Hospital admissions for heart attacks lower than expected

Thousands of people are potentially missing out on life-saving treatment because of the coronavirus outbreak, a study indicates.

Research suggests there had been around 5,000 fewer admissions for heart attacks in England by the end of May.

Admission rates are partially recovering, but remain below expected levels.

The data indicates only two thirds of the expected admissions with heart attacks took place at the end of March 2020.

The study, published in The Lancet, used data regularly collected by NHS Digital from NHS Hospital Trusts in England to get up-to-date information about admissions to hospital.

Researchers found a reduction in admissions with heart attacks in England at the start of the Covid-19 pandemic by comparing weekly rates in 2020 with those observed in 2019.

According to the study, admissions with heart attacks caused by a complete blockage of an artery to part of the heart fell by nearly a quarter (23%).

People with this sort of heart attack are at the highest risk of suffering a cardiac arrest and usually need an urgent procedure to open the blocked artery to the heart, along with medications.

Rates of admission for heart attacks caused by a partial blockage of blood supply to the heart fell by 42%, the study found.

Patients with this type of heart attack need urgent assessment and treatment with medications.

Many may also benefit from an urgent procedure to open a narrowed artery to the heart.

Dr Marion Mafham, clinical research fellow at the Nuffield Department of Population Health, University of Oxford - and lead author of the study, said: "Our study shows that far fewer people with heart attacks have attended hospital during this pandemic.

"It is important that anyone with chest pain calls an ambulance immediately, because every minute of delay increases the risk of dying or experiencing serious complications from a heart attack."

The study also found an increase in the proportion of patients receiving procedures to open blocked arteries on the day of admission, and a reduction in the length of stay.

Senior author Professor Colin Baigent, director of the medical research council population health research unit at the University of Oxford, said: "Some people may still be worried about going to hospital because they fear encountering the coronavirus.

"But the truth is that, by delaying or not going to hospital, people with heart attacks are at much greater risk of dying from their heart attack than catching the virus, and the NHS is ready and able to provide excellent cardiological care."

Researchers say there has been a similar reduction in the numbers of patients attending hospital with heart attacks, and in the numbers receiving surgery to open a blocked artery, in several other European countries, and America, during the pandemic.

Researchers at the University of Oxford, worked with NHS Digital, in collaboration with experts from the University of Keele, the University of Leeds, Imperial College London, University College London, Barts Health NHS Trust and the Royal Brompton and Harefield NHS Foundation Trust.

Dr Sonya Babu-Narayan, associate medical director at the British Heart Foundation, said: "We're extremely concerned about the estimated 5,000 heart attacks 'missing' from the UK's hospitals throughout this pandemic.

"These troubling statistics point to people delaying seeking care for their heart attack, risking death or long-term heart damage.

"A&E attendances for possible heart attacks appear to have bounced back to normal levels, partly thanks to campaigns urging people to seek help if they experience symptoms.

"However, it's no time to get complacent. As the threat of coronavirus appears to ebb and flow, so do people's feelings of fear and uncertainty.

"Thanks to decades of research, prompt treatment for your heart attack could save your life, so if you think you are experiencing symptoms call 999 immediately."
