The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus responsible for coronavirus disease 2019 (COVID-19), is associated with a high incidence of acute respiratory distress syndrome (ARDS) and death. Hypertension and cardiovascular disease are risk factors for death in COVID-19. Angiotensin converting enzyme 2 (ACE2), an important component of the renin-angiotensin system, serves as the binding site of SARS-CoV-2 and facilitates host cell entry in the lungs. In experimental models, angiotensin converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) have been shown to increase ACE2 expression in several organs, potentially promoting viral cell invasion, although these findings are not consistent across studies. Alternatively, ACEIs and ARBs may actually improve mechanisms of host defense or hyperinflammation, ultimately reducing organ injury. Finally, ACEIs and ARBs may have direct renal, pulmonary and cardiac protective benefits in the setting of COVID-19. Therefore, it is unclear if ACEIs and ARBs may be beneficial or harmful in patients with COVID-19. Given the high prevalence of hypertension, cardiovascular and renal disease in the world, the high prevalence of ACEIs or ARBs in these conditions, and the clinical equipoise regarding the continuation vs. discontinuation of ACEIs/ARBs in the setting of COVID, a randomized trial is urgently needed. The aim of this trial is to assess the clinical impact of continuation vs. discontinuation of ACE inhibitors and angiotensin receptor blockers on outcomes in patients hospitalized with COVID-19.

The randomized intervention will be the discontinuation of ACEI/ARBs. In all participants randomized to discontinuation, treating clinicians will be reminded about the medication discontinuation upon discharge and will be prompted to consider re-initiation of the medication at that time if appropriate, per the clinician's discretion.
The randomized intervention will be the continuation of ACEI/ARBs at the doses previously prescribed for patients during their routine care. Clinicians will be encouraged to continue the randomized treatment but will be allowed to change the dose of ACEI/ARB or discontinue these medications if any compelling clinical reasons are identified (such as hypotension, hyperkalemia, acute kidney injury).

Hierarchical Composite Endpoint
The primary endpoint of the trial will be a global rank based on patient outcomes according to four factors: (1) time to death, (2) the number of days supported by invasive mechanical ventilation or extracorporeal membrane oxygenation (ECMO), (3) the number of days supported by renal replacement therapy or pressor/inotropic therapy, and (4) a modified sequential Organ Failure Assessment (SOFA) score. The modified SOFA score will include the cardiac, respiratory, renal and coagulation domains of the SOFA score. How to interpret the rank?: patients are ranked from worst to best outcomes, such that patients with bad outcomes are ranked at the top and patients who have the best outcomes are ranked at the bottom.
Time frame: Up to 28 days
All-Cause Death
Time frame: Up to 28 days
Length of Hospital Stay
This outcome measurement looked at the median length of hospitalization.
Time frame: Up to 28 days
Length of ICU Stay, Invasive Mechanical Ventilation or Extracorporeal Membrane Oxygenation
Time frame: Up to 28 days
AUC SOFA
The Area Under the Curve of the modified SOFA (AUC SOFA) from daily measurements, weighted to account for the shorter observation period among patients who die in-hospital. How to interpret the AUC SOFA?: a higher area indicates more severe disease and/or longer hospitalization.The range is 0.1 to 377.3.
Time frame: Up to 28 days
