Coronavirus: Heart scans of more than half of COVID-19 patients abnormal, scientists find | Science & Tech News

According to a study, the coronavirus can have serious effects on the heart. More than half of the COVID-19 patients show abnormal scans.

Researchers from the University of Edinburgh examined ultrasound examinations, so-called echocardiograms, of 1,261 patients in hospitals from 69 countries.

They found abnormal changes in heart rate in 55% of patients, with around one in seven showing signs of severe dysfunction.

Around 3% of patients had a recent heart attack.

The majority – 901 patients – had no known heart problems before, which led scientists to the conclusion COVID-19 even caused by the disease Corona viruscan seriously affect the heart.

In this group, heart scans were abnormal in 46% of patients and 13% had a serious illness.

The scans showed that the abnormalities were almost equally divided between the left and right ventricles.

How often heart damage occurs in COVID-19 patients is unclear.

The team emphasized that all patients in the study were hospitalized and suspected of having heart complications.

As a result of their scan, treatment was changed in a third of the patients, including the administration of medicines for heart failure or more careful control of fluids and therapy to support heart function.

Professor Marc Dweck, who led the research, said: "COVID-19 is a complex multi-system disorder that can have profound effects on many parts of the body, including the heart."

He said many doctors have been reluctant to order echocardiograms for patients with COVID-19 because it is an additional procedure that involves close contact with patients.

"Our work shows that these scans are important – they have improved treatment for a third of the patients who have received them," he added.

"Heart damage is known to be associated with severe flu, but we were surprised to find that so many patients with COVID-19 and so many patients with severe dysfunction have suffered heart damage.

"We now have to understand the exact mechanism of this damage, whether it is reversible and the long-term consequences of COVID-19 infection for the heart."

The Cardiovascular Imaging study was funded by the British Heart Foundation (BHF) and published in the European Heart Journal.

Dr. Sonya Babu-Narayan, deputy medical director at the BHF and consultative cardiologist, added: "This global study, conducted at the height of the pandemic, shows that we have to look for heart complications in people with COVID-19 so that we can treat them can adjust if necessary. "
