People hospitalised with Respiratory syncytial virus (RSV) are more likely to have a serious heart problem related to the virus than those hospitalised with COVID-19, according to international researchers. The team collected data on serious cardiovascular problems among 32,000 people hospitalised with RSV, COVID-19 or influenza, and found one in 10 patients hospitalised for RSV had a serious problem occur. They say the odds of a heart problem were higher for RSV patients compared to COVID-19 patients, both if they had received booster vaccines and if they had not. There was no clear difference in risk between RSV and influenza patients, the researchers say, except they found a lower risk among influenza patients who had received a flu shot.
