By Dr Lawrence Dembo, Cardiologist, Murdoch


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.

  • Coronary CT (CTCA) is for diagnosis of equivocal symptoms
  • For symptoms, request CTCA not calcium score.
