Coronavirus may have a serious impact on the heart, with more than half of COVID-19 patients revealing abnormal scans, a study suggests.
Researchers at Edinburgh University examined ultrasound scans, known as echocardiograms, of 1,261 patients in hospitals from 69 countries.
They discovered abnormal changes to the way the heart was pumping in 55% of the patients, with around one in seven showing evidence of severe dysfunction.
Around 3% of patients had suffered a recent heart attack.
The majority – 901 patients – had no known heart problems before, leading scientists to conclude that COVID-19 itself, the disease caused by coronavirus, may seriously affect the heart.
Among this group, heart scans were abnormal in 46% of patients and 13% had severe disease.
The scans showed abnormalities were almost evenly split between the left and right chambers of the heart.
