Dr Lawrence Dembo on Calcium Score and CTA

Calcium score and CTCA – which test when?

By Dr Lawrence Dembo, Cardiologist, Murdoch

Abstract

The coronary calcium score is a powerful risk factor of a future cardiovascular event. Why? Because calcium is direct, visible evidence of coronary artery disease, while the standard risk factors are only risks of atherosclerosis.

Key messages
  • Calcium score is a powerful risk prediction tool
  • Coronary CT (CTCA) is for diagnosis of equivocal symptoms
  • For symptoms, request CTCA not calcium score.
