鈥楲ike a fitbit in your heart鈥� 鈥� remote pacemaker study to help cardiac patients avoid hospital admissions
Pacemakers will monitor heart patients鈥� activity levels, triggering early healthcare intervention
A study at The University of 野狼社区 will analyse heart patients’ activity levels through their pacemakers, to determine which people are at the highest risk of frailty and help them avoid long hospital stays.
The British Heart Foundation-funded study, supported by Medtronic, aims to help older people living with heart disease and heart failure. By identifying predictors of illness, it is hoped that doctors will be able to treat patients in the community before they become acutely ill. Older cardiac patients with frailty have high rates of long-term and often unsuccessful hospital admissions, and helping them to recover at home could relieve pressure on the NHS.
Cardiac monitoring devices, such as pacemakers and implantable cardioverter defibrillators (ICDs), can record and store data on patients’ physical activity which can be transmitted via a Bluetooth connection. Many patients are able to upload this data from home.
The researchers at The University of 野狼社区, led by Dr Adam Greenstein, will download this data, and use it to analyse whether patients with lower levels of physical activity are more likely to be hospitalised. This may be because they have a virus or infection, or have suffered a fall. If that is the case, in the future it may be possible to intervene before a patient’s health deteriorates to the point of needing to be hospitalised, for example by sending out a community nurse.
The clinical fellowship was awarded £123,000 by the BHF and will last two years, involving 150 patients aged 60 and older, recruited from 野狼社区 Royal Infirmary.
The University of 野狼社区 recently received a £1million Research Accelerator Grant from the BHF to support world-leading research into heart and circulatory diseases, which kill more than one in four people in the UK.
This data can show us how a person’s activity levels correlate with their likelihood of being hospitalised for frailty, and that means we can treat them in their home before they get so ill that they need to be in hospital.
Jim Standing, 75, from Clayton le Dale in the Ribble Valley is one of those taking part in the study. In May 2016, Jim was travelling back from 野狼社区 with his wife from a show when he suffered a cardiac arrest. Fortunately, there was a nurse on the train who gave Jim CPR until paramedics arrived with a defibrillator.
Jim said: “I got on the train, sat down, and simply died. It was terrifying for my wife. I had always been fit and healthy, but my dad died from cardiac ischaemia at the age of 63 and that was always a shadow hanging over me.
“Following a poor prognosis I spent three weeks in 野狼社区 Royal Infirmary and that’s when I started to realise just how lucky I had been. During this time I often wondered what my future might hold, would I be around for my wife's mother's 100th birthday, see my grandson graduate or be able to celebrate our golden wedding anniversary?
“I had an ICD fitted and nine months later I had a quadruple bypass. There has been a steady improvement since my bypass operation and I now feel fine. I’ve equipped my garage with a couple of exercise machines, walk most days and make sure I’m active as possible.
“I'll be forever grateful for all the help and support I’ve received – from the people on the train who saved me, to the doctors and nurses in the NHS. I feel like I owe it to them and to my family to do my best to stay healthy and active, take part in research, and enjoy life.”
Dr Joanne Taylor, the Clinical Research Fellow who is the study’s principal investigator, said: “In geriatric medicine we spend a lot of time with older people trying to work out how mobile they are and how frail. An older person might get a minor illness such as a virus or infection, but it has a disproportionate impact on their physical functioning. They may become unable to look after themselves, and that’s a common reason for people to end up in hospital. We see this particularly with heart failure patients.
“We noticed that cardiac devices are measuring daily physical activity in older people – like a Fitbit in your heart, that’s always on. This data can show us how a person’s activity levels correlate with their likelihood of being hospitalised for frailty, and that means we can treat them in their home before they get so ill that they need to be in hospital.”
BHF Senior Research Advisor Noel Faherty said: “The results of this study could help the thousands of people in the UK who have cardiac devices to avoid having to go to back to hospital for relatively minor illnesses. This would remove a significant burden from the NHS, as well as improving people’s quality of life.
“The British Heart Foundation is the UK’s largest independent funder of research into heart and circulatory diseases, such as heart attack and stroke, and the risk factors which cause them, such as diabetes. Our vision is a world free from the heartbreak caused by these conditions, and we rely on the support of the public to help us get there.”
Margaret Long, 77, from Prestbury in Cheshire had a pacemaker fitted in May 2018. In 2008 Mags began suffering from atrial fibrillation, an abnormal heartbeat. She visited her GP who performed an ECG and a diagnosis came back within half an hour. Mags had two cardioversion procedures – where an electric shock is sent to the heart to restore a normal rhythm – followed by an ablation, where the piece of heart tissue which is causing the abnormal rhythm is destroyed. In 2012 Mags had a stroke, which is more common in people with atrial fibrillation.
In 2016 Mags had a pacemaker fitted to make sure her heart is beating at the right pace. She said: “All those years I had atrial fibrillation, I had to go to Macclesfield A&E so many times. Since having the pacemaker fitted I’ve been able to stay out of hospital. I can be more active – I’ve played a full season of bowls, I can walk a mile in 20 minutes. My cardiologist can see how well I look. I’m so grateful for what’s been done. Life is wonderful. I’m catching up on so many physical things that were nigh on impossible before.
“I usually upload data from my pacemaker every three months and am seen once a year. For me, taking part in this study is a way to help other people in my situation.”
