What is cardiac rehabilitation and secondary prevention?
Cardiac rehabilitation (CR) – processes to accelerate recovery and optimise physical, psychological and socialfunctioning to enable people with CVD to live fulfilling lives with confidence.

How can technology support cardiac rehabilitation?
“Digital health” - overarching term, includes eHealth and mHealth
electronic health records
telehealth
computing science – machine learning, artificial intelligence and
‘big data’
wearable sensors

“The two areas that are changing... are information technology and medical technology. Those are the things that the world will be very
different 20 years from now than it is today.”
Bill Gates (2012)
“Machines will not replace physicians,
… but physicians using AI will soon replace those not using it.”
(Di leva, The Lancet, 2019)

What’s required to make digital technology ‘fit for purpose’ in cardiac rehabilitation?
Robust evaluation of new digital health innovations
Disseminating effective health innovations rapidly
Upskilling health providers in these innovations
Empowering consumers to be active participants in digital health
Ensuring equity and access for all - particularly among the
disadvantaged

Know your patients
Engage with patients
Managepatients’ care
Sweet spot
What are the capabilities of digital health?
1. Know your patients
Risk intelligence solutions that deliver population analytics and individual patient profiles to enable proactive care.
2. Engage with patients
Provide health engagement that supports self-management, enhances patients’ experience and improves outcomes.
3. Manage patients’ care
Care management that encompasses evidence-based best practice and appropriate service utilization.

Project 1: Innovative elemonitoring-enhanced Care for CHF (ITEC-CHF)
Background
Chronic heart failure (CHF) is a progressive condition complicated by
episodes of exacerbation, recurrent hospitalisations
Rapid weight gain reflects fluid retention
Daily weight monitoring is an important component of self-
management
< 40% patients monitor weight according to recommendations¹ 1. Jaarsma T, et al. Comparison of self-care behaviors of heart failure patients in 15 countries worldwide. Patient education and counseling. 2013; 92(1):114. OI:10.1016/j.pec.2013.02.017.

Purpose of the project
To develop and trial an automated model of body weight telemonitoring to support clinical surveillance in patients with CHF.

– Fiona Stanley Hospital/Royal Perth Hospital (WA)
- Peninsula Health (Vic)

China (SMART-CR/SP) study
Background There is an urgent need to improve access to cardiac rehabilitation and
secondary prevention (CR/SP) services in China
Innovative CR/SP models that are easy to access, affordable andscalable are required to optimise the management of CHD in China
Mobile health-based CR/SP may be a promising solution

Some take home thoughts….Digital health is promising for many health issues but:
Importance of maintaining patient autonomy
Public trust
Need for transparency behind algorithms - augmented rather than
artificial intelligence otherwise AI is seen as a ‘black box
Requirement to integrate digital health into work flow
Cost effectiveness
How to handle live identified data sets and sharing patient
information across health sectors ?
Legislative issues – the technology needs to drive the legislation!
