Ageing heart cells offer clues to susceptibility of older people to severe COVID-19

Genes that play an important role in allowing SARS-CoV-2 to invade heart cells become more active with age, according to research published today in the Journal of Molecular and Cellular Cardiology. The findings could help explain why age is major risk factor for dying from COVID-19, with people over 70 years at greatest risk, and why the disease can cause heart complications in severe cases, including heart failure and inflammation of the heart.
