Since December 2019, a novel coronavirus called SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) has caused an international outbreak of respiratory illness described as COVID-19.
Individuals with a history of cardiovascular disease develop a more severe illness and have higher rates of death.
Because of the potential interaction between RAS blockers and SARS-CoV-2 mechanism of infection, there are ongoing scientific discussions on whether they should be stopped or continued in patients with COVID-19.
It is crucial to determine whether RAS blockers should be discontinued or not in patients with COVID-19.

- hospitalized, not requiring supplemental oxygen
- hospitalized, requiring supplemental oxygen
- hospitalized, requiring nasal high-flow oxygen therapy, noninvasive mechanical ventilation, or both
- hospitalized, requiring ECMO, invasive mechanical ventilation, or both
- death.
