Clinical Value and Cost-effectiveness of a Personalized Prevention Program (PPP) in Patients With High Risk Stable CHD

To be considered for this study, you generally need to be between 30 and 80 years old. You must have stable coronary heart disease, which means either you've had a narrowing in your heart arteries found in a scan in the last year, or you had a heart attack (Type I or II) in the past year.

There are certain situations that would prevent you from joining. For example, if you've recently been in hospital for a heart attack, stroke, or heart failure within the last month, you'd need to wait until a month after that event. Also, if you have severe heart failure (NYHA class III-IV), uncontrolled irregular heartbeats, severe kidney disease requiring dialysis, or other serious illnesses that might shorten your life, you wouldn't be able to participate.

Additionally, if you have conditions that make it very difficult to exercise, like severe arthritis or certain nerve or bone conditions, you might not be suitable. Lastly, you need to be willing and able to attend all study appointments, follow the study procedures, and use a smartphone app.

If you join this study, it would involve a number of appointments over a period of time. You would first be part of a larger screening phase. If you're identified as high-risk, you might then be asked to join the second part of the study, where you'd be randomly assigned to either receive the Personalised Prevention Program or usual care. The Personalised Prevention Program might involve guidance on diet and exercise, potentially using a special tool to help design your exercise plan, and a smartphone app to help track your progress. Researchers will collect information through questionnaires, blood tests, and potentially other health assessments to see how you're doing. The full duration of your involvement isn't specified but typically these studies involve follow-ups over several years.
