.001) and central pulse pressure (r = 0.34; p < 0.001). Multivariate analysis showed that larger aortic knob width was independently related to the higher central systolic blood pressure.
  
  
  CONCLUSIONS
  Lager aortic knob width on chest radiography is an independent predictor of increase of central systolic blood pressure.
