Researchers have found that ultrasounds give a better indication of which COVID-19 patients have a higher risk of dying.
Doctors at hospitals across the Mount Sinai system in New York looked at echocardiograms, or ultrasound scans of the heart, for 305 COVID-19 patients and 190 of those had structural heart damage.
The scans gave doctors an indication of which patients had the highest risk for death.
Researchers found it gave a fuller picture than the routinely run blood tests to look for heart damage.
They say ultrasounds could help doctors start treatment early and help patients recover better.
