(Press-News.org) Defibrillators are being used in just one in ten cardiac arrests where the lifesaving devices are available, according to new research presented at the British Cardiovascular Society Conference in Manchester.
The research drew upon data from the East of England Ambulance Service and The Circuit, the national defibrillator network developed by the British Heart Foundation (BHF). The Circuit maps the location of defibrillators across the whole of the UK, so that emergency services can direct bystanders to the nearest defibrillator in the event of a cardiac arrest.
They then analysed the density of defibrillators across geographical areas, the number of cardiac arrests, as well as the frequency that defibrillators were used from April to September 2022.
The results found that 1649 cardiac arrests occurred in the East of England in the six-month period. Public access defibrillators were available (within 500m of the cardiac arrest) in 1302 (79 per cent) cases, but only used in 132 (10 per cent) of cases.
The researchers say these findings underline the need for better education and awareness around defibrillators, so that they are used more frequently.
The study, from researchers at the Essex Cardiothoracic Centre (CTC), part of Mid and South Essex NHS Foundation Trust (MSEFT), and Anglia Ruskin University (ARU) also found that there are fewer defibrillators in more deprived areas, compared to the most affluent.
The researchers overlayed data on defibrillator density and cardiac arrests with data from the 2019 index of multiple deprivation. This revealed that Luton, the most deprived area in the East of England had the lowest rates of defibrillators in the region, with 16 defibrillators per 100,000 people, compared to the mean for the East of England of 72 per 100,000 people.
There are more than 30,000 deaths from out of hospital cardiac arrests in the UK each year, and fewer than one in ten people currently survive. Prompt CPR and defibrillation can more than double someone’s chances of survival.
Dr Thomas Keeble, Consultant Cardiologist at Essex CTC which is part of MSEFT, and Associate Professor at Anglia Ruskin University said:
“Our study highlights strikingly low numbers of publicly available defibrillators being used in the event of a cardiac arrest in the east of England area, which suggests that much more needs to be done to promote awareness and education around CPR and defibrillation. It is also concerning to see far fewer defibrillators in the most deprived areas – such a finding should prompt further discussion about more consistent and effective placement of defibrillators in communities.”
Judy O’Sullivan, Director of Innovation in Health Programmes at the British Heart Foundation said:
“Prompt CPR and defibrillation from bystanders can be the difference between life and death, so it is concerning to see low rates of defib use. There are many known reasons for the low use of defibrillators, including not having enough bystanders available at the scene of an emergency, difficulty in accessing a defibrillator at the time when it is needed, or fear of it using it. More needs to be done to encourage people to use these life saving devices when they are available.
“We also know there are thousands of unregistered defibrillators which means their location is not known to the ambulance services. We are calling upon everybody who owns or looks after defib to register it on The Circuit today – this could help save someone’s life.”
Dr Simon Walsh, Medical Director at the East of England Ambulance Service Trust said:
“The East of England Ambulance Service Trust has been working with The Circuit to maximise the number of maintained Public Access Defibrillators on our Computer Aided Despatch system, and since September 2022 we have added a further 1,534 PADs to the database.
“We have also expanded our community first responder and staff responder schemes with the aim of increasing the likelihood that someone will be able to locate the nearest PAD to a patient in cardiac arrest. We continue to work closely with the Essex Cardiothoracic Centre and other partner organisations in the East of England to improve outcomes of cardiac arrests in our communities.”
The study was funded by the East of England Cardiac Network.

Patients with heart disease could benefit from less extensive interventions thanks to cutting-edge technology that creates 3D computer models of blood flow through the heart's arteries, according to research presented at the British Cardiovascular Society in Manchester.
When the research team trialled the VIRTUHeartTM technology with doctors treating heart attack patients, they found that using it would have changed the treatment of more than 20 per cent of patients. In many cases, it would have led to fewer patients undergoing an invasive procedure such ...

Have you ever wanted to convey a feeling but just couldn’t find the right words? Millions of people struggle with a personality trait known as alexithymia, which means “no words for feelings.” Individuals with alexithymia have difficulty identifying and describing their emotions. This trait can harm their social and intimate relationships. They are likely to miss social cues and thus fail to recognize or understand the feelings of others. Past research has suggested that a history of child maltreatment could play a role in developing adult alexithymia.
A new meta-analysis published this month in Psychological Bulletin, led by Stanford ...
Patients infected with beta and delta COVID-19 variants, and those who required hospital stays for COVID-19 infection, were more likely to experience heart issues associated with long COVID, according to a recent Houston Methodist study published in the European Heart Journal – Cardiovascular Imaging. Patients recovering from the omicron variant were least likely to have microvascular involvement.
“This new data expands our understanding of myocardial flow reserve as an important prognostic marker in general and specifically in COVID-19,” said Mouaz Al-Mallah, M.D., corresponding author of the study and director of cardiovascular ...

A randomized trial of older veterans found that hospitalized persons enrolled in a supervised walking program known as STRIDE (AssiSTed EaRly MobIlity for HospitalizeD VEterans) were less likely to be discharged to a skilled nursing facility. However, the authors noted that participation in the program was low and there was no change associated with length of hospital stay or inpatient falls. The study is ...
Tirzepatide is a recently approved treatment for type-2 diabetes. Treatment with tirzepatide decreases body weight while improving glucose metabolism in patients with obesity and type-2 diabetes. Although the drug is designed to activate receptors for glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP), the contribution of activating the GIP receptor in the overall efficacy of tirzepatide is not fully understood. A team of researchers demonstrated for the first time that tirzepatide stimulates insulin secretion in the human pancreas via the GIP receptor. These results contrast with findings in ...
Tinnitus, the ringing, buzzing or hissing sound of silence, varies from slightly annoying in some to utterly debilitating in others. Up to 15% of adults in the United States have tinnitus, where nearly 40% of sufferers have the condition chronically and actively seek relief.
A recent study from researchers at the University of Michigan’s Kresge Hearing Research Institute suggests relief may be possible.
Susan Shore, Ph.D., Professor Emerita in Michigan Medicine’s Department of Otolaryngology and U-M’s Departments of Physiology and Biomedical Engineering, led research on how the brain processes bi-sensory ...
