Impact of a Digital Solution (CardiCare™) on Cardiorespiratory Fitness Improvement in Patients Discharged From a Phase 2 Cardiac Rehabilitation Following an Acute Coronary Syndrome

Coronary heart disease is a partial inability of the coronary arteries to supply the heart muscle due to their narrowing. There is angina and myocardial infarction. Coronary heart disease is the first cause of non-communicated deaths and years of life lost.

After hospital discharge, a few days following the acute care of a coronary heart disease, a formal Cardiac Rehabilitation programme (CR) is usually provided. CR is a comprehensive programme involving exercise training, risk factor modification, education and psychological support. It is generally sequenced in 4 phases. Phase 1 begins at the hospital and consists of early mobilisation and education. Most phase 2 CR models are based upon supervised ambulatory outpatient programmes. Maintenance (phase 3 and 4) follows the ambulatory programme in which physical fitness and risk factor control are supported in a minimally supervised setting.

Despite high-grade recommendations and abundant clinical evidence, a CR program is not always implemented and the patients are not systematically referred after discharge from a phase 1 CR. Furthermore, compliance to pharmacological treatments and changes in lifestyle and diet are hugely neglected following a phase 2 CR and an important number of patients resume a sedentary lifestyle.

A growing body of evidence supports the use of digital tools such as smartphones and tablets in helping the patients achieve their goals in terms of physical exercise, risk-factor reduction and diet improvement.

Ad Scientiam has developed CardiCare™, a mobile application intended to provide a personalised physical training plan contributing to stabilise or improve cardiorespiratory fitness through improvement of VO2max.

The mobile application CardiCare™ is to be used by patients after an acute coronary syndrome, graduated from a phase 2 cardiac rehabilitation program in a cardiac rehabilitation centre and entering in phase 3 CR.

The mobile application CardiCare™ consists of several modules:

• A physical activity recommendation engine, providing personalised weekly activity schedule, self-adapting to the patient's clinical characteristics, physical capacity and sport preferences through a proprietary algorithm
• Self-administered questionnaires to assess perceived exertion, chest pain, weight variations, patient's quality of life
• Passive monitoring of the patient's physical activity through Apple's HealthKit and Google's Fit
• Informational content about cardiovascular diseases, risk factor reduction and chest pain action plan The investigator's work hypothesis is that, compared to standard care, CardiCare™ will stabilise or improve the cardiorespiratory fitness (VO2max) acquired post-CR.
