Dr Mark Nidorf

  • Cardiovascular Imaging Specialist
  • Spoken languages English


Cardiovascular Imaging Specialist with special clinical interest in non invasive cardiac imaging, echocardiography and the management of coronary disease.

Dr Stefan Mark Nidorf trained in Medicine in Perth Western Australia. He did advanced training in echocardiography at the Massachusetts General Hospital, Boston, Harvard Medical School. He is currently working as a Clinical Cardiologist at GenesisCare in Perth and is affiliated with the Heart and Vascular Research Institute at the Perkins Research Institute. His clinical research interest in atherosclerosis led him to initiate the LoDoCo trials of low dose colchicine for the secondary prevention of coronary disease, the rationale of which has been strengthened by an improved understanding of how cholesterol transitions from an essential molecule into a crystalline form that can act to initiate and perpetuate the chronic and acute manifestations of atherosclerosis.
