• Background

• Aim

  • • Examine mortality (or prognostic implications)

       in relation to coronary artery disease (CAD)

• Method

  • Published in 2011
  • Multicenter CTA of the coronary arteries
  • consecutive cohort of 23,854
  • without known CAD
  • who presented with.
    • chest pain
      • atypical or
      • typical
  • Time to mortality was estimated using multivariable Cox proportional hazards models.

• Result

  • Identified and classified CAD
    • none (0% stenosis),
    • mild (1% to 49% stenosis),
    • moderate (50% to 69% stenosis), or
    • severe (>70% stenosis).
  • 3  year survival without known CAD

  • 

    

    Survival Related to Number of Vessels Involved

  • 

• Conclusion

  • Among individuals without known CAD, nonobstructive and obstructive CAD by CCTA are associated with higher
    rates of mortality, with risk profiles differing for age and sex.
  • Importantly, absence of CAD is associated with a
    very favorable prognosis.

• Relevance

  • When we identify CAD on any patient who is having a CT scan it is important to make note of
    • mild moderate or severe calcification
    • specify vessels
