By multivarariate analysis, Euroscore, and T-shapebifurcation lesion were independant predictors of death.

However, independant predictors of cardiac death were Euroscore and creatinine clairance suggesting that there is probably confounding factors.

  • Coronary tree has a extremely complex three-dimensional fractal geometry which involves major curvatures, bifurcations and branching points
  • Arterial geometry and hemodynamic factors play a key role in localization, development and  progression of atherosclerosis
  • Stent deployment significantly changes velocity vectors and shear stress
