The results showed that higher levels of sACE2 were associated with male sex, cardiovascular disease, diabetes, and older age, which are also the main risk factors for complications and mortality of COVID-19 infections. The indication that male sex and clinical or biomarker indicators of biological ageing, cardiovascular disease, and diabetes might be associated with a specific mechanism leading to higher risk of more severe SARS-CoV-2 infection might be useful for risk stratification concerning COVID-19. The close association between biomarkers and the sACE2 level suggests that biological ageing and cardiovascular disease and dysfunction might lead to increased ACE2 expression and a potentially higher risk for SARS-CoV-2 binding and more severe COVID-19 infection. ./cache/cord-318938-7d731q65.txt ./txt/cord-318938-7d731q65.txt
