Feasibility of the "Heart-track" Rehabilitative Device Prototype
Condition: Cardiac Infarct; Cardiac Event
MeSH terms: Cardiovascular Diseases; Myocardial Infarction
Study type: Interventional

Summary: 
      Abstract Title: "Heart-track" cardiac rehabilitation device prototype designed for exercise
      training post coronary revascularisation: A usability study Background: Percutaneous Coronary
      Intervention (PCI) is a common surgical procedure for heart attack patients. International
      guidelines recommend that all patients complete phase two (outpatient) cardiac rehabilitation
      (CR) after PCI, as it plays a critical role in reducing five-year cardiovascular mortality
      and the risk of cardiovascular-related hospital admission. Patients in our institution have
      suboptimal exercise compliance and effectiveness during cardiac rehabilitation. Root cause
      analysis identified 'lack of commitment', 'lack of care monitoring and continuity' and 'lack
      of motivation and engagement' to be key contributing factors. Yet, healthcare resource
      limitations necessitate innovation for care continuity and patient engagement. "Heart-track",
      a novel, app-based innovation was created. By 'game-ifying' cardiac rehabilitative exercise
      training program, "Heart-track" guides and tracks cardiac rehabilitation at home at patient's
      comfort.

      Purpose: To explore experiences of app usability in terms of content, functionality and
      design of the prototype "Heart-track" app to improve user experience.

      Methods: Twelve community-dwelling adults who are also active member of cardiac rehab support
      group, aged above 50, and undergone coronary revascularisation for acute myocardial
      infarction at least 1 year before were recruited. Participants were introduced to
      "Heart-Track" mobile app system and its navigational characteristics with standardised
      instructions. Each participant then performed a self-directed Cardiac rehabilitation session
      using the app. Participants rated their experience with the hardware and software components
      of "Heart Track", and their acceptance of it as a cardiac rehabilitation tool. Descriptive
      analysis of quantitative responses were analysed using IBM SPSS software version 19.0
      (Armonk, NY: IBM Corp).

Intervention name(s): Heart Track
Intervention type(s): Device
Intervention description(s): Description of the device: Wearable heart rate sensors are used in Heart-track, and a receiver on a smartphone app. Real-time wireless heart rate data is sent to paired mobile device with a wireless distance of up to 10m. The sensor is able to monitor a heart rate range of 30 to 240 beats per minute.
Another component of Heart-track is a "Heart-track" mobile app which captures and reflect real-time heart rate from the heart rate sensor. The mobile app also includes warm-up and cool down exercises that are gamified and supported on a smart-phone running on Android or iOS platforms.
The HR sensor will be purchased by our collaborator, Immersive Play Pte Ltd.
