To Empower CVD Patients to Thrive with Family.

Cardiovascular disease (CVD) is an umbrella term for all diseases of the heart and circulation. As the leading cause of death worldwide, CVD accounts for 17.9 million lives each year, which is 31% of all global deaths. Poor cardiovascular health can cause heart attacks, strokes, heart failure, chronic kidney disease, peripheral arterial disease, and the onset of vascular dementia.

Given that the majority of CVD cases are preventable, there is a huge opportunity to make a difference in improving CVD outcomes. We aim to deliver a user-oriented healthcare service to enable people with CVD to understand, navigate and execute their long-term healthcare programme on a daily basis with family support.


High blood pressure (hypertension) is one of the most important risk factors for CVD.

High blood pressure does not usually have any symptoms. 

The only way to find out if you have it is to get your blood pressure checked. That is why we choose to collaborate with OPPO whose wearable watches provide 24/7 blood pressure detection to avoid the dangers that high blood pressure can cause.

It provides easier blood pressure viewing for users, you can sync OPPO Watch's exercise and health data to the HeyTap Health app on your phone. You can also use the app to manage your custom watch faces, and those functions perfectly fit our user’s needs.

Big Map

CVD has been identified as the single biggest condition where lives can be saved by the NHS. It affects approximately 7 million people in the United Kingdom, with more than 100,000 hospital admissions each year due to heart attacks.

NHS aims to provide all health and social care professionals and multidisciplinary teams with the appropriate level of knowledge, skills and experience they need to deliver effective CVD prevention and care to people with CVD, and at risk of CVD.

We want to explore future solutions to help people with cardiovascular disease, based on the characteristics of service design combined with cutting edge technology.

Research Overview

Overall, we completed a total of four phases of user research to explore solutions:

1. Survey: We first conducted the questionnaire with 30 users to try to understand their lifestyle.

2. Professional Workshop: Considering the medical-related background of our project, we have also taken into account the opinions and suggestions of the medical staff - 2 doctors and 8 pharmacy staff from 9 medical institutions.

3. User Interview: Then, we started to think about how we could help users to solve their dilemmas. So, we interviewed and continued to visit 8 users to better understand their needs.

4. User Behaviour Observation: We conducted a one-month test for 6 main users to see if digital reminders would be helpful. Using either sending a message or Apple notification every day to record their daily routines (essential med, blood pressure measure, diet).


We would like to use a short story to show a scenario/journey of a patient's life. Let's hear about Mark's story. 😲


Define Problems...

  1. Complex Instructions: It’s quite often patients forget to take pills as it doesn't affect life indicators instantly.
  2. Hypertension: People living with CVD need to be aware of their blood pressure 24/7 as such control reduces the risk of emergency cases arising from CVD.
  3. Slack: Changing your lifestyle habits over time is not an easy task.

How Might We...

  • How might we provide a user-oriented healthcare service to enable people with CVD to understand, navigate and execute their long-term healthcare programme on a daily basis?


Our service's unique strength is convenient, customised advice on a daily basis, family intervention, valuable data collection at affordable price.

We found big opportunities in huge potential market sizes, using the user-oriented service to ease the pressure on the public sector. However, long-term management requires users to participate consciously and actively; it is also an ongoing challenge for us.

Impact & Future Prospects

  1. For CVD Patients: Increase healthcare awareness; Build a healthy lifestyle; Develop a more intimate connection with families; Lower the risk of premature mortality.
  2. For Families: Increase family contacts and ties; Families are likely to have similar daily habits. While urging their families, they should strengthen their health management knowledge and promote their own health management.
  3. For NHS and government: Improve the outcome of helping CVD; Help reduce the premature mortality in the UK; Valuable data set on blood pressure from CVD patients.
  4. For sensor Companies: Increase the sales of OPPO watches as portable blood pressure sensors; Improve OPPO's intelligent services, especially digital medical services, which they want to improve in the next generation and enhances brand value.
