We’re working with a leading London hospital in a pilot to help save heart failure patients’ lives.

Patients use a smartphone to monitor their health. It collects data and sends it using Bluetooth to our Telehealth service. Nurses check it and if they see anything abnormal they can take immediate action.

Working with Guy’s and St Thomas’ NHS Foundation Trust, 25 patients will be among the first to trial the smartphone.

As part of a health monitoring kit, it takes daily readings of weight, heart rate, blood pressure and blood oxygen levels.

Kenneth Green, 71, is one of the first to use it. He said: “I make sure I take the readings every day. It’s very easy and, if anything changes, for example my weight fluctuates, the Telehealth nurse contacts me to make sure everything is ok.

“I never had any trouble with my heart before so it feels like extra security. I’m one of the lucky ones. Someone’s keeping an eye on me so I stay well.”

Ian Dalton, BT Global Services’ president of global government and health, added: “It’s been great to have the opportunity to work with an acute hospital to explore how patients with heart failure can use Telehealth to improve their experience of care. Over the last three months we’ve seen the benefit the service can bring to patients like Kenneth.”

Life sciences minister George Freeman is backing the project. He said: “This trial is great news for NHS patients, putting the power in their hands to manage their conditions and providing clinicians with the most up-to-date information.”

Heart failure is a life-threatening condition that occurs when the heart doesn’t pump enough blood around the body at the right pressure. The most common cause is coronary heart disease.

People with heart failure are at increased risk of a stroke and other serious conditions. Around 900,000 people in the UK have heart failure and 30-40% of heart failure patients die within the first year of diagnosis.
