Coronavirus can damage the heart, according to a study which found abnormalities in over half of patients tested

The coronavirus can damage the heart, according to a major new study which found abnormalities in the heart function of more than half of patients who had scans.

  • The new findings are significant because they add to a growing field of evidence that suggest coronavirus damages not only the heart but also other major organs.
  • The research, drawing on data from 69 countries, found that 55% of 1,261 patients scanned had abnormally functioning hearts.
  • Around one in seven patients who were scanned showed 'severe abnormalities' which were likely to have a significant impact on their chances of survival and recovery.

More than half of coronavirus patients who received a heart scan in hospitalsdemonstrated "abnormalities" in their heart function, according to a major new study which adds to growing evidence that COVID-19 can damage organs throughout the body.

The new research based on datafrom 69 countries, published in the European Heart Journal and commissioned by the British Heart Foundation, found that 55% of 1,261 patients scanned had abnormally functioning hearts.

Around one in seven patients who were scanned showed "severe abnormalities" which were likely to have a significant impact on their chances of survival and recovery.

A majority 901 patients of those with abnormally functioning hearts had not demonstrated heart problems before, leading the authors of the report to conclude that coronavirus is responsible for causing heart problems.

The study, carried out by researchers at the British Heart Foundation Centre of Research Excellence at the University of Edinburgh, emphasised that the study was limited only to people who doctors had cause to believe had heart abnormalities in the first place.

The new findings are significant because they add to a growing field of evidence that suggest coronavirus damages not only the heart but also other major organs, and raises the possibility that the damage could be permanent in patients.

The Guardian cited early coronavirus studies in China and Italy which found that up to 1-in-5 COVID-19 patients in hospital were suffering from cardiac damage as well as lung damage.

The heart has to work harder in coronavirus patients because the virus causes inflammation and fluid build-up in the lungs, the Guardian reported . That can cause the heart either to fail or for its tissue to become damage, while in some cases the virus can infect the muscle tissue directly.

Professor Marc Dweck, a consultant cardiologist at the University of Edinburgh who helped lead the research said , "COVID-19 is a complex, multisystem disease which can have profound effects on many parts of the body, including the heart. Many doctors have been hesitant to order echocardiograms for patients with COVID-19 because it's an added procedure which involves close contact with patients. Our work shows that these scans are important they improved the treatment for a third of patients who received them."

"Damage to the heart is known to occur in severe flu, but we were surprised to see so many patients with damage to their heart with COVID-19 and so many patients with severe dysfunction. We now need to understand the exact mechanism of this damage, whether it is reversible and what the long-term consequences of COVID-19 infection are on the heart."
