Home Heart Failure Monitoring - without the hassle


Heartfelt Technologies exists to help patients, their families, carers and doctors, to reduce hospital re-admission rates from congestive heart failure de-compensation.

This is a big problem: heart failure costs the NHS about two billion pounds per year, and statistics show that one in five people will suffer from heart failure (it is the most common cause of hospitalisation for those aged over 65), and half of those affected will have multiple hospital emergency visits as a result. However, it is estimated that three-quarters of these repeat emergency admissions could be avoided.

We are developing a device to monitor heart failure in the home, whilst fitting naturally around the patient's lifestyle. What this means for the patient and their carers is one less thing to worry about with their often complex drug and monitoring routines; for the doctor this means consistently collected data to help patients to live longer, healthier lives.

Heart failure occurs when the heart is unable to pump sufficiently to maintain blood flow to meet the body's needs. It starts when the heart is damaged or weakened, however it doesn't mean that your heart suddenly stops working.

This is a chronic medical condition, commonly compensated using drugs, but de-compensation leads to lengthy and costly emergency hospital admissions. Heart failure is the most common cause of hospitalisation in patients over the age of 65.

The main symptoms of heart failure are:
  • Shortness of breath
  • Excessive tiredness
  • Leg swelling (edema)
  • Rapid or irregular heartbeat (tachycardia)
  • Persistent cough
Common causes of heart failure are:
  • Coronary artery disease (inc. a previous heart attack)
  • High blood pressure
  • Atrial fibrillation
  • Excess alcohol use
  • Infection
  • Other cardiomyopathies (complications) of an unknown cause

Heart failure can also be called congestive heart failure, left-sided heart failure, right-sided heart failure, systolic heart failure, or diastolic heart failure.


Heartfelt Technologies is developing a video-based solution to in-home patient monitoring.

After a heart failure, patients are typically discharged and asked to monitor their health, and receive regular visits from healthcare professionals. At this point our monitor can be installed in the patient's home by the carer, as simply as a picture hung on a wall.

Our device is a camera system, which automatically captures cardiovascular information whenever the patient simply walks past the monitor.

The data is then transmitted to ‘the cloud’ for further processing and flagging of high-risk patients. Once flagged, our data feeds into existing telemedicine monitoring systems allowing carers and medical professionals to take prompt action.
