Professor Redfern is a clinician-researcher and leader in preventive cardiology, cardiac rehabilitation, digital health and physiotherapy. Her research identified evidence-practice gaps in secondary prevention of heart disease and found patients not participating in traditional cardiac rehabilitation were at the greatest risk. In pursuit of better care for more patients, she conceived and led many cohort studies and clinical trials (quantitative and qualitative evaluations) in digital health and text messaging that have influenced guidelines, systems of care and stakeholders are now focused on a more lifelong, individualised approach with emphasis on survivors who do not attend traditional programs.
