Study Summary

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus responsible for COVID-19, enters type II pneumocytes using angiotensin-converting enzyme 2 (ACE2). It is unclear whether ACE inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) increase, decrease, or have no significant effect on ACE2 expression or activity. Therefore, ACEI and ARB may be harmful, beneficial, or have no impact on Coronavirus Disease 2019 severity and mortality. The Specific Aims of this observational study are: (1) Among SARS-CoV-2-positive outpatients, compare all-cause hospitalization and mortality rates between: 1.1 Current users of a range of doses of ACEI/ARB- vs. non- ACEI/ARB-based regimens, and 1.2 Current users of a range of doses of ACEI- vs. ARB-based regimens, and (2) Among those hospitalized for COVID-19, compare all-cause mortality between: 2.1 Current users of a range of doses of ACEI/ARB- vs. non- ACEI/ARB-based regimens, and 2.2 Current users of a range of doses of ACEI- vs. ARB-based regimens.

Primary Outcome

For outpatient Veterans with a positive SARS-CoV-2 test (Aims 1.1 and 1.2), the primary outcome is a composite of time to all-cause hospitalization or all-cause mortality.
